· Africa has the second largest ultimately recoverable resources (URR) of gigaton (Gt) iron (Fe) ore in the world. South Africa is among the countries in the world with high-quality iron ore deposits. The most significant sources of Fe ore in the African continent are hosted by the banded iron ore formation of Precambrian age with high …

· Composition: Iron ore is primarily composed of iron, usually in the form of iron oxides such as hematite (Fe2O3), magnetite (Fe3O4), or goethite (FeO (OH)). It may also contain other elements or minerals as impurities, such as silica, alumina, phosphorus, sulfur, and trace elements. Physical properties: Iron ore is usually hard, dense, and …

Current magnetite production is a by-product of the copper operations and as such is recovered from the Concentrator floatation tails stream by magnetic separation. Approximately 15%, by weight, of magnetite is removed by 'cleaning' and 're-cleaning' of the magnetic concentrate from the first stage.

· Iron ore tailings are industrial solid wastes generated from mineral processing. The disposal of iron ore tailings leads to environmental threat and serious security because of their tiny particle size and large storage. In this paper, suspension magnetization roasting and magnetic separation technology were utilized to recover …

· Hence, the low-grade iron ore needs to be beneficiated to make the iron ore concentrate suitable for iron-making process. Thus, the main objective of processing/beneficiation is Fe enrichment, thereby reducing gangue content, especially alumina, which occurs in iron ore deposits across many conuntries like India.
