Gold Metallurgy & Leaching in Cyanicides

Cyanidation as applied to ordinary gold and silver ores is a relatively simple process. When cyanicides {cyanide-consuming elements) are encountered in small amounts in the treatment of such ores, the various schemes already discussed, such as use of a lead salt or wasting barren solution, can usually be resorted to and successful operation maintained.

Mastering Oxidized Gold Ore Processing Techniques

Oxidized gold ores are relatively easier to treat using cyanide leaching than the sulfide ores because the oxidation process reduces the size of the sulfide matrix and liberates the gold particles.

Having some arsenopyrite in your gold ore sample does not insure a full refractory gold processes is needed for recovery. The presence of arsenopyrite and heavy sulphides just tells a component of fraction of the gold extraction process might have a refractory response. ... was added to the gold-silver bearing solutions to monitor the extent of ...

A systematic review of sustainable gold extraction from raw ores …

Gold flotation is widely used in the case of refractory ores, in which small-sized gold particles, locked within sulfide minerals, are recovered through flotation of gold-bearing minerals (Marsden and House, 2006). It is also an effective means for separating free gold from silicate particles present in ore.
