Upgrading Diasporic Bauxite Ores for Iron and Alumina

A technical route has been proposed to upgrade diasporic bauxite ores for iron and alumina enrichment based on reductive roasting, followed by magnetic separation and alkaline leaching. The thermodynamic analysis revealed that by reductive roasting of the bauxite ore at 9801100°C, hematite in the ore is transformed to magnetite and kaolinite
