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 ...

The iron (Fe) content of such ores ranges from 72% to 35%. The highly friable and fully liberated constituents in ore, such as alumina and silica, generate a large quantity of fines during mechanized mining and crushing. Fine gangue material or iron ore slimes having <45%–55% Fe are discarded as reject during the ore beneficiation process.
