A refractory gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic carbon, or both. Sulfide minerals are impermeable minerals that occlude gold particles, making it difficult for the leach s

Gold can be freed from these ores or concentrates by treating them with various oxidizing processes. Themon method is to roast gold bearing minerals at temperatures of 450° to 750° C 840° to 1,380° F to destroy the interfering sulfides.

The invention relates to a method for recovering gold from a sulphidic concentrate, particularly one containing arsenopyrite and/or pyrite, hydro metallurgically. The concentrate is first subjected to leaching with a concentrated solution of alkali chloride and copper II chloride, by means of which the copper minerals and some of the gold in the concentrate are made to dissolve.
