#### Extraction of Iron Metallurgy Blast Furnace

At 900 1500 K, In the lower sections of the furnace, $C + CO_ {2} \rightarrow 2 CO$ $3FeO + CO_ {2} \rightarrow Fe + CO_ {2}$ The limestone also decomposes to CaO which removes the silicate impurity of the ore in the form of Slag. It can be easily separated out of molten iron.

#### Extraction of Iron from its ores, Iron dressing,

23/10/2018· Iron ( 26 Fe: (18 Ar), 4S 2, 3d 6 ) is found in the earth’s crust in the form of natural ores which contains different iron oxides mixed with impurities such as Silica (SiO 2), (Al 2 O 3), CaO, and MgO, and some harmful impurities such as s, p and As, The suitability of the ore in the extraction of iron economically depends on three factors which are:

#### Mining of Iron Ores IspatGuru

14/03/2014· Open pit and open cut mining are the least expensive techniques for the ore extraction. Overburden and stripping ratios are important in determining whether a deposit is to be mined. The stripping ratio describes the unit of overburden that must be removed for each unit of crude ore mined. A typical open pit iron ore mine is shown in Fig 1

2c. NOTE on RECYCLING Iron and Steel. About 42% of iron/steel in goods/components manufactured in iron/steel is recycled iron/steel, whether it be steel pans, car bodies, bridge girders, stainless steel cutlery etc.; This makes good economics because recycling saves on several costs AND allows a mineral resource like iron's haematite or magnetite ore resources to last a lot longer slower

#### Iron removal by physical chemical way

Iron is one of the most abundant metals of the Earth's crust. It occurs naturally in water in soluble form as the ferrous iron (bivalent iron in dissolved form Fe 2+ or Fe(OH) +) or complexed form like the ferric iron (trivalent iron: Fe 3+ or precipitated as Fe(OH) 3).The occurrence of iron in water can also have an industrial origin ; mining, iron and steel industry, metals corrosion, etc.

#### Bessemer process Wikipedia

The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace.The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten.
