The main recovering element in a ore is gold , and gold mineral is micro particle . poisonous ele-ment in a ore is less . The technology of one coarse grinding and two roughing flotation Followed by three cleanings .This technology is simple and effective . Flotation gold concentrate grade is 122 g/t and the gold recovery rate 92 .56% on the condition of crude gold grade being 19 .56g/t . This technological process pro-vides a technical basis for the development of the mine .
