Get PriceCopper Sulfide Ore About 80% of the world s copper from ore originates in Cu Fe S ores such as chalcopyrite CuFeS2 and chalcocite Cu2S The concentration of these minerals in an ore body is low Typical copper ores contain from 0 5% Cu open pit mines to 1 or 2% Cu underground mines
Get Pricealso limited to concentrate the nickel The mined ores 1 4% Ni are processed to upgrade the metal content with 10 20% Ni in the concentrates Thus the preconcentration of nickel ores is an important unit operation to upgrade the nickel before commencing any extraction steps Ni is mined from sulfide ores Nickel ferrolaterite and serpentine
Get PriceTo be applicable to this process the ores must contain copper minerals in sulfide form; as mineral such as Chalcocite Cu 2 S Chalcopyrite CuFeS 2 and Covellite CuS In the concentrating operations these minerals are separated from the gangue material of the ore that might contain as little as 0 5% copper to form a concentrate
