Selective depression of chalcopyrite by 2-mercapto-5-benzimidazolesulfonic acid sodium salt for the flotation separation of Cu–Mo sulfides

The flotation separation of chalcopyrite from molybdenite is hindered by their comparable floatability in the presence of collectors. In this work, 2-mercapto-5-benzimidazolesulfonic acid sodium salt (MBS) was proposed as a selective chalcopyrite depressant in Cu–Mo flotation usi...
