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.

iron ore market Mineralogy: hematite vs magnetite Iron ores can be formed of several different minerals; the most common are hematite and magnetite. DSOs, including the midgrade products Rio Tinto and BHP produce from Australia's Pilbara region and the highgrade 65% Fe fines Vale produces in Brazil, are predominantly hematite products.

Magnetite. Karara comprises a largescale, longlife magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (3436% Fe) than hematite ore (5864% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to produce a highgrade (+65% Fe) concentrate for steelmaking.

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, % Fe), hematite (Fe 2 O 3, % Fe), goethite (FeO(OH), % Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...
