IOP Conference Series: Earth and Environmental Science, 2019 Abstract Red mud - a bauxite residue, is a by-product of the Bayer Process for refining bauxite to alumina. Red mud is highly alkaline, due to the sodium hydroxide utilization to purify bauxite from silicate and other impurities. In order to produce one ton of aluminium, it will be yielded 0.8 to 1.5 tons of red mud is produced as by ...
