, and the dispersive mechanism of sodium hexametaphosphate was studied. The results of tests on artificial mixed mineral show that the hetero-coagulation between pentlandite and serpentine decreases the flotation recovery of pentlandite, the sodium hexametaphosphate can fulfil the flotation separation of pentlandite and serpentine by promoting the dispersion of artificial mixed mineral. The flotation results......
