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.

Dry Iron Ore Beneficiation | Iron Ore Separation
Dry processing of iron ore presents an opportunity to eliminate costs and wet tailings generation associated with flotation and wet magnetic separation circuits. STET has evaluated several iron ore tailings and run of mine ore samples at bench scale (prefeasibility scale). Significant movement of iron and silies was observed, with examples ...

Recovery of Iron Values From Tailing Dumps Adopting ...
The studies on hydrocyclone and magnetic separation had indied that an iron concentrate of 61 65 per cent Fe could be obtained by recovering 59 78 per cent of the iron values present in the slimes. Depending on the nature of the slimes the alumina and silica levels have been brought down to and per cent respectively.
