1. Introduction. Iron-containing ore beneficiation includes several stages. For example: crushing to −30 mm size class and rough magnetic separation, further crushing of the recovered magnetic product to −10 mm size class and final magnetic metal content upgrading. All operations use dry methods.

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 ...
