What constitutes mineral beneficiation? Ore is an aggregate of minerals and contains valuable and gangue minerals. The mineral beneficiation involves separations of gangue minerals from ore and is done in the following two stages: 1) Liberation of valuable mineral by size reduction technologies. In most ores the valuable minerals is distributed ...

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 away.
