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.Web

(72%-74% Sn). In processing tin ore using a shaking table, valuable minerals and impurity minerals are separated based on differences in specific gravity, size and shape of the mineral. To get the recovery of valuable minerals (recovery) and optimal grades, it is strongly influenced by the separation variables of tin ore minerals.Web

Flotation is a cost-effective mineral processing method and is widely used to beneficiate sulphide minerals. Other methods, such as gravity concentration and magnetic separation [5], are also used to separate cassiterite from associated gangue minerals.
