The Practice Of Cassiterite Flotation In Bolivia

2016-9-28  The dressing of Bolivian tin ores has been done up to the present by classical gravity methods, taking advantage of the high specific gravity of cassiterite canpared with that of the accaupanying gangue. For this purpose, jigs and shaking tables are used in the treatment of the various size fractions in which the ore is classified.

A low-grade cassiterite-magnetite ore from Sichuan province, China, is finely disseminated, assaying 0.39% Sn and 23.20% Fe, respectively. Mineralogy studies show that the fine-sized cassiterite is mainly disseminated in iron minerals and gangue. Moreover, the embedded size of cassiterite is very fine and must be ground to −0.01 mm to achieve a degree of liberation of about 90%.
