Ironmaking Process
In its Technology Roadmap Research Program, the American Iron and Steel Institute defined an ideal ironmaking process as one that eliminates the need for coal and coke ovens (and hence reduces the emissions of CO 2), that is able to use low-quality iron ores, that requires lower capital investment than the combination of coking oven and BF, and that is able to produce 5000–10,000 tonnes of

Iron Ore Smelting Process
Limestone is used as a flux to separate the gangue from the molten iron ore, the accumulated slag and the molten iron being tapped from two tap-holes at the bottom of the furnace. The slag goes to a disposal area and the molten iron is directed into molds known as pigs where it solidifies to pig iron and is transferred to the next stage of processing.

Iron Ore
Iron ore sintering and pelletizing are the predominant processes in the iron-making industry [1,2]. During the iron ore sintering process, calcium ferrite phase is believed to be the most desirable bonding phase because it has high reducibility and sufficient mechanical strength [3–5].

Iron ore pelletizing
Iron ore can be upgraded to a higher iron ore content through beneficiation This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which don’t need beneficiated, fines which are generated can be pelletized and used instead of being disposed of.

Processes and Procedures in the Extraction of Iron
The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.

How is Iron Refined from Ore? (with pictures)
Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires

Extraction of Iron- Know the Iron Extraction Process
The extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores. The common ores of iron are iron oxides. These oxides can be reduced to iron by heating them with carbon in the form of coke. Heating coal in the absence of air produces coke.

Pathways to decarbonisation episode two: steelmaking technology | BHP
In the DRI process, iron ore in the form of lump or pellets is reduced to metallic iron in the solid state unlike in the BF where the material is melted. Today, about 100 Mt of DRI is produced globally each year, with the majority of that using reformed natural gas (essentially splitting natural gas into hydrogen and carbon monoxide) to strip away the oxygen from the iron ore.

What is the use of limestone of in the extraction of iron from ores
Answer: Usually, limestone (calcium carbonate, CaCO3) is “calcined" in a lime kiln, where it is heated to form lime (CaO) and CO2 gas. The lime is then used in both steelmaking furnaces to refine liquid iron into steel, and also on ladles as slag to further refine the steel.

Steel Production
The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen.
