  • Cassiterite

    In the conventional reverberatory furnace process, cassiterite (SnO 2) is reduced to tin metal by heating with carbon at 1200–1300°C (2192–2372°F).Tin concentrate is smelted to resmelted slag for additional tin recovery. The furnace charge consists of tin ore (cassiterite), a carbon reducing agent (coke), and limestone and silica fluxes.
