Have been developed a scheme of enrichment (benification) of magnetite iron-ore concentrates with total content of Fet = 31 % in ore at magnetic separator and obtained a superconcentrate with Fet = 69,50 %. Experimentally determined that the reduction reaction degree of Fe by coal increases linearly with increasing of the content of Fe in concentrate. Certainly it has positive influence of decreasing the content of more difficult for reduction and poor magnetic iron containing components in the processing of wet magnetic separation (WMS). Almost all iron are in the form of good to reduce magnetite in the superconcentrates and enrichment of concentrate accompanying with growth of specific surface.
