gold recovery from tailings equipment

Gold Tailings Reprocessing Technology - xinhaiepc

Gold and silver recovery from gold tailings by CIP. All-slime cyanidation carbon pulp gold extraction technology can recover the gold and silver from the old gold tailings. Xinhai usually adopts the all-slime cyanidation + CIP in the gold extraction from old tailings. The gold tailings after cyanidation are treated by dry stacking.
