Eliminating Copper from Gold Ore

11/10/2015 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

Gold-copper ores ScienceDirect

01/01/2005 The association of gold and copper mineralization in commercially viable ore is a common occurrence. At one end of the spectrum is the predominantly copper ore that contains levels of gold mineralization. This would be uneconomic to mine for its gold content, but the gold provides a significant opportunity value.

Gold Extraction from Different Types of Ore

10/01/2020 Copper-bearing sulfide gold ore refers to some form of copper ore and gold symbiosis in the gold ore, and coexists with pyrite. For copper-bearing sulfide gold extraction, we can enrich gold in copper concentrate by flotation, and then comprehensively recover copper and gold by smelting.

The leaching and adsorption behaviour of gold ores

gold was completely extracted by cyanide alone. The flotation feed and copper concentrate showed an enhancement in gold extraction due to the activated carbon adsorbing gold that would otherwise have been preg-robbed.
