Mining waste generated from aluminium production

The production of aluminium involves three main stages: mining bauxite ore, refining bauxite to alumina (Al2O3), and then smelting alumina to produce aluminium. Bauxite comes from open mines mainly located in tropical and subtropical regions. On average it takes 4 to 5 tonnes of bauxite to produce 2 tonnes of alumina, yielding 1 tonne of aluminium. The main solid by-product of the alumina Get price
