What is the Beneficiation Process?-AZoMining.com
Oct 1 2014. The beneficiation process can be defined as a treatment process of ore which results in a more concentrated form of the product. It is often used in the preparation of iron ore for smelting. This is an essential process as it helps improve the yield from a deposit of ore, thereby increasing the potential profits that can be obtained

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 away.
