The invention relates to ferrous metallurgy. A method for production of aluminium ferrosilicon includes preparation of oxidation-reduction charge, which contains, wt. %: fine fraction waste coal – 30-75, ash of steaming coal firing – 10-30, wastes of coke and by-product process – 15- raw material is mixed with milling, controlling the set averaged value of the chemical composition of the basic oxides of the final charge, and then it is granulated. The invention allows to produce the standard grades of aluminium ferrosilicon on the basis of production wastes. |
