Eliminating Copper from Gold Ore

When reviewing Methods of Eliminating Copper from Gold Ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation. Preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite, azurite and chrysocolla but these acids have but little effect on sulphide copper

In the oxidized zone of Rakha-Chapri Block of the Singhbhum Copper Belt, alteration of biotite, chlorite and muscovite extends down to ∼ 60 m. Below this level, these minerals are not altered, implying a supergene origin for the clay alteration products. The altered host-rock profile consists of an upper, predominantly kaolinitic zone and a lower illite-chlorite rich zone, with the clay

As the air bubbles that are generated in the bottom of the tank rise to the surface, copper-bearing minerals attach to the rising bubbles. The copper-rich froth at the top the tank is then skimmed off and taken to a thickening stage, which is followed by dewatering. The resulting copper concentrate typically contains around 30% copper.

A major risk of sulfide mining is the potential for acid mine drainage. When sulfide-bearing minerals are exposed to air and water they can break down, creating sulfuric acid. Once in motion, this acid leakage can persist indefinitely and wreak havoc on aquatic ecosystems. One need look no further than the Zortman-Landusky mines, a pair of
