Tin Ore Beneficiation Methods And Some Practice
The beneficiation method of tin ore is determined by its own characteristics. Because the density of cassiterite is higher than that of co-existing minerals, the traditional beneficiation process of tin ore is gravity beneficiation. With the passage of time, the granularity of cassiterite in the selected ore has been continuously reduced, so ...

22.4: Beneficiation
Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and flushed …
