2014-10-1  In the case of the Minix strong-base resin, there is the additional advantage of excellent selectivity for gold over copper. At Gedabek, where the Cu/Au ratio in the PLS is about 600–700 (see Table 3), the loaded Minix resin has a Cu/Au ratio of between 1 and 2, demonstrating a selectivity ratio for gold over copper of 300–700. After more than four years of operation, there is no significant resin

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
