BEHAVIORS OF Sb,Sn AND As IN LEACHING AND ELECTROWINNING FROM JAMESONITE CONCENTRATE

The separating efficiency of Sb from As and Sn in jamesonite concentrate could be improved by changing the composition of leaching solution and other conditions.The related kinetic parameters of electrode reaction were evaluated under discussion on the form of complex ion AsS_3~(3-)in extract and the reduction at amalgam electrode.It was also discussed about the ef- fect of eoncentration of Na_2S and SbS_3~(3-)in solution on the current efficiency of SnS_4~(4-) reduction.
