  • Slag recyclingrecovery

    The terms blast furnace slag (BFS) and granulated blast furnace slag as well as LD slag and electric furnace slag are used for finer distinctions. With high-quality iron ore grades with an iron content of 64 to 67 a blast furnace typically produces about 0.25 to 0.30 t of slag per t of pig iron.

  • 86 IRON AND STEEL SLAGUSGS

     · Domestic Production and Use Iron and steel (ferrous) slags are formed by the combination of slagging agents and impurities during the production of crude (or pig) iron and crude steel. The slags are tapped separately from the metals cooled and processed and are primarily used in the construction industry. Data are unavailable on actual U.S. ferrous slag production but domestic slag sales1 in 2019 were estimated to be 17 million tons valued at about 470 million. Blast furnace slag was about 50 of the tonnage sold and accounted for 88 of the total value of slag most of which was granulated. Steel slag produced from basic oxygen and electric arc furnaces accounted for the remainder of sales. Slag was processed by 28 companies servicing active iron and steel facilities or reprocessing old slag piles at about 129 processing plants (including some iron and steel plants with more than one slag-processing facility) in 33 States including facilities that import and grind unground slag to sell as ground granulated blast furnace slag
