Metso PTI's consulting services are tailored to suit the requirements of our customers and can either involve the

design or optimisation of the entire process (mine to plant) in a Process Integration and Optimisation (PIO)

project or be a focused study on a particular section of the operation. Projects may include ore characterisation;

ore tracking to link ore properties and blasting practices with plant performance; design and optimisation of

blasting, comminution, flotation and dewatering processes; and reduction of water and energy consumption.

We also offer support during commissioning, throughput forecasting and geometallurgical modelling, pit-to-port

product tracking for supply chain optimisation, and high level training services.

The optimisation and continuous improvement services we conduct deliver significant impacts to our clients. In

over 400 projects conducted globally we have achieved considerable increases in the production of our

customers operations (typically ranging from 5 to 30%) with little or no capital expenditure. This represents

millions of dollars in increased revenue for our customers. In addition to increased production (throughput and

metal recovery), our improvement projects can also deliver cost and energy reduction, as well as overall process

efficiency increases (from the mine to the plant). In order to provide solutions and maintain the benefits of our

optimisation and continuous improvement services, we work extensively and very closely with the mining

operations. It is common for our team members to spend 30 to 50% of their time onsite.

PTI services are value-added and are sold on a consulting basis (charged per day) or a number of other

commercial arrangements (e.g. gain sharing, Improved Performance Alliance agreements, etc.). Our services and

products can also be combined or packaged with other Metso equipment and services.

Iduapriem, AngloGold Ashanti Mine in Ghana

“I am delighted to report that we are seeing immediate benefits with

regards to circuit throughput as result of the project conducted by PTI.

An upgrade of this circuit was conducted in 2009 and the plant was

subsequently rated at 4.38 Mtpa. Indications are that we will now be

capable of achieving 4.7 Mtpa. A quick calculation suggests an increase

in value to the operation of approximately $400 million over the life of

mine”.

Ian Smit, AngloGold Ashanti, Vice President – Metallurgy

Process Integration and Optimisation (PIO)

The mine is essentially a series of operations that are inter-connected and therefore inter-related with the

performance of one operation affecting the performance of another. Traditionally these operations have been

analysed and optimised in isolation.

As part of our Process Integration and Optimisation (PIO) services we analyse each process (mining,

comminution, and separation) in the context of the whole operation. Each process is optimised within the

constraints imposed by the other processes to develop integrated operating and control strategies from the

mine to the plant. We have been very successful in helping our customers to increase their profitability by

delivering continuous improvements in production, efficiency, and asset optimisation, while minimising the

overall cost per tonne and environmental impact.

The CEEC medal is awarded to an outstanding published

paper and case study, profiling beneficial strategies for eco-

efficient comminution. In 2012, Metso PTI in conjunction with

Antamina were awarded the CEEC Gold Medal for the paper

“Optimisation and continuous improvement of the Antamina

Comminution Circuit” presented at the SAG 2011 conference.

The project delivered an energy saving of 25% to Antamina.

Projects are tailored to suit the requirements of the customer, but usually involve the following four steps:

1. Scoping Study This step includes the collection of historical data and information to identify problems, processing

bottlenecks and opportunities for improvement. Detailed analysis of these data and information is then

used to prepare a project proposal.

2. Benchmarking and Optimisation Operational data is collected rigorously through audits and comprehensive surveys of the key processes (drill

and blast, crushing, grinding, flotation, etc). PTI staff use mathematical models, ore characterisation data,

their database of operational data and their extensive experience to identify strategies to optimise the entire

process for different ore types and domains.

3. Validation and Implementation A detailed plan is developed to implement optimisation strategies which have merit based on mine and

plant constraints and a cost/benefit analysis. Key performance indicators are measured during the

implementation to quantify improvements and fine tune recommendations.

4. Sustaining the Benefits Recommended process changes are incorporated into managerial and site operating procedures, and

operators and engineers are trained to ensure the benefits are maintained over the long term.

Ore Characterisation

In-situ ore properties govern the ultimate performance that is achievable in all m operations. PTI can implement

or advise customers on the appropriate testing programs to establish an ore’s blastability, grindability and

floatability.

PTI has laboratory and pilot plant facilities in Sorocaba, Brazil; Brisbane, Australia; and Tampere, Finland. At these

facilities PTI conducts commercial laboratory breakage test work such as the internationally recognised and

industry standard JKMRC and SMC breakage tests, as well as other ore characterisation and process evaluation

tests.

Rock structure measurements include Rock Quality Designation (RQD), Fracture Frequency and joint mapping.

The main rock strength measurements include Point Load Indices (PLi), Unconfined Compressive Strength (UCS),

Drop Weight Indices (DWi), Rod and Bond Ball Mill Work Indices (RBMWi and BBMWi). These are used to

characterise the ore in terms of breakage behaviour in the blast and comminution stages and influence

throughput. Assays, liberation and laboratory flotation test results are used to determine the behaviour of the ore

in flotation processes and determine grade-recovery performance. These parameters are required for modelling

and simulation optimisation studies, and can also be correlated with circuit performance and used in

geometallurgical modelling, throughput forecasting and mine planning.

Ore Tracking from Mine to Mill (SmartTag™)

The SmartTag™ ore tracking system, developed by Metso PTI, allows parcels of ore to be tracked from the mine,

through crushing and finally into the grinding mills. The SmartTags™ are robust passive radio frequency (RFID)

tags. These tags are placed with the ore in the mine (in blast holes, muckpiles, etc), and the starting location (ore

source) of each unique tag is stored in the SmartTag™ database. The tags survive blasting and travel with the ore

through the process; they do not have an internal power source, so they can remain in stockpiles and ROM pads

for extended periods of time. Antennas to detect the SmartTags™ are located at critical points in the process

ahead of the milling circuit. Tags can be detected a number of times and provide valuable information on

material movements. In particular, they make it possible to link the physical ore properties associated with the

ore in the mine to the time-based performance data of the plant.

The SmartTagTM system is an essential tool in Process Integration and Optimisation (PIO). It allows tracking and

correlation of the ore characteristics with important operating parameters in the mine and processing plant, such

as ore dilution, fragmentation, stockpile residence times, segregation, throughput, energy consumption, metal

recovery, etc. This allows optimisation of the system as a whole. Operating parameters and control strategies in

the mine and plant are adjusted and optimised for different ore types; reducing operating costs, maximising

throughput and increasing profitability.

More information on the SmartTag™ system can be found on page 19. The SmartTagTM technology has been

recognised for its innovativeness, winning the 2010 iAward.

Figure 2 – SmartTag™ Ore Tracking – Winner of the 2010 iAward

The SmartTagTM system can also be used to mark and track ore from mines through ports to their final

destinations off-shore, i.e. from Pit-to-Port (see page 20). Additionally, the GeoMetsoTM system uses SmartTagTM to

automate geometallurgical modelling by updating the block model with plant performance data in real time

(see page 15).

Drill and Blast Optimisation

Blasting is the first stage of comminution in most mining operations and should not be seen solely as a means of

reducing rock size sufficiently for load and haul activities. The Run-of-Mine (ROM) size distribution has a large

impact on the performance of downstream crushing and grinding processes.

The in-situ ore properties, drill and blast pattern and properties of the explosive govern the size distribution of

rocks produced from a blast and energy efficiency of the blast. PTI has blast fragmentation models and systems

that can be used to assess the optimum blast conditions required for a particular ore type. The aim is to produce

a ROM size distribution that will maximise throughput and the efficiency of comminution in the subsequent

crushing and grinding operations.

Figure 3 - Optimum Blast Parameters Being Determined Using Measurement and Modelling Techniques

SmartTagTM ore tracking and detailed auditing of the blasting and processing operations are used to develop site

specific predictive models for each operation (blasting, comminution, separation). Using these models, the blast

design is optimised for different ore domains, and a “cookbook” is generated which provides a “recipe” for

operations, i.e. an optimised blast design for each ore domain.

Blasting according to this cookbook provides a

more consistent and optimised feed size

distribution to the downstream processes,

increasing throughput, process stability and

efficiency. Following the cookbook also avoids

excessive blasting in softer ore domains, thus

reducing energy consumption and costs, and

preventing the excessive production of ultrafines

that can be detrimental to some downstream

processes (e.g. in heap leach, iron ore lumps/fines

ratio).

Wall Control Blast Design and Damage Control

The goal of wall control blasting is to make the transition from a well-fragmented rock to an undamaged slope in

as short a distance as possible. Effective wall control blast designs achieve safe and stable slopes while obtaining

the required fragmentation. Wall control blasting is a process of continuous improvement. Near-field vibration

measurements and modelling are carried out during this process. PTI has extensive experience in wall-control

blast designs, near-field vibration measurement and modelling. The expected outcomes and benefits from our

studies are as follows:

» Optimum blast designs for both improved fragmentation and wall stability,

» Measurement of vibration and/or movement at the final/interim walls with current and

recommended blast designs,

» Determination of the best wall-control blasting technique at different sections of the pit.

Comminution Circuit Design and Optimisation

PTI has vast experience in comminution circuit design and optimisation of operating and control strategies

which can increase circuit throughput, reduce energy consumption and costs. PTI expertise includes traditional

equipment and circuits such as staged crushing, SAG/AG mills, pebble crushers, rod and ball mills, closed or open

circuits with screens or hydrocyclones, as well as alternative flowsheets and technologies such as HPGR, VRM,

stirred mills, fine screening and dry classification.

In optimisation projects, PTI uses ore characterisation data, comprehensive plant surveys, and historical

operational data to develop site specific models for the comminution processes. PTI also has an extensive

database of operational data. This is used for benchmarking existing operations and also to develop Greenfield or

expansion projects. Comminution models are used in simulation studies along with extensive industrial and

consulting experience to assess the comminution processes, including circuit configuration, operational

parameters and the key design variables of the system. This allows debottlenecking and optimisation of existing

circuits, evaluation of expansion options, design of new circuits, and evaluation of different flowsheets and

equipment options. Equipment from within and outside of the Metso portfolio can be compared, evaluated and

optimised.

Figure 5 - Survey Data Are Used to Develop Comminution Simulation Models

The operation of a comminution circuit (in particular the throughput and energy consumption) is often strongly

influenced by the ore hardness and the feed size distribution received from blasting. Additionally, changes to the


Con

comminution product size can affect the downstream processes such as flotation and result in recovery losses.

PTI conducts comminution optimisation with a fundamental understanding of these upstream and downstream

interactions to provide solutions that deliver the best outcome for the overall operation.

Flotation Circuit Design and Optimisation

Lost recovery in the flotation circuit results in lost revenue. PTI has expertise in flotation circuit operation,

characterisation, modelling and simulation techniques. Characteristics such as bubble size, bubble load,

superficial gas rate (Jg), froth stability, froth transportation and froth depth can be measured to identify possible

avenues for improving cell performance. This information, along with detailed surveys and historical operating

data are used in modelling and simulation techniques. These techniques, together with extensive industrial and

consulting experience and database are used to evaluate existing or new operations, and highlight opportunities

for improvement in performance.

PTI can identify relationships between grind size and the flotation grade-recovery performance. This enables

integrated optimisation of the blasting, comminution and flotation operations. Economic balance and trade-off

between grind size (throughput) and flotation recovery can be determined using this holistic approach.

Figure 6 – Bubble Sizing, Bubble Load Device and Flotation Simulator

3m3 RCS Flotation Test Cell

It is difficult to measure the effect of operational and design changes in industrial flotation circuits due to the size

and complexity of industrial plants and variability in the feed. Therefore, PTI developed a portable, fully

instrumented 3m3 test cell to enable flotation testing of key parameters (air rate, froth depth, feed flowrate,

impeller speed, impeller size, reagent scheme, froth launder configuration) at a realistic scale. The cell is

controlled by a PLC to enable stable operation and has been designed so that representative samples of all key

process streams can easily be collected in a safe manner.

The test cell is available for hire to mine sites, and PTI can provide assistance with the development of the

experimental program and specialists to perform the test work. Recent consulting and research projects that

have been undertaken include: evaluation of reagents, investigation of circuit configuration options, exploration

of different launder configurations, energy studies, and examination of the effect of density and turbulence.

Optimisation of Coal Preparation Plants (CPP)

The processes and challenges in coal preparation are quite different to those of metalliferous operations. PTI has

expertise in optimising dense medium circuits, coal flotation, and gravity separation processes such as spirals and

teetered bed separators. Equipment performance data such as RD50 and Ep can be measured for dense

medium baths or cyclones, spirals and teeter beds. For flotation, an often-neglected area of CPP operations,

characteristics such as bubble size, bubble load, superficial gas rate (Jg), froth stability, froth transportation and

froth depth can be measured. This information, along with coal washability data, survey and historical data are

used to develop site specific models for each of the processes. The models are integrated for total plant

simulation and optimisation, and opportunities for improved performance are highlighted.

Figure 8 - Coal Preparation Plant Simulator

Optimisation of Water Use

Most current mineral processing technologies rely on wet processing, and consequently consume water. It is

possible to significantly reduce water consumption by evaluating water reticulation circuits, available water

sources and dewatering equipment.


Con

es

PTI can assist with the establishment and estimation of the current site water balance, which is fundamental to

reducing water consumption. Based on this, opportunities to improve water utilisation are identified. Some

typical water saving opportunities with which PTI can assist, include:

» Identifying output streams from which additional water can be recovered

» Identifying possible alternate water sources / alternate uses for discard water streams

» Assessing the suitability of alternate waters to the metallurgical process

» Optimising the performance of existing dewatering equipment (e.g. increasing thickener underflow

density)

PTI would then typically calculate a new, estimated water balance for the operation, quantifying likely water

savings and highlighting changes to the current water circuit / dewatering equipment which will be necessary in

order to realise these savings.

Geometallurgical Modelling and Throughput Forecasting

To maintain long term profitability it is important to have the ability to accurately predict the future performance

of the comminution and flotation circuits as well as their interaction with mining practices. To do so, it is

necessary to have both an accurate description of how these circuits behave as well as a detailed description of

the ore body in relation to relevant rock characteristics. This combination of geology and metallurgy to create a

geologically or geotechnically based predictive model for mineral processing plants is known as geometallurgy.

This provides a link between the performance of the process, or efficiency of the extraction, and the physical

properties of the ore. Geometallurgical modelling enables throughput and metal recovery forecasting, strategic

planning and optimisation for different ore types in order to maximise the profitability of the operation over the

life of mine.

PTI’s approach is to use the mine’s existing data and block models as the framework for developing

geometallurgical models. The process starts with ore characterisation to define ore domains within the deposit

that will behave similarly throughout the blasting and comminution processes. The SmartTag™ ore tracking

system is used to track the characterised ore from the mine to the plant. With the ore source and characteristics

known, detailed audits of the blasting and processing operations are used to develop site-specific predictive

models for each operation (blasting, comminution, separation).


Consulting

Services

Figure 9 – Colours used to Delineate Different Ore Domains on an Image of an Orebody

Together, these models indicate how the whole process will respond to different ore types and operating

conditions in the mine and the plant. Using these predictive models, the blast design is optimised to generate

optimal Run-of-Mine (ROM) fragmentation for all ore types, and downstream processes are adjusted accordingly.

The models also allow prediction of throughput and recovery performance for each ore domain, and when

combined with the mine plan enable production forecast for the Life-of-Mine (LOM). They can also be used to

identify potential bottlenecks, process constraints and opportunities for improvement.

GeoMetsoTM – Automated Geometallurgical Modelling

For geometallurgical modelling to be effective it is necessary to have a high degree of confidence in the data

collected, and to link the plant performance with the ore properties. Metso PTI has developed GeoMetsoTM, which

uses the SmartTag™ ore tracking system to automatically update block models and mine plans with actual plant

performance data in real time. More information on the SmartTag™ system can be found on Page 19.

SmartTagTM technology is used to continuously track parcels of ore from the mine through the process and is

linked with the plant DCS to provide actual plant performance data (throughput, recovery, grade, etc.) for each

ore type and blast conditions. These data are automatically compared with model predictions and updated in

the block model in real time using the SmartTagTM software. This process is illustrated schematically in Figure 10.

Therefore, the block model is continuously populated and refined with actual plant data, eliminating the need for

further expensive ore characterisation tests and improving the accuracy and predictive abilities of

geometallurgical modelling.

Figure 10: SmartTagTM use in GeoMetsoTM

More accurate geometallurgical modelling and throughput forecasting can improve reconciliation and long term

mine planning. Additionally, capital expenditure to meet production requirements can be predicted well in

advance. In the short term, the plant receives advance notice of the ore type/s about to be processed and

adjustments can be made to operating conditions to optimise plant performance.

Support during Commissioning

There is often a considerable delay between the first mechanical commissioning of a plant and the time when it

achieves optimum metallurgical performance. This delay represents a considerable loss in potential revenue. PTI

can provide the process expertise and support required to rapidly achieve process targets during comminution

and flotation circuit commissioning. This support is provided on site followed by remote support where the

consulting engineers can provide advice from afar by accessing the plant’s DCS systems. (4)

PTI Products

PTI have developed a number of products to help maintain optimum operation at customer sites, including:

SmartEarTM

SmartEarTM is robust SAG mill acoustic monitoring system that measures sound levels in different frequencies

making it possible to estimate steel on steel strikes. The system can be used in mills with steel or polymet liners,

and helps to prevent liner damage caused by the impact of grinding balls through the detection of excessive

metal on liner strikes. SmartEarTM also identifies anomalous noises and can indicate the presence of large foreign

objects in the mill (feed chute plates, shovel teeth, etc.) or when liners or lifters have come loose. It can also be

used to improve grinding circuit control; it can detect mill overload, and can also provide an estimate of the

filling level when used in conjunction with SmartSAG. The system also provides a filtered audio signal from the

mill to the control room, which is a popular feature with operators as they can listen to the mill from the control

room without the background noise from the plant.

The SmartEarTM system is composed of microphones with flat response, a signal transducer, transmission system,

and software to process the information. The transduced signal can be transmitted as direct transmission

through cables, by optical fibre, or wirelessly.

Figure 15 – SmartEar™ Installation Schematic

The software processes the signal in terms of audible intensity (dB) and frequencies (Hz), and uses three pre-

configured filters to monitor the charge of the mill, liner impacts, and abnormal events.

SmartTag™

SmartTag™ is an ore tracking system that uses low-frequency RFID tags encased in a ruggedised polymer shell to

track parcels of ore. In Mine-to-Mill applications, SmartTags™ are inserted into the stemming column of blastholes

and/or in muckpiles, stockpiles, etc. The unique identifier (ID) of the SmartTag™ and its blast hole or spatial

coordinates are recorded using a PDA with an integrated SmartTag™ reader. The polymer shell is strong enough

to protect the SmartTag™ from the shock of the blast, and transit through shovels, trucks, crushers and stockpiles.

Figure 16 – SmartTag™ RFID Device , Ruggedised PDA, Antenna installed under conveyor belt

The SmartTags™ travel with the ore and are detected by antennas at strategic locations in the process. Typically,

antennas are installed above or below the conveyor belts after the primary crusher, secondary and/or at the SAG

Mill feed. As the SmartTags™ move past the antennas, the SmartTag™ ID is transmitted via an ethernet or fibre-

optic connection to the central SmartTag™ server.

The SmartTagTM ID, tag origin (spatial coordinates in the mine), time of detection and detection location in the

plant are stored in the database. This provides a link between the origin of the ore (ore characteristics and


Prod

blasting performance) and the time-based performance data of the plant. The SmartTag™ data can be viewed,

manipulated and exported using the SmartTag™ software.

Figure 17 – SmartTag™ Mine to Mill Data Path

SmartTagTM is also being used to automate geometallurgical modelling in the GeoMetsoTM system (see page 15).

Additionally, the SmartTagTM application is being extended to track ore from Pit-to-Port and beyond as described

in the following section.

Pit-to-Port Product tracking using SmartTagTM

Iron ore and coal operations often have complicated product marketing and supply logistics, commonly with

products of different quality specifications and contained value. Currently this is typically managed with complex

software programs that model product stockpiles, and rail and port schedules. These programs record and

reconcile the tonnage, quality and value of bulk materials from mine to point of export or consumption.

However, these systems rely on many assumptions, and cannot be validated easily. Discrepancies arise, and

problems ensue with payment from customers.

The SmartTagTM system can be used to track product through the complete supply chain; from the mine through

the entire transport chain (road, rail, port) and even to the final location were the product is delivered to the

customer. This provides a mechanism to validate software and management tools.

Properties such as grade, shape, texture, moisture, ash, sulphur, phosphorus, energy content, etc can be tagged

and tracked. This facilitates optimisation of plant operation, sorting, blending and homogenisation to maximise


Products

the value of the final product. The system also provides more accurate reconciliation, and allows monitoring and

optimisation of product supply and transport logistics.

Figure 18 - Pit to Port product tracking

SmartSAGTM

SmartSAG is an application of the dynamic model designed by PTI that performs online estimations for the key

parameters of a SAG mill. It is based on a population balance model extended with empirical formulations to

calculate power and slurry flow. This enables estimation of the charge distribution of the mill. The model uses

inputs such as ore fresh feed rate, feed size distribution, and water flow rates to estimate the power

consumption, charge profile, angles of the toe and shoulder, charge radius, pool formation, among other

variables.

The system utilises standard communication protocols for

interfacing with existing process control systems when used

as a real-time soft sensor. However, it can also be configured

to replay historical data when used offline. This provides

more flexibility for trouble-shooting. A simulation mode is

also provided to predict the mill performance over manually

controlled operating ranges.

Metso PTI has strong associations with several universities including: Hacettepe University, University of Sao

Paulo, University of Rio Grande do Sul, University of Queensland, Julius Kruttschnitt Mineral Research Centre,

McGill University and University of British Columbia. PTI’s contribution can include financial support for student

projects, student supervision, provision of guest lecturers, supply of equipment, employment of students to

provide training, and collaboration on research projects.

Customer Driven Research Projects

Research areas are identified through our consulting projects and strong links with customers; this ensures the

research is relevant to the industry. Currently, in the industry there is a strong drive for more sustainable and

efficient technologies; thus, one of our main research projects is the “Development of a Resource and Eco-

Efficient Mining Process”. Additionally, PTI develop specialised measurement systems and instruments to help

improve customer operations. In the past this resulted in the development of the award winning SmartTag™ ore

tracking system that is now widely used around the world. Presently, PTI is investigating a SmartRip detector for

conveyor belt protection and a SmartGap system for measuring crusher gap.

Development of a Resource and Eco-Efficient Mining Process

The mining industry is facing growing challenges associated with the cost of energy, limited water resources,

impending carbon taxes, more stringent legislative requirements and lower grade ore deposits that are

increasingly difficult to treat. Therefore, the search for more sustainable and efficient technologies and practices

is becoming increasingly important.

To address this need, PTI is conducting a research and development project to investigate alternative

technologies and practices in mining and minerals processing that reduce the usage of energy, water and

greenhouse gas emissions, while minimising waste and maximising value. The focus is on improving resource

efficiency; creating more value with less impact, and consequently a better economic return from the available

resource.

There are technologies available today to enable development of a mining and processing flowsheet that is

significantly more eco-efficient compared to current industry practice. However, these technologies need to be

evaluated, validated and, in some cases, adapted or modified. These also need to be considered in the context of

the entire operation to deliver the optimum overall resource efficiency. The proposed integrated mining process

may incorporate the following:

» High intensity selective blasting (HISB) to improve fragmentation and reduce the energy requirement of

downstream comminution.

» In-pit crushing and conveying (IPCC) can eliminate the use of diesel and is a more efficient

transportation method than conventional truck and shovel operation.

» Pre-concentration using screening and/or bulk ore sorting could be implemented to discard barren

material prior to processing, significantly improving resource efficiency by upgrading below cut-off

grade material and/or increasing production rates per tonne treated.

» Alternative energy efficient and dry comminution technologies such as vertical roller mills (VRM) or high

pressure grinding rolls (HPGR) and air classifiers may be incorporated in new plants. While in existing

operations with wet grinding circuits, fine screens may be used to improve efficiency.

» If coarse particle flotation can be enhanced, the energy consumed in previous grinding stages could be

significantly reduced by delivering a coarser product to flotation.

» Finally, filtration and dry stacking of tailings can be implemented to reduce water consumption and

reduce reclamation and closure costs (due to reduced footprint, easier construction, and the possibility

to rehabilitate progressively).

SmartRipTM

SmartRipTM is being developed by PTI with the objective of detecting rips and other damage to conveyor belts,

thus helping to schedule maintenance and prevent downtime. The aim is to produce a non-contact instrument

that is capable of detecting rips in real time, can operate continuously, is relatively inexpensive and easy to install

and commission.

The original concept was to use a line laser and camera; however, this technique provide unsuitable for the harsh

mining environment. A concept was developed using heat signatures as this is now a cheaper and more viable

option. Heat signatures have been shown to be able to detect scrapes, rips and holes in the laboratory with no

environmental issues (dust is invisible). Final proof of concept on an industrial scale is required before

commercialising SmartRipTM as a product.

Laboratory and Pilot Plant Services

PTI offer crushing, grinding and flotation test work on supplied ore samples using state-of-the-art laboratory and

pilot plant equipment. PTI have laboratories and pilot plant facilities in Brisbane (Australia), Sorocaba (Brazil) and

Tampere (Finland). We are expanding into other countries so we have facilities closer to customers to provide

more cost effective and faster services. Results of any test work can be supplied directly to the client for in-house

analysis or alternatively interpreted by PTI engineers, providing a report of recommendations.

The available equipment includes: JKMRC drop weight tester, point load tester, rod/ball mills operating in batch

or continuous state, laboratory and pilot scale flotation equipment, strain-gauged crusher, and pilot scale HPGR.

Also, our Brisbane facility is co-located at the QCAT Queensland Centre for Advanced Technologies, giving us

access to Commonwealth Scientific and Industrial Research Organisation (CSIRO) laboratory and pilot plant

facilities.

PTI can conduct commercial laboratory breakage test work such as the internationally recognised and industry

standard JKMRC and SMC breakage tests. These tests are important inputs for modelling and simulation of

comminution circuits for optimisation and design. Where applicable, point load testing can offer a cheaper

alternative for ore characterisation than Unconfined Compressive Strength (UCS), and PTI have an extensive

database allowing estimation of UCS from point load test results. In addition to laboratory scale flotation testing,

PTI have developed a 3m3 test cell to enable flotation testing of key parameters (air rate, froth depth, feed

flowrate, impeller speed, impeller size, reagent scheme, froth launder configuration) at a realistic scale, see page

12 for more information.
