Our laboratories undertake extractive metallurgical testwork using all common processes such as gravity concentration, pulp or heap leaching and flotation, and some not-so-common processes such as pressure attrition leaching, and hybrid gravity recovery/heap leaching for our clients.

Our emphasis is on enhanced gravity recovery, both semi-batch and continuous. Our philosophy - if it can be done with water and power alone, why introduce costly chemistry? We pride ourselves on innovation, and on going beyond where gravity recovery has gone before.

Where chemistry is necessary, however, we do undertake leaching, flotation or other process tests, either independently, in comparison with gravity recovery, or as a peripheral or downstream process with gravity recovery.

We work closely with Knelson Gravity Solutions - acknowledged world leader in enhanced gravity recovery equipment - and provide valuable R&D services to the company. Both of our laboratories are equipped with the latest Knelson technology, including KC-CVD Continuous Variable Discharge pilot plants.

We also cater for more traditional gravity methods such as spirals, shaking tables and mineral jigs.

Our gravity emphasis does not mean gold only. It also extends to platinum group elements (the largest installation of Knelson Concentrators in the world is on platinum), industrial minerals such as chromite, by-product precious metals from base metals, and even base metal sulphides. We cater for all minerals - whatever the process.
