Copper Process Flowsheet Example
A simplified schematic drawing of copper flotation flowsheet. Run-of-mine open pit ore will be crushed in a gyratory crusher. The crushed ore will be processed by means of semi-autogenous and ball mill grinding followed by rougher flotation, regrind, cleaner flotation, and dewatering to produce copper concentrate. The concentrate will …
Crushing Plant Flowsheet & Design-Layout
In some copper concentrators, the mill feed is all passing 13MM(½"), using three stages of crushing and 14MM (9/16″) square openings on the closed circuit screens. It was felt by some that crushing to this fine size is only possible if the ore is friable and is relatively soft in comparison to the harder ores.
