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
My answer is to getting the gold free of copper, and it works for any alloy. 1. Raise the surface area/volume. Beat it until it is as thin as possible, or crush it and do your best to make dust/tiny fragments. 2. Put the whole of the sample into a...
