Commercial copper production was declared on March 1, 2009, when copper concentrate inventory levels surpassed the 5,000 tonne shipping threshold. Increased zinc levels in the ore body, as it was continuously being mined, prompted the construction of a Cu/Zn separation circuit as extension of the previous flotation circuit.
The Copper Mountain Mine mill uses a simple processing flowsheet composed of primary and secondary crushing, and semi-autogenous ball mill, pebble crushing (SABC) grinding, followed by a sulphide rougher/cleaner flotation circuit. ROM ore is fed to a gyratory 60-in by 89-in primary crusher.
