Re‐using bauxite residues: benefits beyond (critical

2018-5-7  Bauxite residues (also known as ‘red mud’, ‘Bayer process tailings’ or ‘bauxite process tailings’) are generated from alumina production where bauxite is digested in hot NaOH solution via the Bayer process. 22 The production of 1 tonne of alumina generates between 1 and 1.5 tonnes of bauxite residue. 23 Currently, the yearly global production of bauxite residues is 150 million tonnes (Mt) 24
