Copper Process Flowsheet Example. A simplified schematic drawing of copper flotation flowsheet. Runofmine open pit ore will be crushed in a gyratory crusher. The crushed ore will be processed by means of semiautogenous and ball mill grinding followed by rougher flotation, regrind, cleaner flotation, and dewatering to produce copper concentrate.

After grinding, the mill discharge flowed into an agitating tank, which was used for adding 40g/t of Z 200 reagent and intensive pulp mixing before flotation. For copper flotation, one rougher flotation machine, two scavengers with adding 10 g/t of Z 200 and three cleaners with 400 g/t of lime were adopted.

The flowsheet of the Kevitsa flotation circuit is shown in Figure 1. Copper and nickel minerals are separated by sequential flotation. Copper is floated first, and the copper scavenger tails is the feed to nickel flotation. Finally, pyrrhotite and other remaining sulphurbearing minerals are floated and sent to the high sulphur tailings pond.
