Galena
Lead occurs as galena (PbS), cerisite (PbCO3 ), and anglesite (PbSO 4). Galena is the most common. Lead ores are usually roasted and then reduced in a blast furnace with coke. Purification is carried out by adding zinc, which removes silver (Parkes process), or by electrolysis in a solution of lead hexafluorosilicate and hexafluorosilicic acid ...

Lead Zinc Sulfide Separation by Sequential Flotation
When grinding the average lead and zinc ore to minus 48 or 65 mesh, the lead mineral particles overflowing the classifier will, for the most part, be all minus 200 mesh. This is due to the difference in gravity between galena (SG 7.4 – 7.6) and the gangue (quartz sp. gr. 2.65, calcite 2.7).
