cassiterite | mineral | Britannica
cassiterite, also called tinstone, heavy, metallic, hard tin dioxide (SnO 2) that is the major ore of tin. It is colourless when pure, but brown or black when iron impurities are present. Commercially important quantities occur in placer deposits, but cassiterite also occurs in granite and pegmatites. Early in the 15th century, the cassiterite veins in Saxony and Bohemia were mined for tin ...

Cassiterite - Mineral Properties - Used as an Ore of Tin
Cassiterite is a tin oxide mineral with a chemical composition of SnO 2. It is the most important source of tin, and most of the world's supply of tin is obtained by mining cassiterite. Small amounts of primary cassiterite are found in igneous and metamorphic rocks throughout the world. It is also a residual mineral found in soils and sediments.

Cassiterite Flotation - Mineral Processing & Metallurgy
Cassiterite Flotation – Tin Oxide. The nominal size range for cassiterite flotation is between 2 and 100 microns. The top size is variable depending upon the liberation of the cassiterite particles. Cassiterite grains coarser than 100 microns are difficult to float whilst grains finer than 2 microns give selectivity problems.
