How To Sservice A Copper Flotation

Apr 05, 2021

The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to give a basic pH, pine oil (yes, it comes from trees -- a by-product of paper mills) to make bubbles, an alcohol to strengthen the bubbles, and a

    Sep 24, 2018 The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the

Cyanide and lime have weaker inhibition on them, so a large amount of lime can be added to inhibit pyrite in the separation of copper and sulfur without seriously affecting the floatability of copper minerals
