  • Iron Ore Magnetic Separation Calculations

Investigation of the effect of mineral composition and size on …

The economical minerals in the orebody are hematite (Fe 2 O 3) magnetite (Fe 3 O 4) and goethite (FeO·nH 2 O), although this last mineral is not well recovered by the actual concentration process. The main gangue mineral is quartz. Table 1 lists the minerals of the orebody. Iron, the valuable element, is carried by more than 3 recoverable minerals of different …
