Iron ore is an important raw material for iron and steel production enterprises After crushing grinding magnetic separation gravity concentration etc gradually we can get iron from natural minerals iron ore It is the mineral aggregates that contain iron or iron compounds which can be used economically Production Process of Iron Ore

The advantage of steel over iron is greatly improved strength The open hearth furnace is one way to create steel from pig iron The pig iron limestone and iron ore go into an open hearth furnace It is heated to about 1 600 degrees F 871 degrees C The limestone and ore

The 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

 · The Modern Steel Production Process Ironmaking the first step in making steel involves the raw inputs of iron ore coke and lime being melted in a blast furnace The resulting molten iron also referred to as hot metal still contains 4

Steel is simply low carbon iron As such the steel manufacturing process begins by smelting iron ore Fe 2 O 3 or Fe 3 O 4 in a blast furnace This smelting process melts out and separates iron from the original rock material Iron ore is mixed with coke a form of very pure coal

Iron ore is converted into various types of iron through several processes The most common process is the use of a blast furnace to produce pig iron which is about 92 94 iron and 3 5 carbon with smaller amounts of other elements

Iron was the dominant metal for use in building and machinery until the modern era Iron is still the main component of steel but when impurities are removed in the steel making process a stronger lighter material results steel Steel is used in almost all modern

 · The steelmaking process starts with the processing of raw iron ore The rocks that are mined containing iron ore are ground and the near elemental iron is extracted using magnetic rollers This fine iron ore is then processed into clumps that can be put inside of a blast furnace At the same time coal is cleaned of impurities in a furnace

requirements of steel customers in the blast furnace process The iron ore concentrate is now mixed and ready for the pelletizing process Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets in much the same manner that one rolls a snowball to make a pellet about

Instead the iron heats up into a spongy mass containing iron and silicates from the ore Heating and hammering this mass called the bloom forces impurities out and mixes the glassy silicates into the iron metal to create wrought iron Wrought iron is hardy and

 · Turning low grade iron ore into the most used metal in the world is no easy task Learn how this hot process works on Discovery Channel s HowStuffWorks show

 · Processing The first stage of turning iron ore into steel is the processing The rock is first grounded up with the ore being extracted using magnetic rollers The fine grained ore is then processed into coarse grained clumps which is

What We Do How we make steel How we make steel iron ore coke and limestone fines – are carefully stacked and blended then passed under an ignition hood at the sinter plant This heating process is carefully controlled to make sure the resulting sinter has the right composition and optimum sizes for the next stage of the process at

Blast furnace a vertical shaft furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore coke and flux fed into the top Blast furnaces are used to produce pig iron from iron ore

The charge of blast furnace possesses successive layers of iron ore scrap coke and limestone and some steel scrap which is fed from the top of the furnace Iron ore exists as an aggregate of iron bearing minerals These mineral aggregates are oxides of iron called hematite limonite and magnetite They all contribute to the smelting process

Iron processing use of a smelting process to turn the ore into a form from which products can be fashioned Included in this article also is a discussion of the mining of iron and of its preparation for smelting Iron Fe is a relatively dense metal with a

 · Cast iron begins its life as pig iron which is remelted and often combined with large amounts of scrap iron and sometimes with steel Contaminants are removed from the melted pig iron and the iron once melted is then cast Casting is the process of pouring the iron into

In HIsarna ironmaking process iron ore is processed almost directly into liquid iron or hot metal The process is based around a type of blast furnace called a cyclone converter furnace which makes it possible to skip the process of manufacturing pig iron pellets that is necessary for the basic oxygen steelmaking process

 · Open hearth process also called the regenerative open hearth A bit like a giant fireplace in which pig iron scrap steel and iron ore are burned with limestone until they fuse together More pig iron is added the unwanted carbon combines with oxygen the impurities are removed as slag and the iron turns to molten steel

 · The iron is periodically drained into a mold from a port at the bottom of the blast furnace where it cools The pig iron can then be converted into wrought iron by mixing it with silicon or processed further to create steel Steel is a form of iron mixed

The advantage of steel over iron is greatly improved strength The open hearth furnace is one way to create steel from pig iron The pig iron limestone and iron ore go into an open hearth furnace It is heated to about 1 600 degrees F 871 degrees C The limestone and ore

This pig iron is converted to wrought iron or processed into steel by several methods This is the first article in a series on metallurgy where we will examine the processing of iron ore into different grades of steel We start with the mining and preparation of the iron ore and shipping it to the smelter The Mining of Iron Ore
