  • Copper Flotation Mineral Processing Metallurgy

    A Copper Flotation Flowsheet Because the copper in this type of ore usually assays only plus or minus 1% copper the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation.

    COMMINUTION AND SEPARATION30. The first step in separating copper from other minerals in ore mined by underground or open pit methods is comminution (pulverization) of the ore chunksessentially from boulders to grains of sand. (Mining is actually the first stage of size reduction accomplished with explosives.

  • Copper Mining and Processing Processing of Copper Ores

    The first steps of copper processing are the same for both ores mining and transporting. Copper mining is usually performed using openpit mining in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore boring machinery is used to drill holes into the hard rock and explosives are inserted into the drill holes to blast and break the rock.

    1.1.3.1 Openpit mining Openpit mining is a type of strip mining in which the ore deposit extends very deep in the ground necessitating the removal of layer upon layer of overburden and ore. In many cases logging of trees and clearcutting or burning of vegetation above the ore deposit may precede removal of the overburden. The
