Slag recycling - recovery
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. In the case of inferior grade ores below 60 %, the amount of slag is typically 0.35 to 0.50 slag/t of pig iron [1].Generation of iron and steel slag : NIPPON SLAG,During the process of reducing iron ore, it is necessary to remove the silica, alumina (Al 2 O 3), and other non-ferrous components contained in iron ore. The added limestone fuses with these components and lowers their melting point, making it easier to separate them from the iron and recover them. This recovered substance is slag.GENERAL INFORMATION Iron & Steel Slags about NSA IRON,,iron oxide in steel slag needed in the chemistry of Portland cement. Using 10 -15% steel slag will save a corresponding amount of CO 2 and provide the cement industry with real energy savings. Synergy of locations between the cement industry and the steel industryKR20160072848A - Method of recovering of Iron from slag,,Provided is a method to recover iron from a slag. The method to recover iron from the slag may comprise: a step of preparing slag containing iron oxide; and a step of injecting a reducing agent having a molar ratio of aluminum to iron oxide of 0.8 or more into the slag, and recovering iron from the slag.
