| Abstract: |
| The electroflotation action of galena pretreated under external potential from -3000mV to 2400mV, with current from 0 mA to 8.06mA, is investigated. The results show that anode treatment can improve the flotability of galena at lower potential. It plays an obvious depression role and reduces flotation pH range of galena at higher potential. On the other hand, cathode treatment can improve the flotability of galena and widen its flotation pH range, which is related with the function of polarization on reagents. The flotation features resulted from electrochemical treatment can be used for separation of galena from other sulphide minerals. |
