Coarse particle flotation applied to copper sulfide ores

Coarse particle flotation applied to copper sulfide ores

The largest source of copper supply worldwide comes from copper produced through flotation processes. It is estimated that more than 82% of primary copper production comes from concentration by flotation processes. In Peru, the latest mining megaprojects have been concentrator plants (Cerro Verde, Las Bambas, Constancia, Antapaccay, and so on).

Flotation ore dressing Britannica

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

Handbook of Flotation Reagents ScienceDirect

The bulk copper–lead flotation with depression of zinc followed by copper–lead separation and re-flotation of zinc is the most common practice in the treatment of copper–lead–zinc ores. About 90% of operating plants use this method. The bulk concentrate is usually contaminated with pyrite and zinc.

The cleaner stage consists of an 8-cell row, of the same type as rougher ...

60 Centuries of Copper The Flotation Process

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 ...
