Feb 01, 2005 The lead grade in the ore varies between 4% and 40% depending on the ore type. These lead minerals are sparingly soluble in sulfuric acid solution during zinc leach process. In the recovery of lead from leach residues, flotation is a common method. In the conventional hydrometallurgical processing of zinc, the first stage is lead flotation
