After the retort process, a silica and borax flux is added to the gold in a smelting induction furnace. It is from this induction furnace that gold dore' bars are poured. The slag produced from this smelting has between 50 to 100 ounces of gold per ton and is collected and sent to the ball mill where it is crushed and recycled into the CIL circuit.

It is then sent to three identical ball mills, which are in closed circuit with hydrocyclones. The slurry is thickened and fed to the leach tank circuit for conventional cyanidation and carboninpulp processing to extract gold. The final product is gold / silver doré bars. The tailings are pumped to a tailings impoundment facility following thickening and detoxifiion, which reduces ...
