Aluminum starts out as bauxite ore – an aluminum ore formed from laterite soil. Bauxite is the world's primary source of aluminum. Before it can become aluminum, however, bauxite destined for use as aluminum must first be processed into alumina.

Titanium oxide is a major component of bauxite residue (BR) with a high value, but it is often an unwanted element in common BR reuse options such as cement or iron production. Conventional carbothermic reduction smelting of BR produces a slag still containing a large amount of Ti. This study investigates an aluminothermic process for producing an FeTi alloy …
