The other is to lower the limited level of sulphide minerals, which may increase the electronic density of mineral surface, as a results the unoccupied levels of xanthate are occupied by electrons, and dixanthogen is reduced, as the case of sodium humate. 二是有机抑制剂降低了矿物边缘能级,从而导致矿物表面电子密度增大,黄药空能级被电子占据,双黄药被还原。
The floatation mechanism of dixanthogen used as a metal collector is explained by the results of charge density calculation of the atoms in its molecule. 本文通过对原子电荷密度的计算,解释了复黄原酸作为金属捕收剂的作用机理。
Reducing behavior of electrochemistry for dixanthogen on the surface of stibnite 辉锑矿表面疏水产物&丁基双黄药的电化学还原行为
