Characterizing gold in refractory sulfide gold ores and Çöpler Oxide Ore

Gold is present in refractory sulfide gold ores mainly in arsenian pyrite and arsenopyrite where it occurs in both the chemically bonded state and as nano size grains of metallic gold During roasting or pressure oxidation the sulfide matrix is destroyed and essentially all the gold is converted to the metallic form The liberated gold is readily dissolved in conventional cyanide media The Çöpler Gold Mine is operated by Alacer Gold and is currently an open pit heap leach operation that is producing gold from oxide ore The Çöpler orebody also contains refractory sulfide ore that requires a different processing solution than heap leaching to extract the gold In June a Definitive Feasibility Study was completed and determined that the treatment of the sulfide ore
