Abstract: Based on the process mineralogical of the platinum-copper-nickel ore, the condition experiments of grinding fineness, pH adjusting agent type and dosage and some other experiments were carried out.The results show that with the branch flotation process, nickel concentrate with the grade of 3.17%, recovery of 43.49% is obtained.Meanwhile, Cu, Co, Pt, Pd are enriched to some degree and comprehensively utilized with nickel concentrates.
