Simulation in mineral processing history, present CORE
Mineral processing models have been discussed for many years but it was not untilputers became available about 1960 that serious attempts at circuit simulation could be carried out. Even then the work was primarily academic until PCs could be used by engineers in plants and design offices in the mid 1980s, Since then simulation has

Mount Isa Lead, Zinc and Silver Mine Mining Technology
In 1970, MIM Holdings succeeded Mount Isa Mines but, while diversifying in the 1970s and 1980s, management seemingly neglected Mount Isa. Revitalisation started in the late 1980s. The rising cost of processing Australian intermediates led MIM to withdraw first from copper and then lead zinc smelting activities in Europe. These, plus improvements at MIMs coal operations, encouraged Xstrata
