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.

There are three pieces of information one should have: 1) liberation size and top grain size of the cassiterite, 2) size by size analysis (SxS), and 3) green field or brown field context. Cassiterite is brittle and the design of the comminution circuit may limit what can be achieved by gravity separation which works best at the coarser sizes.
