Lead-Bismuth Flotation - Mineral Processing Metallurgy

Feb 28, 2016  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. So, applying the lead-copper separation technique is possible separate bismuth

Secondly, the flotation recovery of synthetically prepared Pd-Bi-Te was compared with that of chalcopyrite (a typical fast-floating mineral) and pyrrhotite (a typical slow-floating mineral), with microflotation tests. These indicated Pd-Bi-Te to be a fast-floater with flotation rates exceeding that of chalcopyrite. Predicted flotation rate ...
