cassiterite (kəsĭt`ərīt), heavy, brown-to-black mineral, tin oxide, SnO2, crystallizing in the tetragonal system. It is found as short prismatic crystals and as irregular masses, usually in veins and replacement deposits associated with granites. Since it is hard, heavy, and resistant to weathering, it often concentrates in alluvial deposits derived from cassiterite-bearing rocks. It is the principal ore of tin and is mined in many countries; the most important sources are Malaysia, Thailand, China, Indonesia, Bolivia, and Russia. Except for Bolivia, nearly all of this production is from alluvial deposits. How to thank TFD for its existence?

A combination of well-characterized minerals and synthetic materials were used to calibrate for EPMA, including SMS scapolite (S and Cl), Corning W glass (6) (Co), SMS gahnite (Zn), SMS cassiterite (Sn), SMS strontianite and Corning X glass (Sr). They then culled quartz and limestone from Iron-rich magnetite and cassiterite, a tin oxide mineral, When ground liner, the purplish cassiterite breaks Into smaller particles than the Iron mineral, and can be separated out. Less common quartz mica rich pegmatite float mineralized with coarse cassiterite yielded up to 800 g/t Ta2O5 and 2. |
