Iron ore is the source of primary iron for the world s iron and steel industri It is therefore essential for the production of steel which in turn is essential to maintain a strong industrial base Almost all 98 iron ore is used in steelmaking Iron ore is mined in about 50 countriMar 16 32 Major DRI production processes are either gas based or coal based Feed material in a DRI process is either iron ore sized to 10 to 30mm or iron ore pellets produced in an iron ore pellet plant In the gas based plant the reactor the reduction reaction takes place is a shaft furnace

The primary use of iron ore is in the production of iron Most of the iron produced is then used to make steel Steel is used to make automobiles locomotives ships beams used in buildings furniture paper clips tools reinforcing rods for concrete bicycles and thousands of other items It is the most used metal by both tonnage and purposeIron Ore Smelting Process Brighthub Engineering Large scale iron ore smelting has been carried out in numerous types of blast furnaces since the industrial revolution with the basic ingredients of coke iron ore and limestone remaining unchanged being loaded into the blast furnace from where the molten iron is tapped into molds

This statistic shows the worldwide iron ore production by country The mine production of iron ore in the United States reached approximately 56 million metric tons in The ore is loaded into a blast furnace along with measured quantities of coke and limestone Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature The iron is reduced from the ore by carbon in the coke the limestone aiding slag separation from the molten iron The slag and molten iron are tapped off from the bottom of the furnace the slag being

For these reasons iron ore production is concentrated in the hands of a few major players World production averages two billion metric tons of raw ore annually The world s largest producer of iron ore is the Brazilian mining corporation Vale followed by Anglo Australian companies Rio Tinto Group and then BHP BillitonIron making Iron ore is mined in around 50 countries the largest producers are Australia Brazil and China Around 98 of iron ore is used in steel making During the iron making process a blast furnace is fed with the iron ore coke and small quantities of fluxes minerals such as limestone which are used to collect impurities

Pig iron Raw iron the immediate product of smelting iron ore with coke and limestone in a blast furnace Pig iron has a very high carbon content typically 4 5 which makes it very brittle and not very useful directly as a material A Selection of Mechanical Properties from Gordon Wrought iron 20 000 to 40 000 10 000 to 40 000 and 90 IRON ORE1 Data in million metric tons usable ore unless otherwise noted Domestic Production and Use In mines in Michigan and Minnesota shipped 98 of the usable iron ore products in the United—the remaining 2 of domestic iron ore was produced for nonsteel end uses—with an

Jul 26 32 Arguably the key development came in 4 when Henry Cort introduced the puddling and rolling techniqu These were ways of getting all the impurities out of iron and allowing large scale production and a vast increase in it The iron industry began to relocate to coal fields which usually had iron ore nearbyIron ore is found in nature in the form of rocks mixed with other elements By means of various industrial processes incorporating cutting edge technology iron ore is processed and then sold to steel compani The iron ore produced by Vale can be found in houses cars and applianc

Iron ore as mined is a combination of iron with oxygen and various other unwanted substances generally known as gangue The first metallurgical step is to reduce iron ore to metallic iron a process which is mostly carried out in a blast furnace using coke as both a fuel and reducing agentCoal is cleaned of impurities in a coke furnace yielding an almost pure form of carbon A mixture of iron ore and coal is then heated in a blast furnace to produce molten iron or pig iron from which steel is made ArcelorMittal has a diversified fleet of production facilities to make steel both basic oxygen furnaces and electric arc furnac

173 The more advanced way to smelt iron is in a blast furnace A blast furnace is charged with iron ore charcoal or coke coke is charcoal made from coal and limestone CaCO 3 173 Huge quantities of air blast in at the bottom of the furnace and the calcium in the limestone combines with the silicates to form slagThe direct production of steel from iron ore in the electric furnace has never passed beyond the laboratory stage 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
