Gold-copper ores - ScienceDirect

Jan 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, which contains levels of gold mineralization. This would be uneconomic to mine for its gold content, but the gold provides a significant opportunity value.

Eliminating Copper from Gold Ore

Mar 19, 2017  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 ...

Leaching Stubborn Oxidized Gold Ores That Contain Copper ...

Jan 21, 2016  This article is devoted to the leaching of gold from copper-bearing oxidized stubborn gold ores in the Tarror deposit. The high copper content of the ores makes it difficult to extract gold from them by direct cyanidation. An analysis of the literature data indicated that ammoniacal leaching might be one solution to this problem. It is shown that the use of ammonia compounds in the
