Equipment For Mixing Gold Ore And Cyanide

Sulphide Gold | Gekko

Sulphide Gold | Gekko

Because cyanide cannot always leach sulphide-associated gold, regrinding the ore is typically required to expose the free gold for recovery by intensive leaching. Critically, the size at which one can efficiently liberate gold from the host mineral of the particle will determine the process to use for optimal gold recovery.

Hard Rock Mining Gold and Silver Ore and processing it

In most gold ores, the final process to extract the tiniest gold particles is the use of cyanide to dissolve the gold. Cyanide, in the presence of oxygen actually dissolves both gold and silver. It is both efficient and inexpensive, so it is widely used in precious metal ore processing. Properly done, gravity concentration followed by flotation .
