Lead Ore / Lead Concentrate Smelting, Manufacturing

The Froth flotation process separates the Lead and other minerals from the waste rock (tailings) to form a concentrate. The concentrate, which can range from 50% to 60% Lead, is dried and then treated using pyrometallurgy. The concentrate is sintered before being smelted in to produce a 97% Lead concentrate.

The concentrate is sintered before being smelted in to produce a 97% Lead concentrate. The Lead is then cooled in stages which cause the lighter impurities (dross) to rise to the surface where they can be removed. The molten Lead bullion is then refined by additional smelting with air being passed over the Lead to form a slag layer containing any remaining impurities and producing 99.9% pure Lead.
