Charmain Kruger has joined the CM Solutions team in a newly created role as Project Administrator to Frank Crundwell.  She was previously with Synntech, working exclusively with BHP’s Metalloys and is currently studying towards a National Diploma in Financial Accounting. When not keeping the CM Solutions project ship on course, she can be found working out in the gym.

All facets of leaching and dissolution, with best practice case studies from around the world, came under the spotlight recently when 23, mostly senior process engineers from South Africa, Namibia and the Democratic Republic of Congo, came together to gain insights and to beef up their skills at the annual CM Solutions Leaching Practice and Principles course in Johannesburg.

CM Solutions has launched a Facebook page for up to date information on the company and its team.

Electra Mining Day - Half Day Workshop - 18 SEPTEMBER 2014

A client has several concerns about the design of an autoclave. CM Solutions studied these concerns in detail. The mass transfer coefficient was calculated and compared with that which the agitator could deliver. The residence time in the autoclave was compared with the design flow rates, and the design flows were confirmed by calculating the energy balance for two limiting cases.

Frank Crundwell, from CM Solutions, presented a paper at ALTA 2010. The paper had the title “Optimization of exothermic pressure leaching systems”. The paper examined the effect of the type of cooling systems on the performance of the reactor. For example, cooling could be provided by quench, coils, flash recycle, amongst others. It was found that flash recycle significantly increases the performance of the autoclave.

CM Solutions was honoured to be involved again in the training of graduates in hydrometallurgy at Anglo Platinum. The delegates were asked to study the current operations and compare the operations with new process. They modelled both processes using Cycad Process™, and then studied a number of different scenarios. Changes in the mineralogy, feed rates of matte and solutions concentrations were examined. The models that the delegates developed will be used in the expansion project and by the plant metallurgists after the expansion is commissioned.

We are proud that Justin has joined our ranks! Justin, who joins us from TWP Projects, has worked in both design and production environments. He holds a BSc in Chemical Engineering from the University of the Witwatersrand, Johannesburg. His responsibility will be to add value to our clients through his work as a process consultant. Welcome Justin!

CM Solutions has completed a financial study of a joint venture between a number of parties in a BOO structure. The model clearly demonstrated that the success of the venture was dependent on several factors, such as receivable days.

CM Solutions was contracted to conduct part of the due diligence at a gold mine in Kazakhstan on behalf of a Swiss bank. The due diligence involved both the physical due diligence, and the NPV valuation of the asset.
