Description
Cassiterite is a tin oxide mineral, SnO 2 . It is generally opaque, but it is translucent in thin crystals. Its luster and multiple crystal faces produce a desirable gem. Cassiterite has been the chief tin ore throughout ancient history and remains the most important source of tin today.
Properties
Cassiterite crystalizes in the tetragonal crystal system with the chemical composition SnO2 and develops mostly short to long, prismatic, acicular or bipyramidal crystals, but also granular to massive aggregates with brown-black, grey, yellow-brown, green or red coloration. It is smelted at temperatures of around 1000 degrees Celsius.

Application
With a theoretical tin content of 78.8 percent, cassiterite is the only tin ore, with worldwide significance. The tin extracted from cassiterite is used as a non-toxic, rust-resistant coating for steel containers (tinplate), as well as for the production of various household items, cars and machinery.
