ppt to manufacturing process of pig iron using iron ore Solutions Just Right For You

Iron processing Iron making Britannica The scarcity of coking coals for blastfurnace use and the high cost of coke ovens are two reasons for the emergence of this other alternative ironmaking process Smelting reduction employs two units in the first iron ore is heated and reduced by gases exiting from the second unit which is a smeltergasifier supplied with coal and oxygen Chemistry Notes for class 12 Chapter 6 General Principles and Processes of Isolation of Elements Earth crust is the source of many elements Out of these elements 70% are metals Aluminium is the most abundant metal of earth crust and iron comes second

CBSE Class 12 Chemistry Notes

Cast iron is different from pig iron and is made by melting pig iron with scrap iron and coke using hot air blast It has slightly lower carbon content (about 3%) and is extremely hard and brittle Wrought iron or malleable iron is the purest form of commercial iron and is prepared from cast iron by oxidising impurities in a reverberatory furnace lined with haematite

Is the product of the first step in turning Iron Ore to usable engineering steel is the production of pig iron A Charge A combination of Iron Ore Limestone and Coke (solid product of the destructive distillation of coal) that is loaded into the top of a blast furnace

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 the size of a marble (between 1/4 and 1/2)

Economics and Environmental Effects of the Steel Industry Other countries with substantial production of steel include in 2015 included Russia which produced 71 11 million metric tons in the same year followed by South Korea (69 73 million metric tons) Germany (42 68 million metric tons) Brazil (33 25 million metric tons) Turkey (31 52 million metric tons) and the Ukraine (22 93 million

12 06 2020Iron 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 silvery white appearance and distinctive magnetic properties It constitutes 5 percent by weight of the Earth's crust and it is the

The Bessemer Process was invented and patented in 1855 by Henry Bessemer This was the first inexpensive industrial process to make steel from molten pig iron Although the process had been used outside Europe for hundreds of years before this this was the first time it was used on an industrial scale

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 Pig iron has only limited uses and most of this iron goes on to a steel mill where it is converted into various steel alloys by further reducing the carbon content and adding other elements such as manganese and nickel to give the steel

charcoal flux and iron ore Molten iron was poured through a series of lateral sand troughs which resembled piglets suckling giving it the name pig iron By the late 1700's pig iron was being refined in puddling furnaces which allowed for excess carbon to be oxidized out of the mix As the carbon
