COMPARATIVE RESULTS OF COPPER FLOTATION FROM …

Production of copper concentrate by flotation of smelter slag has started in 2001. Flotation concentrate goes to the Copepr Smelter once more for production of cop-per cathodes and the rough flotation tailings go to the flotation tailing dump. Copper recoveries in the flotation process of smelter slag reaches the value of about 45- 50%.

Copper processing

In the flotation process, the finely ground ore, mixed with water and special reagents, is agitated by mechanical and pneumatic devices. These produce air bubbles in the ore-water mixture, or slurry. The reagents provide an attraction between the surface of the copper minerals and the air bubbles. As the bubbles rise to the surface, they carry ...

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 ...
