Here the ore is put into a blast furnace along with limestone and coke and subjected to hot air blasting and heat which converts the ore to molten iron This is tapped from the bottom of the furnace into molds known as pigs and allowed to solidify into pig iron This pig iron is converted to wrought iron or processed into steel by several methods

Iron ore Wikipedia

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 limonite FeO OH ·n H 2 O 55% Fe or siderite FeCO

Pig Iron Manufacturing Process Metallurgist & Mineral Processing Engineer

Just as pig iron can be produced from iron ore in the electric furnace so can pig steel be produced by a close regulation of the carbon content of the charge Sufficient carbon is provided for reduction of the ore but not enough to combine to any appreciable extent with the product

Iron processing Definition History Steps Uses & Facts

Direct reduction in which iron ores are reduced at temperatures below the metal s melting point had its origin in such experiments as the Wiberg Soderfors process introduced in Sweden in 1952 and the HyL process introduced in Mexico in 1957 Few of these techniques survived and those that did were extensively modified

How to Manufacture Pig Iron How Pig Iron is made

3 Sponge Iron Process As the name implies the spongy iron is obtained by the reduction of lumpy iron ore or iron ore pellets from the oxide form into the metallic state The iron content of the product so obtained varies from 90% to 94% and the balance represents the traces of gangue and residual iron oxide

process flow iron production from its ore

Labrador Iron Mines Holdings Limited Iron Ore Products amp Markets During this process the iron ore is heated to extreme temperatures in blast furnaces where Since 1999 nearly all of Canada 39 s iron ore production has come from the Labrador Trough region in Labrador and Quebec facilitating export of its product to the leading importers of Canadian iron ore Processing Flow Sheet nbsp

The Step by Step Process of Producing Iron from Iron Ore

Now this carbon monoxide that is unstable reacts with the ore to form carbon dioxide and iron The Separation Of Iron The molten iron that settles down at the bottom of the furnace contains impurities and rocks that combine with the limestone to create slag This slag being lighter floats above the iron and is separated easily

How aluminium is produced

The next stage in the production chain is the processing of bauxite into alumina or aluminium oxide Al 2 O 3 a white powder The most common process for making alumina from bauxite is the Bayer process which was first discovered over 100 years ago but is still in wide use today About 90% of alumina refineries in the world use the Bayer
