Creating Iron | HowStuffWorks
Once it cools, this metal is known as pig iron. To create a ton of pig iron, you start with 2 tons (1.8 metric tons) of ore, 1 ton of coke (0.9 metric tons) and a half ton (0.45 metric tons) of limestone. The fire consumes 5 tons (4.5 metric tons) of air.
Iron Ore Smelting Process - Brighthub Engineering
Introduction to Iron Ore and Steel Smelting Processing. Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed, washed, and transported to the smelter. 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.
Limestone Is Used Purifying Iron Ore In Usa

Limestone and dolomite flux and their use in iron and ...
May 08, 2013 · Basically limestone is used as a slag former. Dolomite is used as a slag former, slag modifier and as a refractory material. The process of iron making is the reduction of iron ore to produce iron. Iron ore normally contain gangue materials such as silica (SiO2), Alumina (Al2O3) along with sulphur (S) and Phosphorus (P).
What is the use of limestone of in the extraction of iron ...
Jan 08, 2017 · Limestone is used in iron extraction to remove impurities from the iron and becomes molten slag. The calcium carbonate (CaO3) in limestone catabolically reacts, forming calcium oxide(CaO) and carbon dioxide(CO2). CaO is highly reactive when subjected to the extreme heat of the furnace. CaO can react with impure iron, such as iron sulfide(FeS).
Ironstone - Wikipedia
Ironstone, although widespread, is a limited source of iron (Fe). Historically, most of British iron originated from ironstone, but it is now rarely used for this purpose because it is far too limited in quantity to be an economic source of iron ore. Ironstones oxide impurities render it useless as a component in ceramics: the "ironstone china" of Staffordshire and American manufacture, a fine white high-fired vitreous semi-porcelain, commonly use…
iron ore in limestone - echtscheidingen-amsterdam.nl
The Birmingham District is a geological area in the vicinity of Birmingham, Alabama where the raw materials for making steel, limestone, iron ore, and coal are found together in abundance. The district includes Red Mountain, Jones Valley, and the Warrior and Cahaba coal fields in Central Alabama.
Iron Ore Mining Techniques, Metal Extraction, Types of ...
The iron ore, coke and limestone are crushed into small round pieces and mixed and put on a hopper which controls the input. The most common ores of iron are hematite Fe 2 O 3, and magnetite, Fe 3 O 4. These ores can extract iron by heating them with the carbon present in the coke. Heating coal in the absence of air produces coke.
Iron ore - Wikipedia
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. In 2011 the Financial Times has speculated that iron ore is "more integral to the global economy than any other commodity, except perhaps oil ".
Iron-Oxide Concretions and Nodules, 1 | Some Meteorite ...
Hematite and magnetite are two iron oxide minerals. Most iron ore deposits consist mainly of hematite, magnetite, or both. Iron oxide concretions, iron oxide nodules, and ironstones are often mistaken for meteorites because their unusual shapes catch people’s attention and they are denser than most other rocks. Hematite concretions form by precipitation of iron oxide from iron rich solutions.
Blast furnace - Wikipedia
Coke, limestone flux, and iron ore (iron oxide) are charged into the top of the furnace in a precise filling order which helps control gas flow and the stone reactions inside the furnace. Four "uptakes" allow the hot, dirty gas high in carbon monoxide content to exit the furnace throat, while "bleeder valves" protect the top of the furnace from sudden gas pressure surges.

Iron mining in the United States - Wikipedia
In the late 1700s the iron furnaces moved away from the bog iron ore of the coastal swamps, to larger iron ore deposits further inland. Inland locations also allowed the furnaces to be closer to sources of limestone, which was used as a flux in iron smelting.
SAIL ramps up iron ore production in 2019-20 - The ...
4 days ago · Selling of iron ore fines from SAIL mines has also been initiated to augment the countrys steel production, as the iron ore demand in the market is soaring. RMDs limestone production and despatch shot up to 1.24 mt and 1.25 mt respectively in FY20.
The Extraction of Iron - Chemistry LibreTexts
The function of the limestone. Iron ore is not pure iron oxide - it also contains an assortment of rocky material that would not melt at the temperature of the furnace, and would eventually clog it up. The limestone is added to convert this into slag which melts and runs to the bottom.
