CHARGE FOR MANUFACTURING OF BRIQUETTS FOR METALLURGICAL MANUFACTURING ON BASIS OF INDUSTRIAL WASTES, CONTAINING OXIDATED IRON-BEARING MATERIAL Russian patent published in 2010 - IPC C22B7/00 C22B1/248 

FIELD: metallurgy.

SUBSTANCE: charge on the basis of industrial wastes, containing oxidised iron-bearing material, contains organic and/or mineral binder and water. In the capacity of oxidised iron-bearing material it contains extracted from iron-ore concentration wastes iron-ore concentrate, of fraction from 0.1 mm up to 10 mm. Ratio of components in charge is following, wt %: extracted from iron-ore concentration wastes iron-ore concentrate - 88-90%, binder - 10-12%. Additionally content of technical water subject to moisture in components is 8-10% of materials mass of charge.

EFFECT: return of iron-ore concentration wastes into metallurgical manufacturing in the form of raw material with increased content of iron oxides, provides receiving of significant saving of lump ore, pellets and in whole provides environmentally-friendly method of residue utilisation.
