Cassiterite is a tin oxide mineral, SnO₂. It is generally opaque, but it is translucent in thin crystals. Its luster and multiple crystal faces produce a desirable gem. Cassiterite was the chief tin ore throughout ancient history and remains the most important source of tin today.Cassiterite is a mineral composed of tin oxide (SnO2) and is the primary ore of tin. It has a high density and a hardness of 6 to 7 on the Mohs scale, making it relatively resistant to weathering and erosion. ...

Magnetic and non-magnetic cassiterite from St. Michael's Mount and Cligga Head, Cornwall, have been analysed by electron microprobe. Differences in their chemical composition are attributed mainly to the presence of inclusions of wolframite.

Large cassiterite crystals from the Pelepah Kanan tin mine in central Johore differ from those at Aberfoyle and Renison Bell, Tasmania, in showing strong colour zoning and possessing a small but conspicuous magnetic fraction. By separating crystals from these localities into fractions of varying magnetic susceptibility, there is found to be a distinct relationship between colouration and the ...Regarding the non-magnetic cassiterite concentrate, the best grades and recoveries of SnO 2 were obtained in #6 and #8 tests, for the 150/90 and <90 µm fractions, respectively, reaching grades of 78.23% and 77.34% SnO 2 and recoveries of 94.39% and 95.57% SnO 2, respectively .Characterization, Classification, Dry High-Intensity Magnetic ...Looking for Cassiterite?
