In this work, we employed pulsating high-gradient magnetic separation (PHGMS) with highly magnetic induction (1.8T) to separate chalcopyrite and talc, and found that the PHGMS achieves a good separation of chalcopyrite from talc. But the chalcopyrite recovery decreased with the decrease of its particle size, and thus surface …

Pulsating high-gradient magnetic separation (PHGMS), as an effective and environment-friendly separation method, may separate chalcopyrite from talc, as chalcopyrite has a much larger magnetic susceptibility (0.84 × 10 −6 m 3 /kg) than that of talc (0.18 × 10 −6 m 3 /kg) (Liu, 1994). However, until today the feasibility of chalcopyrite ...
