Dry Iron Ore Beneficiation Iron Ore Separation ST
Iron ore extraction is mainly performed through open pit mining operations, resulting in significant tailings generation. The iron ore production system usually involves three stages: mining, processing and pelletizing activities. Of these, processing ensures that an adequate iron grade and chemistry is achieved prior to the pelletizing stage.

US3672579A Process for beneficiating magnetite iron ore
A process for upgrading lowgrade magnetitecontaining iron ore with minimum fine grinding. The dry ore is first comminuted to between about threefourths 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.
