Beneficiation of Iron Ores – IspatGuru

The process adopted to upgrade the Fe content of iron ore is known as iron ore beneficiation (IOB). However, Iron ores from different sources have their own peculiar mineralogical characteristics and require the specific beneficiation and metallurgical treatment to get the best product out of it.

US3672579A - Process for beneficiating magnetite iron ore ...

A process for upgrading low-grade magnetite-containing iron ore with minimum fine grinding. The dry ore is first comminuted to between about three-fourths inch and 10 mesh particle size and magnetically separated. The dry tailing is discarded and the concentrate is ground to between about 20 and 100 mesh and again subjected to dry magnetic separation.
