LEAD INDUSTRY PROFILE - ila-lead.org

involves the following process steps: Smelting - reacting the lead rich mineral with other ingredients, to yield impure metallic lead. This is traditionally done in two stages: roasting in air, turning the lead concentrate (usually lead sulphide) into lead oxide; heating the lead oxide in a blast furnace with coke to yield metallic lead.
