| Abstract: | Research on the copper-nickel ore bearing-pyrrhotite and serpentine higher content. Lime and BK536 were used to depression pentlandite and BK521 were used to depression pyrrhotite.Adopt the process of copper and nickel bulk flotation - enhanced recovery of nickel, the locked-cycle test index is as following,copper grade is 31.25% and containing nickel with 0.53% of the copper concentrate, the total recovery of copper is 80.99%,nickel grade is 11.62% of the nickel concentrate, the recovery of nickel is 69.69%. |
