2005-2-1 · The flotation tails which form the zinc concentrate goes to zinc electrowinning. Another possibility is to apply solvent extraction process, eliminating the lead flotation stage at the beginning, recovering lead minerals from the residues at the end, producing saleable lead concentrate, thus, reducing the size of the flotation unit.
Electrolytic flotation experiments under the same conditions as by dispersed-air flotation reveal higher recoveries of copper, lead and zinc. The electrolytically generated gas bubbles are finer than those employed in conventional flotation processes; they are more homogeneous in size and evenly dispersed over the flotation cell.
