Don’t see what you need or are unsure about some of the services and associated requirements?

We understand that metallurgical testwork is not a one-size-fits-all or a pick-off-a-menu proposition, and so we are happy to help walk you through the process. Or you might know exactly what you want and just need some clarifications. No problem. Please contact us for further details.


Hydrometallurgical testwork

Process development & optimisation

ALS has created and invested in a state-of-the-art Hydrometallurgical Centre of Excellence (HCE). We have a dedicated, fully equipped facility covering an extensive range of bench and continuous testwork options for process flowsheet development, and unit operation testing. The HCE can accommodate a simple amenability leach test, progressing to scoping studies on master composites, right through to bankable feasibility studies encompassing comprehensive process optimisation and validation together with variability studies.

Capability & experience

Hydrometallurgy is really getting to the sharp end of processing, long past crushing rocks and handling slurry streams. The processes ALS uses are intricate and the chemistry extremely complex, and moreover, the safety implications of adding acid, pressure and high temperature are ramped up exponentially from upstream processing. Clients expect and need a laboratory team to be conversant in all matters to achieve their project goals. The integrated depth and breadth of technical services available to our professional staff means that testwork is carried out efficiently and safely with informed decisions made in a timely manner. We have access to expertise and developments at the cutting edge of metallurgical technology.
