Bauxite is one of the world s most abundant minerals and is strip-mined in many places. Nearly all is processed into alumina for aluminium production. Bauxite contains iron-bearing clay or red mud, which often leaves stains on the hold paint that can prove difficult to remove. Bauxite is an aluminium ore and is the main source of aluminium.

This work presents a semi-smelting reduction and magnetic separation process for the recovery of iron and alumina slag from iron rich bauxite ore. The effect of the process parameters on the recovery rate of iron, maximum particle size of the iron nugget, and the Al2O3 content of the alumina slag was investigated and optimized. The results show that the iron …

One of the major constituents in the bauxite residue is iron oxide as Fe 2 O 3 (35–55% depending on the bauxite characteristics) and can be recovered after employing suitable physical separation processes. Increase in iron oxide content in red mud will enhance its utilization in the extraction of iron metal.
