Know More
In copper ore the addition of concentrated acid in the agglomeration step results in a very aggressive high temperature attack of copper minerals which is not possible once in the heap Similarly gold ores are dosed with 1000 to 2000ppm cyanide solution which speeds up the diffusion controlled reactions by increasing the rate of lixivant...

Eliminating Copper from Gold Ore
Know More
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...
