    Oct 06, 2021 Bauxite is used to produce alumina, which is then used to produce aluminum. Wastes can be generated at several points in the production process, including during the mining of the bauxite ore, and during the refinery production process. The refinery processes used to produce aluminum generates about 2 – 2.5 tons of solid waste for every 1 ton

    The main constituent of bauxite residue is iron oxide and it can make up to 45% of the mass of the bauxite residue. In fact, the red colour of bauxite residue is caused by iron (III) oxides (mostly haematite, Fe 2 O 3) ( 9 ). In general, due to its high alkaline (Na 2 O ≈ 10%) and its titanium (TiO 2 ≈ 4–15%) content, bauxite residue is
