Definition of CASSITERITE. : a brown or black mineral that consists of tin dioxide and is the chief source of metallic tin âcalled also tinstone.
Cassiterite is reduced to tin by heating with carbon at 1200Â°C to 1300Â°C. Reverberatory furnaces are used to smelt tin concentrate and, for additional tin recovery, to re-smelt slag, which is left after the ore has been smelted. A furnace charge consists of cassiterite, a carbon-reducing agent, and limestone and silica fluxes. Smelting takes 10 to 12 hours.
