Cassiterite: The tin mineral cassiterite information and ...

Cassiterite is the best-known tin mineral. It has been used as the chief ore of tin from early history throughout the ages, and remains so even today. Some of the economical Cassiterite deposits exist in placer stream deposits where this very heavy mineral collects as rounded waterworn pebbles. The name Cassiterite is derived from the Greek "kassiteros", meaning tin.

Cassiterite - an overview | ScienceDirect Topics

Cassiterite is a friable mineral which readily produces slime size particles and therefore requires slime concentrators such as the Bartles–Mozley separator. Slimes separation however is less efficient than sand separation and the concentrate and middlings produced by a slimes table often require further treatment.

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. Hence the feed for cassiterite flotation should be reduced to 95% minus 100 microns and then deslimed ...
