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. Hence the feed for cassiterite flotation should be …

Cassiterite is a mineral composed of tin dioxide (SnO2) and is the primary ore of tin. It is generally brown or black in color and has a high density, making it easy to identify. The mineral can be identified by its hardness, which is 6 to 7 on the Mohs scale, and its luster, which is adamantine to submetallic.
