The crushed copper ore (containing for example 0.75 Cu and 0.015 Mo) is fed to the grinding circuit where water is added and the ore is ground to the proper size. Lime and an oil for collecting molybdenum are usually added in the grinding circuit. A copper collector may also be added at this point. The pulp progresses to the flotation cells.

Ore is stockpiled (1) at the processing plant and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3) the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.
