Magnetic properties in red mud after thermal treatment

p.1085-1088

Red mud is the waste of the Bayer technique, concerning the production of alumina out of bauxite ores. Red mud is an industrial waste and therefore the development of possibly useful products is always an interesting task in waste management. In this report, a pyro-metallurgical process is presented according to which the red mud may be transformed into magnetic powder, with relatively acceptable characteristics.
