Abstract
In the low temperate sintering of bauxite with alkali, the magnetic properties of red mud change on account of the formation of a new mineral—maghemite. By this means, waste production may be reduced by a factor of 1.5. The concentrates obtained are suitable for use in ferrous and nonferrous metallurgy and in rare-earth production. This technology provides environmental benefits and expands the range of raw materials for steel production.
