Erdaohe silver zinc mine 500t/d oxidation ore beneficiation project -- Zhalantun City Guosen Mining Co., Ltd.

The project is located in the mining area of the Greater Hinggan Mountains, a high-cold area, the annual temperature of 35℃, the temperature of -45℃, the annual average temperature of -4 ℃, the altitude (1000 meters). The proportion of ore is 2.957t/m³, the mud content is 15%; Processing capacity :500t/t, flotation feed concentration: about 35%, magic ore fineness -200 mesh 80%, zinc oxide tailings 1 concentration: about 35%, zinc oxide tailings 2 concentration: about 15%; Temperature: about 25°C; The beneficiation process of separating sulfide tailings by sulfide flotation and zinc-sulfur mixed flotation followed by priority floating of oxide tailings by cyclone desliming (-10um slime) -desliming tailings was adopted.
