Research on the Flotation of Low Grade Copper-Nickle Ore

Abstract:

Effect of grinding fineness and inhibitors on mixed flotation of low copper and nickel were studied and a new nickel inhibitor YS was used in the process of separation of copper and nickel. The results indicated that the high-quality mixed concentrate with the recoveries of Cu and Ni 76% and 65.6% and the grade of Cu and Ni were 4.66% and 4.3%, respectively, was got under the condition of sodium silicate (200 g/t), CMC (200 g/t), copper sulphate200 g/t, amyl xanthate 100 g/t and pine oil 30 g/t with the grinding fineness of-0.074mm80%. Then, Qualified Cu concentrate with the grade26.65% and recovery 55.62%, Qualified Ni concentrate with the grade26.65% and recovery 55.62%, respectively, were got by using the new nickel inhibitor YS in the separation flotation of copper and nickel.
