Key-words Electrorefine, anode slime, copper. Abstract Copper sulphides Concentrates, from the flotation process of copper primary ore contain, commonly, small amounts of precious metals, such as gold and silver. During the smelting process of those concentrate all gold and silver are practically in the blister copper, which is cast into anodes.

The flotation effect of refractory copper-sulfur ore containing secondary copper minerals is better than that with butyl xanthate, but its selectivity is worse. Aerofloat Aerofloat has a weak collection capacity and slow flotation speed for sulphide minerals, but its selectivity is better than that of xanthate collectors.

Jan 01, 2019018332Therefore, the application of flotation in copper oxide ore has attracted extensive attention 72269. The flotation of copper oxide can be mainly divided into direct flotation and sulphidizing flotation. The collectors for direct flotation are fatty acids, fatty amine, petroleum sulfonate and hydroximic acids 10,11.

Lime is used extensively in the recovery of gold and silver. Ores, either run-of-mine, milled, autoclaved or roasted, are combined with lime and a cyanide solution. The cyanide dissolves the gold and silver. Lime maintains proper pH in the cyanide solution, keeping it in the liquid phase and preventing the formation of hydrogen cyanide gas and its loss into the atmosphere.
