| Abstract: | To process a refractory pyrrhotite-rich copper-nickel sulfide ore with low content of copper and nickel and fine dissemination size of valuable minerals, a new type of high-efficient depressant for pyrrhotite mineral was developed and a novel technology of copper-nickel-sulfur mixed flotation and Ni-S flotation separation was proposed. The closed-circuit test on this new flowsheet with new depressant produced a copper-nickel bulk concentrate assaying 2.69% Cu and 7.54% Ni with a copper recovery of 77.52% and a nickel recovery of 77.87%, as well as a sulphur concentrate grading 34.25% S. |
