A process for enhanced removal of iron from bauxite ores ...

Abstract A process to remove iron from bauxite ore is described in which the ore is first finely crushed, calcined, and contacted with a reducing gas to convert iron present as very weakly magnetic goethite or hematite to magnetite or elemental iron. The ore is then passed through a magnetic separator to remove the iron. A 1.5% Fe2O3 product was produced from an Alabama bauxite ore analyzing 2 ...
