Advances in depressants used for pyrite flotation separation …
3.1 Coal pyrite depressants. Although the contact angle is smaller and the induction time of coal pyrite is longer than those of coal (Qi et al. 2019), coal pyrite has better floatability than ore pyrite due to the doping of C atoms.Efficient depressants are needed to inhibit the floatability of pyrite in the flotation separation of coal and pyrite.
