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 ...

Reverberatory Furnace. The Reverberatory Furnace is an instrument used in metallurgy for the isolation of metal by smelting the ore. The ore which contains the metal is melted by the generation of hot gases at the roof of the furnace. The metal does not come in contact with the fuel which is being used to heat it.

At smelting temperatures of the order of 1973–2073 K, these alloys are extremely fluid and it is important to ensure a “liquid tight” bottom. Furnaces used for the smelting of high-silicon alloys, i.e., over 70% Si, are mostly of the open-top type, and the carbon monoxide generated is burnt on the top of the furnace.
