Gold-Copper Ores - ScienceDirect

2016-1-1  For oxidized and transition copper–gold ores, it is difficult to obtain an acceptable copper concentrate. The two most common approaches are controlled potential sulfidization (CPS) and the fatty-acid flotation method (Phetla and Muzenda, 2010). The selected method is dictated by the nature of the mineral makeup of the gangue, which is often complex and can play a significant role in the overall

Eliminating Copper from Gold Ore - 911 Metallurgist

2015-10-11  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

A mechanism is proposed which involves the dissociation and precipitation of these metal-cyanide complexes, where the cyanide from the dissociation of the complex is used to leach gold from the ore. The stepwise dissociation of cyanide from copper-cyanide complexes can also be used to leach gold

[PDF] Gold Recovery from Copper-Rich Ores

There has been renewed global interest in the exploitation of historically marginal gold ore bodies, as a result of the recent steep rise in the gold price. The majority of these ores are complex and many of them contain significant amounts of copper minerals. The presence of copper causes a number of problems, including lower gold recoveries, increased cyanide consumption and increased ...
