Treatment of a Copper Nickel Ore in Xinjiang by Flotation- Magnetic Separation Combined Process
-
Abstract
A copper nickel sulfide ore in Xinjiang is taken as the research object, the combined process of copper selective flotation-magnetic separation of copper concentrate-copper/nickel bulk flotation of tailings for selective flotation was adopted to finally obtain a copper concentrate with Cu grade of 25.43%, recovery of 52.08%, Ni grade of 0.19%, MgO content of 2.32% and a copper nickel mixed concentrate with nickel grade of 3.57%, recovery of 81.55% and copper content of 2.53%; The total recovery of copper and nickel in the whole process is 90.77% and 82.10%. The results show that the process has the advantages of high grade of copper concentrate, low nickel loss rate and high copper nickel recovery rate.
