Dry beneficiation of iron ore - Mineral Processing

The most important iron ores are haematite (Fe 2 O 3) with up to 69.9 % iron content, magnetite (Fe 3 O 4) with up to 74.2 % and siderite (FeCO 3) with up to 48.2 % iron content. However, the ore deposits also contain impurities (gangue) like silicates or silicate-containing rock, and magnetite ore can rarely be extracted with an iron content higher
