Copper Flotation Mineral Processing & Metallurgy

2016-5-16  The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs, but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation.

60 Centuries of Copper: The Flotation Process

2021-7-19  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

Development of copper recovery process from flotation

2018-6-15  Generally, the flotation tailings are produced as a byproduct during the beneficiation of copper ore, namely froth flotation before the pyrometallurgical processes. According to the literature data, about 90–95% of the plant general tailings, i.e. flotation tailings and cleaning tailings, are produced from flotation process and represented as flotation tailings [ 6, 7 ]. They are treated by methods including cross valley or hillside dams, raised embankments/impoundments, dry‒stacking of thickened tailings on land, backfilling into abandoned open pit mines or underground mines, and direct disposal into rivers, lakes and the ocean (ocean surface and submarine tailings
