Upcoming Courses

  • Copper SX-EW Course in Zambia - Hydrometallurgy

    copper sx ew





    Solvent extraction-electrowinning continues to transfor m the performance of copperoperations. This 4-day course is designed to provide technical staff with the knowledge, skills and insight required to understand copper solvent extraction and electrowinning, to improve plant operations, and to improve control of operations.
    Attendees will practice the principles of their learning through case studies and discussion groups, using specific practical examples.

Current and Recently Completed Projects


Process engineering study with options for a platinum refinery

Our brief was to develop the flowsheets and mass balances (metal recoveries and volumes), and calculate the capital and operating costs for five different flowsheet options for a platinum-group metals refinery. The client was under pressure, and the project was completed in record time.

Zinc recovery improvement on a flotation plant

Our brief was to improve the recovery of zinc on a plant. We used our methodology based on the theory of constraints to determine the best course of action, and achieved a measureable improvement in recovery by using a combination of control and process changes.

Blast optimisation study

Our brief was to develop a methodology for blast optimisation, which is also called mine-to-mill optimization. We surveyed previous case studies, distilled the essential steps and recommended the required methodology.

  • Minerals Engineering International - Copper SX Workshop
    Minerals Engineering International - Copper SX Workshop

    Some of the Copperbelt's top metallurgical minds converged on Kitwe for a copper solvent extraction and electrowinning workshop to learn, discourse and share operational experiences from across Zambia and the DRC.

    Offered by South African metallurgical consultancy, CM Solutions, the focus of the workshop was professional development and exposure to operational knowledge from around the world.

    The workshop was developed and presented by Dr Kathy Sole and Dr Frank Crundwell in response to a need for knowledge exchange in this highly specialised area of hydrometallurgy. "We were very lucky to have the calibre of a world class expert in Dr Sole leading the discussions," says Dr Crundwell, "which combined with the expertise of the delegates, and their willingness to engage, ensured in a lively interactive forum with very deep discussions on how to improve operations."...
