  • Learning from each other and from plants around the world’ key attraction for delegates at Leaching course.
    Learning from each other and from plants around the world’ key attraction for delegates at Leaching course.

    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.

  • Mass transfer and flash recycle rates in an autoclave

    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.

  • CM Solutions presents at the ALTA conference

    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.

  • Graduate training in hydrometallurgy

    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.
