  • QSL Process for Smelting Lead Sulfides

    As in conventional lead smelting, the gangue minerals contained in the raw materials are separated from the molten metal in the form of a fluid siliceous slag. Instead of two separate steps of sintering and blasting in a furnace, the QSL Process is a onestep process of continuous smelting of the charge, with the resulting pellets directly fed to the oxidation and reduction zones of the reactor.
