lead-bismuth flotation - 911 metallurgist

Feb 28, 2016 · The idea is separate lead and bismuth minerals from chalcopyrite by flotation. 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 …
