Zusammenfassung:PCT No. PCT/NO94/00149 Sec. 371 Date Mar. 13, 1996 Sec. 102(e) Date Mar. 13, 1996 PCT Filed Sep. 9, 1996 PCT Pub. No. WO95/08005 PCT Pub. Date Mar. 23, 1995In the production of ferrosilicon in an electric reduction furnace by the reaction of iron-containing, silica-containing and carbonaceous materials, agglomerates containing a substantially homogeneous mixture of iron or a reducible iron compound and a carbonaceous material are used to replace at least a portion of the iron-containing materials in the furnace. These agglomerates have a weight ratio of carbon to iron of 0.2:1 to 1.5:1 in their reduced form after reaction in the furnace.
