    Lead, is dried and then treated using pyrometallurgy. The concentrate is sintered before being smelted in to produce a 97% Lead concentrate. The Lead is then cooled in stages which causes the lighter impurites (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.
