The otation concept The RCS otation machine is the latest design touse the circular tank concept and combines the

benets of circular cells with the unique features of the mechanism to create the ideal conditions tomaximise otation performance for all roughing,cleaning and scavenging duties.

Metso oers the full range of cell volumes requiredfor modern ore processing plants with cell sizesfrom 5 to 200 m3.

DV™ Flotation mechanism

The patent-protected DV™ (Deep Vane) Mechanism impeller consists

of a unique arrangement of vertical vanes with shaped lower edgesand air dispersion shelf.

The mechanism design produces powerful radial slurry pumping to

the cell wall and gives strong return ows to the underside of the

impeller to minimize sanding. Additionally it is the only mechanism

to give maximum slurry recirculation to the upper part of the

impeller.

Vertical diuser vanes promote these radial ow patterns and com-

pletely eliminate slurry rotation in the tank.

Reduces operating costs:

• Mechanism designed to give maximum bubble

particle contact for improved coarse and ne particle recovery.

• Impellers and diusers are supplied in high abrasion-resistant

elastomers or molded polyurethane.

• Impeller prole is designed to minimize absorbed power.

High recovery CISA otation columns

CISA columns are establishing a new standard in column cell tech-

nology. Their unique sparger design consists of in-line static mixers

and recycling of tailings slurry. High shear conditions within the stat-

ic mixers produces ne, uniform air bubbles. This maximizes bubble

surface area ux in the collection zone and thus increases mineral

recovery.Numerous sparger retrot applications demonstrated 20 to 50%

increase in recovery in comparison of

conventional (air-only) sparger systems. Column cell design includes

ecient wash water distribution system, internal launders and other

features to produce high-grade concentrates.

The RCS otation machine is designed to give maximum exibility inlay-out planning.

CISA otation columns integrate leading-edge sparger technology.




Metso has a long tradition in magnetic separation.Already in the end of the 19th century the rst

magnetic separator was manufactured.

Low intensity magnetic separators

Metso’s LIMS, Low Intensity Magnetic Separators, recover

ferro-magnetic ores to produce pre-concentrates or concentrates.

The separators are available with three dierent tank designs using a

common magnetic drum assembly. Two of the tanks are designed to

enable easy multi-stage erection.

The magnetic system allows for very high loading with excellent

selectivity at highest recovery, which reduces the number of units

required. Fewer machines means less maintenance, lower capital and

operating costs.For dry material, around 20 mm and coarser the belt drum type

of separator, BSS or BSA, is preferred. For dry material ner than

20 mm the dust house enclosed drum separator, model DS,

is re commended.

Finer material is in almost all applications preferred to be processed

in water. Also for the wet processing there are a number of models

to choose from to suit the various requirements.

The concurrent, CC, and counter-rotation, CR, models are mostly

selected for processing of ore at the feed end of the concentration

circuit.

For production of the nal concentrate the counter-current, CTC,

model is the most ecient and mostly used model for producinghigh grade products.

For recovery of e.g. magnetite and ferro-silicon in dense media

separation processes special models, DM and CR, are designed to

provide highest possible recovery of the media.

For all wet processing separators the magnet system is selected to

achieve best performance in each individual case.

High gradient magnetic separators

Metso’s HGMS, High Gradient Magnetic Separators, recover ferro-

magnetic and para-magnetic material from ore slurries. The separa-

tors are designed around the unique magnetic system providing

magnetic elds up to 2T (20 000 Gauss).

The separator handles particle sizes from 0,1 µm up to 1 mm and

due to the excellent control parameters the metallurgical perfor-

mance is superior. The cyclic HGMS is best suited for material with up

to about 5 % magnetically produced fractions. With no moving parts

except for actuated valves handling controlled slurry velocities the

maintenance cost is extremely low.

High gradient magnetic separators are available in cyclic design with

process vessel diameters from 220 mm to 3 050 mm and in continu-

ous design with matrix ring mean diameters 1 200 mm, 1 850 mm,

2 500 mm and 3 500 mm.

Sedimentation equipment

The feed distribution system and inclined plate package design givesthe spiral dewaterer an outstanding separation capability.

Installation in LKAB, Kiruna, Sweden - 1000 m below ground.

Spiral dewaterer SDC - NEW DESIGN!

Metso’s dewaterer consists basically of an open

trough with arrangements for collection of theproducts.

The new spiral dewater SDC is designed with partdimensions suitable for container freight and with aself supporting tank.

The inlet ow is evenly spread out by means of a feed distributor.

Coarse material settles and is continuously removed by means of the

transport spiral. The material will be dewatered by drainage in the

upper part of the spiral before discharge.

Features• The water in the sedimentation tank is reclaimed and sent back tothe process again

• Solids are removed by and dewatered in the discharge spiral andcan be sent to recycling if this is considered of value

• Curved plates with integrated anges

• Rolled proles in high strength steel.

• Laser cut details ready with bolt holes and welding preparation.

• Part dimensions suitable for 40’ container transport

• Bolted sections

Beneits

• Lighter• New lamella pack design

• Assembly and installation friendly

• Fewer components

• Easier shipping

• Self supporting

• High strength

• No closed proles

• Short installation time

Typical installations:

Washing euents from the steel industry with high ows and a lowto moderate content of well dened solids like mill scales and slag isproven optimal for the spiral dewaterer.

For industrial dewatering applications settling areas from 8 m2 to

200 m2. Flow Rates up to 1 500 m3 /h.

Inclined plate settlers IPS

Metso’s IPS uses well proven lamella technology

principle to maximize the settling area for any avail-able oor area given.In this way, the size and cost of the gravity settlercan be minimised by matching the thickening andclarifying requirements more closely.

The two basic criteria for gravity settling equipment are good clarityof the overow liquid and maximum density of the underow solidsdischarge.

The area needed to clarify a suspension is often greater than thatneeded for thickening. This means that by conventional clariers the

lower section with rakes and drive mechanism often is oversized. TheMetso IPS is available as pre-fabricated units up to 500 m2 settling area and as combi type up to 5 250 m2, the latter in 24 m dia.tank.

As particles get ner the resistance against remov-ing water increases. Gravity dewatering can no

longer be used, pressure has to be used.By creating a dierential pressure Dp across a cakeof solids, liquid can be removed by

Compression

“Dewatering by compression means replacing the liquid in a cake

with particles”.

For tube presses either compression or a combination of compres-

sion and air purge is used. Similarily by the same method, cake

washing is possible on the tube press. This is known as displacement

washing where liquid is forced through the lter cake by hydraulic

pressure causing the remaining natural liquid to be displaced by the

incoming wash liquid.

For vertical plate pressure lters either compression or a combination

of compression and air through-blow is used. For vacuum lters air

through blow is used.

Vertical plate pressure flter VPA

The pressure lter model VPA is of “mediumpressure” type operating in the pressure range of 6-10 bar.

The machine mainly is based on the “air through-blow” dewatering

concept, whereby water is displaced by air as it passes through a

lter cake.


Filtration of metallic minerals, industrial minerals, coal and tai lings.

Tube press

The tube press is a membrane type lter pressdesigned in cylindrical format and capable of operating at high ltration pressures up to 100 bar.

The use of these high pressures enables a higher degree of separa-

tion of the liquid and solid phases.

The tube press is suitable or applications:

• Where the process requires very low cake moisture e.g. smelters

& driers

• Where cake handleability is critical. e.g. underground slimes

• Where ltrate is a valued product

• Where cake transport costs are signicant

• Where cake is to be disposed of to landll

Almost without exception, the equipment providedby Metso becomes part of a system.

The system may be a wet grinding circuit or a com-plete iron ore concentration plant with a pelletizingsystem. At either extreme, Metso has the capabilityto provide a complete system to our customers.

An optimized plant

A system is designed to take an ore, mineral or waste material from

one stage and turn it into a value added product one, two or more

stages later. How this is done, how many steps and what equipment

is used determines how well optimized a plant is.

We start from the creation of a process owsheet. Key parts of the

design may be tested in one of Metso’s test centers to verify equip-ment sizes. The nal owsheet will provide the lowest total cost of

operation.

Technical expertise

Metso has equipment design experience going back more than 100

years through our predecessor companies. In designing a system, we
