60 Centuries of Copper: The Flotation Process

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 ...

Copper Flotation - Elmhurst University

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 ...

Development of copper recovery process from flotation tailings

Jun 15, 2018  The total copper recovered from its ore through flotation process is about 56% [6,18], which indicates that the flotation tailings still contain valuable copper components such as chalcopyrite. In addition, old flotation tailings sometimes have a higher copper grade (0.2–0.4%) than that of low‒grade ores (0.2‒0.3%).

某次生铜型高硫铜铅锌矿浮选工艺研究-Study on the Flotation Process of Copper

Abstract:There are some pyrite and secondary copper minerals in a copper-lead-zinc mine. Because of this, sphalerite and pyrite are comparably hard to be depressed in the copper-lead flotation process, which worsened the flotation indexes. Therefore, we have carried out experimental research on the inhibitors of these two minerals.

Explain froth flotation process of copper pyrites.

Answer. Copper is extracted from copper pyrites by froth flotation process. Froth flotation method is used to separate particles based on the differences in the ability of air bubbles to selectively attach to specific mineral surfaces in a mineral-water slurry. A finely crushed ore is suspended in water and a blast of air is passed through the ...
