Abstract: The pyrrhotite , pentlandite and nickel pyrrhotite in a copper -nickel polymetallic ore were closely associated, and comparative tests were carried out applying a variety of mineral pro -cessing schemes .Finally a process of copper -nickel bulk flotation -flotation separation of copper and nickel from the bulk concentrate -bulk flotation tailings retreatment by magnetic separation was applied , outputting three concentrates .The copper concentrate contains 26 .14%Cu with a re-covery of 80.83%, and the content of Ni is 0.71%.The nickel concentrate contains 5.61% Ni with a recovery of 72.99%,and with a Cu content of 0.45%.The magnetic concentrate contains 1. 04%Ni with a recovery of 6 .84%.The study realizes effective recovery of valuable copper , nickel elements in the ore .
