Effect of H2O2 on the Separation of MoBiContaining Ore ...

Hydrogen peroxide (H2O2) is a strong oxidizer that causes nonselective oxidation of sulfide minerals, and its influence on bismuth sulfide ores is not welldocumented. In this study, H2O2 was proposed as an alternative bismuthinite depressant, and its effect on a MoBicontaining ore was intensively investigated by batch flotation tests.

Thus, the copper concentrate will not have penalties for bismuth. Ideally, the bismuth content must be less than 1000 ppm. Considering the fact that lead and bismuth are very close in the periodic table (number atomic: 82 Pb, 83 Bi), they can have similar behaviour during flotation. It means that collection and depression is very similar for both.
