Cassiterite An Overview Sciencedirect Topics

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. The quantity of coke and flux is carefully adjusted so as to produce an almost neutral slag ie, acid-to-base ratio is 1.

The end product is a cassiterite concentrate containing about 70 tin. Vein and disseminated tin deposits are mined by the same methods used in hard-rock mining of other non-ferrous ores such as zinc. The ore is broken by drilling and blasting, transported to a concentrator where it is crushed and ground and then concentrated by gravity methods
