Lead Ore / Lead Concentrate Smelting, Manufacturing

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 Lead is then cooled in stages which cause the lighter impurities (dross) to rise to the surface where they can be removed.
