·processing ventures wherever feasibility studies support such a pattern In the various sub systems and unit operations the following scenario is likely to emerge with respect to plant designs a primary Crushing Systems Where large scale mining operations are envisaged primary crushing plants may have to be located as close to the pit
·The crushing plants like any other production process are greatly affected by changes over time since it is a continuous process where equipment is subjected to variations
A research group now known as the Julius Kruttschnitt Mineral Research Centre at the University of Queensland has been working since 1962 on the simulation optimization and control of mineral treatment processes The initial work was on the grinding and classification processes This work has been very successful in the optimization Lynch et al 1967 and control Draper et al
·Copper concentrate CuFeS 2 is fed into the furnace along with a flux of silica sand SiO 2 and oxygen O 2 The flux is used to control the chemistry of the slag In particular it causes the iron Fe in the copper concentrate to accumulate in the slag phase while the copper Cu accumulates in the matte phase Copper Concentrate
·Copper directly underpins society s planned transition to a lifestyle powered by renewable electricity Electric vehicles contain between 4 and 8 times more copper than petrol/diesel alternatives; renewables use around 5 times more copper than conventional power systems2 Factors such as these justify predictions of a copper supply shortfall
