摘要：
In the thermodynamics, for flotation separation of the Sb-As bulk concentrate system there is no potential extent using butyl xanthate as collector. However in the kinetics, there exists 150 mV in reducing potential of butyl dixanthogen on the surface of stibnite and arsenopyrite. In this paper, their reducing kinetic difference of electrochemistry was confirmed by pure mineral flotation under controlled potential, the artificial Sb-As bulk concentrate flotation separation and UV-spectrophotometic analysis. The electrochemical separation of Sb-As bulk concentrate has been carried out. qualified concentrate has been obtained. Sb-concentrate contains Sb 49.44 %, As 0.44 %, Sb-recovery is 87.83 % and As-concentrate contains As 10.96 %, As-recovery is 94.66 %.
