  • Description:
    The Bureau of Mines has devised a procedure for recovering about 90 pct of the chromium and molybdenum and well over 90 pct of the nickel and iron from stainless steelmaking furnace dusts, swarf, and mill scale. Other metals such as manganese are also recovered. Initial laboratory results were confirmed and expanded to include a wide variation of stainless steelmaking waste mixtures. Later experiments included specialty steelmaking dusts other than from stainless steel. Significantly, the ease of technology transfer has been demonstrated by a number of industrial-sized (19-ton) commercial electric-furnace heats, in which the pelletized wastes represented some 10 to 20 pct of the furnace charge, replacing part of the normal scrap charge. Results of these successful large-scale trials are given. Cost evaluation indicates the procedure is economically attractive for stainless and other specialty steelmaking wastes.
