· 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 and copper too.
