Mining Geochemistry Services

About Us

Geochemic Ltd was established in September 2015 to offer comprehensive and cost

effective environmental geochemical consulting and laboratory services to the mining

industry.

We deliver this service through highly selective and efficient data collection and through

the utilisation of all existing data gathered by our clients. In this way we ensure that

sampling and analysis costs are kept to an absolute minimum whilst ensuring all

foreseeable risks are analysed and resolved through the generation of comprehensive

conceptual and predictive numerical models.

We have laboratory facilities for undertaking kinetic tests on mining wastes. These tests

include humidity cell tests (ASTM D 5744) which are commonly referred to as the industry

standard for assessment of the weathering of mining waste. By carrying out the kinetic

tests ourselves, we can be confident of the accuracy and precision of the results.

In the modern mining industry it is critical that nothing is left to chance. That is why we pride ourselves on being able to identify potential risks and solutions that others may have missed.

Our Laboratory Services

At Geochemic we have a well equipped laboratory facility designed specifically for

geochemical testing of mining waste materials. We can accommodate many types of

kinetic column leaching, oxygen consumption and attenuation tests including standard

ASTM D 5744 humidity cell tests. Our facility includes:

Stable laboratory temperature maintained at 20oC (± 2oC),

Elga-Option R-7 purified water system supplied by a Veolia. This system produces

ASTM Type II+ water (greater than 15 M ohm resistivity) exceeding the quality

requirements of the ASTM D 5744 standard methodology

Laboratory analytical facilities for the immediate analysis of parameters such as

pH, alkalinity and sulfate

On site preservation of samples and analysis externally for major and trace

elements at an ISO 17025 accredited laboratory

We offer testing as both a standalone package or in conjunction with our consulting services.

How to contact us

Geochemic is located at the edge of the historic South Wales coalfield in the town of

Abergavenny, United Kingdom.
