Abstract:
There are millions of tons of solid waste residues accumulated in present-day alumina industry. Those solid waste residues contain red mud and belit mud. The creation of sludge depository, its keeping and taking environmental protection measures cost up to $8-12 million a year. However, red mud is a valuable raw material. The extraction of some useful elements from red mud makes it possible to obtain such valuable products as pig iron, iron-bearing concentrate, rare-earth elements, alumina concrete, constructional materials, etc.
Keywords: red mud, pig iron, cement clinker, gelenite slag, phase composition, chemical composition
