Equipment For Mixing Gold Ore And Cyanide
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.Contact Supplier
