Earth's crust contains more than 4 % of calcium carbonate.
Producing sponge iron and then working it was the earliest method used to obtain iron in the Middle East, Egypt, and Europe, where it remained in use until at least the 16th century.There is some evidence that the bloomery method was also used in China, but China had developed blast furnaces to obtain pig iron by 500 BCE.. The advantage of the bloomery technique is that iron can be obtained at ...

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H ...
The sponge iron production increased by 20% on a Y-O-Y basis in 2014 as the non-coking coal supplies improved. However, the sponge iron prices increased marginally by ~2% Y-O-Y owing to demand-supply mismatch. The EAF steel production grew 8% in the period as compared to a double digit growth in the production of sponge iron.

Iron ore. Iron ore is one of the basic among other raw materials used in the production of iron. It is described as any mineral substance that contains enough iron which makes its smelting a viable proposition, i.e an iron content if less than 20%. Ores vary considerably in form and composition from one source to another.
Jul 07, 2017· Limestone is also a very important industrial mineral. Its chemical properties make it a valuable mineral for a wide range of industrial/manufacturing uses. Limestone is also one of the vital raw materials used in production of iron and steel. Limestone, by definition, is a rock that contains at least 50 % of CaCO3 in the form of calcite by weight.
Limestone is the reducing agent, without limestone the iron ore Fe2O3 will never get reduced to Pig iron Fe .. calcination should be lesser inside the blast furnace to reduce the coke rate thats why sinter is being used nowadays, as in sintering process limestone is calcinised outside the furnace which reduces the coke rate by 58%.

Lime is used to convert iron into 'pig iron'. In the blast furnace, finely ground or granular limestone (with a low sulfur and alkali content) is used together with finely ground lime to convert ore into pig iron. The pig iron is later processed into steel. Lime is used as a fluxing agent in electric arc furnaces and basic oxygen furnaces.
The total capacity is reported to be about 11MT of sponge iron; in Chhattisgarh 4.5 MT, followed by 2.2 MT in Odisha and 1.6 MT in West Bengal. In India, most of the sponge iron producers do not have captive mines of any of the raw materials like hematite, non-coking coal and limestone, which are used for sponge iron production.
