Abstract

The present invention provides the method of producing a semi-product for manufacturing ferro- and master alloys and relates to metallurgy, specifically to the production of a metal-containing semi-finished product from wastes. Fine and dustlike oxidized metal-containing waste materials are agglomerated and for reducing the agglomerates are blended with metallic iron- or manganese-base melt with a higher content of silicon and carbon. Then the blend is held until complete separation of the metallic melt and the partially reduced semi-finished product. The technical result lies in broadening the types of the range of the wastes types that can be efficiently recycled.
