ore dressing and extracting gold

Gold dressing process - Jinpeng Mining

Gold content is very low in ore. To extract gold, need crush and grind ore and use mineral processing to pre concentrate or separate gold. For gold dressing, the gravity separation, flotation and cyaniding are widely used. The CIL are widely used in Africa.
