The composition, recycling and utilisation of Bayer red mud

Bauxite residue, or red mud, is a solid waste produced from the alumina refining of bauxite ore. Red mud is mostly collected from the Bayer process which uses sodium hydroxide to dissolve the aluminium silicate. Typically, about 1 to 1.5 tonnes of red mud remains from the production of 1 t of alumina (Zhang et al., 2011).
