tin processing - Mining and concentrating | Britannica

The principle of tin smelting is the chemical reduction of tin oxide by heating with carbon to produce tin metal and carbon dioxide gas. In practice, the furnace feed contains the tin oxide concentrate, carbon in the form of anthracite coal or coke, and limestone to act as a flux and a slag-producing agent. In a typical reverberatory process ...
