ternative process would be useful for recovering both copper and gold from such a low-grade concentrate. Cyanide–ammonia leaching of Telfer flotation tailings has been carried out by Muir et al. (1991) for 24 h with 0.3 M NH 3/0.1 M (NH 4) 2SO 4. This process extracted 82% Cu and no gold, followed by subsequent cyanidation of the washed leach

Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...

circuit where pyrite is depressed, and copper is concentrated to produce a copper concentrate for sale to smelters. Pyrite is then re-activated and concentrated to produce a pyrite concentrate that is then re-ground and fed to a cyanidation leaching process. Products include gold doré and copper concentrate.

Processing, smelting and refining gold World Gold Council

The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.
