Floatation of Pyrite which be Pretreated by Electrochemical Ways under External Controlled Voltages

摘要：

The flotation of pyrite which be pretreated by electrochemical ways under external controlled voltages in different pH is explored. The floatability of pyrite is increased indistinctively after being pretreated in acidic and xanthate environment; Whereas, it is increased obviously between 400～800millivolt in alkaline and xanthate condition. The reason for higher recovery of pyrite is that oxidation reaction, which results in S0 and S02, takes place on its surface, and that ethyl xanthate is oxidized into dixanthogen. In the meantime, the kinetics and mechanism is also studied.
