Cassiterite - an overview | ScienceDirect Topics

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.

Extraction of metal from the ore cassiterite involves

Tin is obtained by reducing the ore cassiterite with coal in a reverberatory furnace; Limestone is added to produce a slag with the impurities, which can be separated. S n O 2 + 2 C S n + 2 C O. Crude tin so obtained is contaminated with iron, copper, lead and other metals. It is, therefore, remelted on an inclined furnace. The process is ...

Tin processing - Mining and concentrating | Britannica

Tin processing - Tin processing - Mining and concentrating: Vein deposits, such as those in Bolivia and the United Kingdom, usually occur in granite formations and are recovered by conventional underground hard-rock mining techniques. In deep mines, primary crushing equipment is usually located underground in order to reduce the ore to a manageable size before transportation to the surface.

Smelting - Cornwall Council

The reverberatory furnace used coal instead of charcoal. This meant the tin ore could be reduced just by using heat, so it was no longer mixed with and contaminated by the fuel. By the 19th century, most tin smelting was conducted in reverberatory furnaces, although the larger and more important blowing houses remained until the mid 1800s.
