FIELD: metallurgy.
SUBSTANCE: invention refers to non-ferrous metallurgy, and namely to complex processing of red muds of alumina industry. Processing method of red muds of alumina industry involves obtaining of red mud pulp, extraction and concentration of rich components by combination of classification and magnetic separation methods. After the pulp classification, fine-grain fraction pulp is extracted and subject to vibrocavitation treatment and further magnetic separation with extraction of magnetic and non-magnetic products. At that, magnetic product is subject to additional classification so that iron-bearing and scandium-bearing concentrates are obtained.
EFFECT: increasing the complexity degree of processing of red muds owing to increasing the extraction degree of rich components to target products - scandium-bearing concentrate and iron oxide concentrate.
