As in most lead-zinc flotation operations, lead is separated first, followed by the zinc flotation stage. Due to the nature of the ore, lead minerals are frequently released from their gangue in coarse sizes, while zinc minerals need comparatively more grinding to produce the appropriate degree of liberation from accompanying gangue …

Lead and zinc mainly exist in the form of sulfide ore. At present, it is mainly obtained from lead-zinc sulfide ore [3]. Flotation, which is based on the differences in hydrophobicity of minerals, is an effectively and commonly used method for separating sphalerite (ZnS) and galena (PbS) minerals from lead–zinc ore [4], [5].
