Changes in metal prices and mine output over recent years have required the Copper Concentrator of Mount Isa Mines to operate at annual tonnage rates varying from million to million tonnes. Several circuit combinations were operated during this period utilising up to two semiautogenous grinding (SAG) mills and up to two ball mills. The aim was to maximise grinding efficiency and keep ...

Autogenous grinding is favored when the ore is quite competent and a fine grind is required. Semiautogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency. Figure 2 shows a typical conventional crushinggrinding circuit with three stages of crushing followed by ball mills or ...

Mining has been attempted at different times on the deposits in each region. Most of the state's small production has been from the Van HornAllamoore mining district, whereas only small shipments of copper have been reported from the North Texas and Llano regions. The last reported copper production was eighteen tons in 1952, valued at 8,712.
