Bayer process tailings

Ujaczki Éva

Bauxite residue is also known as red mud, Bayer process tailings or bauxite process tailings (Evans, 2015) and it may be split further into two fractions. The fine fraction, ‘red mud’ and the coarse fraction ‘process sand’ (>106μm or >150μm) (Courtney and Timpson, 2005).
