01/03/2000The thermal evolution of bauxite-derived red mud was studied in this work by different complementary techniques. Dried red mud is substantially inert up to 900C, the loss of H 2 O from aluminium hydroxides and of CO 2 from silico-alumino-carbonates being the only detectable effects. At 900C red mud is dark red in colour.
