2021-7-1  Prior flotation tests showed that tiopronin was a prospective copper depressant in Cu-Mo sulfide separation. With the purpose of further testing the selectivity ability of tiopronin, artificial mixed minerals were utilized for flotation. Fig. 4(a) illustrates the effect of tiopronin concentration on the flotation separation results. It can be observed that the desirable separation results were achieved when tiopronin was applied as copper
