Sinter plant - ArcelorMittal in Belgium

Sinter plant. The most important raw material needed to produce steel is iron ore. But, as is the case with coal, iron ore cannot be used directly in the blast furnace. That is why we first have to create sinter. How does this work? In our sinter plants (Ghent), we bake a mixture of fine iron ores, ferruferous recuperation materials and fluxes.

Blast Furnace operation: HOW A BLAST FURNACE WORKS

Aug 04, 2011  Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from 0.5 to 1.5 inches. This ore is either Hematite (Fe 2 O 3 ) or Magnetite (Fe 3 O 4 ) and the iron content ranges from 50% to 70%.

FACT SHEET Energy use in the steel industry

The BF-BOF route produces steel using raw materials such as iron ore, coal, limestone and steel scrap. About 75% of steel is produced using the BF-BOF route. First, iron ores are reduced to iron, also called hot metal or pig iron. Then the iron is converted to steel in the BOF. After casting and rolling and/or coating, the steel is delivered as ...

Iron ore - Wikipedia

Iron ore being unloaded at docks in Toledo, Ohio. 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, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe ...

Bog iron - Wikipedia

Iron-bearing groundwater typically emerges as a spring.The iron is oxidized to ferric hydroxide upon encountering the oxidizing environment of the surface. Bog ore often combines goethite, magnetite, and vugs or stained quartz.Oxidation may occur through enzyme catalysis by iron bacteria.It is not clear whether the magnetite precipitates upon first contact with oxygen, then oxidizes to ferric ...

12.5 Iron And Steel Production

12.5.1.2 Iron Production - Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel. Iron
