Tin processing
Tin smelting furnaces are one of three basic types: reverberatory furnaces, blast furnaces, or electric furnaces. Usually the operation is carried out as a batch process. 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 ...
Gold Ore Roasting Techniques
In such cases no practical amount of grinding or prolonged contacting of the raw ore with cyanide solution will affect more than a certain low extraction; in other cases, while the extractions may be acceptable, the consumption of cyanide is prohibitive, and roasting or, occasionally, pyritic smelting of the material is the only alternative.

Cassiterite
Cassiterite constitutes the chief ore of tin, as well as highly aesthetic and popular mineral specimen. Tin was a foundation of the beginning of metal smelting in the early Bronze Age and still constitutes one of the core materials of modern technology. Cassiterite is dense, resistant to abrasion, and stable in the surface Earth environment.

What is Smelting?
Cassiterite: 2SnO 2 + 2C = 2Sn + 2CO 2; Silver oxide: 2Ag 2 O + C = 4Ag + CO 2; Minium: 2PbO + C = 2Pb + CO 2; Smelting vs. Melting. Smelting should not be confused with melting, as melting at high temperatures without the use of a reducing agent will produce molten ore but will not melt the metal out of the ore.
