Gold Sulfite
Sulphites of Gold, alkaline sulphites, or sulphur dioxide, which reduce gold trichloride easily, do not produce the same effect on a solution of an alkaline aurate. If sodium bisulphite is added to a boiling solution of sodium aurate (NaAuO2) a yellowish precipitate is formed, soluble in excess of sodium bisulphite, and consisting of a double sulphite of gold and sodium, or sodium auro ...
Sulphide Gold | Gekko
When gold is associated with sulphides, it can be either fully encapsulated by the sulphide particle or partially liberated, i.e. exposed on the edge of the sulphide mineral. Sulphide complex gold can occur in a wide range of particle sizes. Because cyanide cannot always leach sulphide-associated gold, regrinding the ore is typically required to expose the free gold for recovery by intensive leaching.

Heap leaching - Wikipedia
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of stone reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...
