Gold in ore of the project was the only recyclable element with a grade of 2.6 g/t.
Crushing and Washing Stage: It used cylinder screen to wash ore and the large pieces on the screen are crushed by a hammer crusher. Raw ore ≤150mm was crushed and washed to obtain a mineral sizeof ≤5mm with a concentration of about 35%, which was transported to the dip tank through alloy pump.
Pool Leaching Adsorption: Gold liquid was with about 40m³/h, which was transported to 3 adsorption columns by chemical pumps. Gold Intermediate and Poor liquid Adsorption Stage: After adsorption, the intermediate liquid entered the intermediate liquid tank and circulated through chemical pumps. The fully-absorbed poor liquid regularly got into the poor liquid tank and was discharged after removing cyanide ions.
Desorption Electrolysis: The gold-loaded carbon was processed by the desorption electrolysis system.
Activated Carbon Pickling Regeneration: Adopted the activated carbon pickling and regeneration system, equipped with united operation with desorption electrolysis. Smelting: After the smelting treatment, gold bullions with a purity higher than 80% were obtained.
