Iron Ore Slag Recycle

Blast Furnace Slag

Blast Furnace Slag

In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel. The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product. This molten iron product can be cast into iron products, but is most often used as a feedstock for steel production. Blast furnace slag is a ...

Recycle with High Performance

Blast furnace (BF) slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace. When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silies of the ore and coke ash to form a nonmetallic product called blast furnace slag. During the period of ...

 · With the existing technology (the bloomery process), it was necessary to use rich, highgrade iron ores, since during reduction, a great amount of iron is lost into the slag. This results in an extremely low yield; under usual reduction conditions (1100–1350°C), an ore with an irontosilica ratio lower than three may result in zero free iron, and therefore no yield at all [ 7 ].

Iron ore

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, % Fe), hematite (Fe 2 O 3, % Fe), goethite (FeO(OH), % Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...
