Steelmaking Wikipedia

Primary steelmaking involves converting liquid iron from a blast furnace and steel scrap into steel via basic oxygen steelmaking, or melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking involves refining of the crude steel before casting and the various operations are normally carried out in ladles.

Iron Steel Business Recycling

Steel recycling generates a small water impact. This impact is due to steel production from sources generating blast furnace slag which in turn is used in concrete production as a substitute for cement. When recycling is undertaken, this process no longer occurs, so concrete production must revert to cement in place of blast furnace slag.

Smelting of lowgrade copper scrap begins with melting in either a blast or a rotary furnace, resulting in slag and impure copper. If a blast furnace is used, this copper is charged to a converter, where the purity is increased to about 80 to 90 percent, and then to a reverberatory furnace, where copper of about 99 percent purity is achieved.
