22.4: Beneficiation
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. The iron ore magnetite, Fe 3 O 4, is ferrimagnetic. It can be separated from abundant deposits of taconite by grinding to a ...
