The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (Foe (OH)), limonite (Foe (OH).n (H2O)) or siderite (FeCO3).

Crushing Processing Flow

Mostly iron ore is used for making steel. So we need the extraction of a pure metal from its ore. The extract the metal from ores, several physical and chemical methods are used. The method used depending upon chemical properties and nature of the ore from:
1. Crushing and grinding of the ore.
