Raw Materials. The iron content of these ores ranges from 70% down to 20% or less. Coke is a substance made by heating coal until it becomes almost pure carbon. Sinter is made of lesser grade, finely divided iron ore which, is roasted with coke and lime to remove a large amount of the impurities in the ore.
Pig iron contains 4 to 5 percent carbon and is so hard and brittle that it''s almost useless. If you want to do anything with it, you have three options. First, you can melt it, mix it with slag and hammer it out to eliminate most of the carbon (down to 0.3 percent) and create strong, malleable wrought iron.

The molten metal withdrawn from the furnace is called "Pig Iron". It is either converted into wrought iron or steel or cast into moulds which or remelting and recooling produces cast iron. Wrought Iron: Wrought iron is comparatively pure form of iron it contains not more than 0.5 percent impurities of which carbon amounts to 0.2 percent.
In Bellary, open cast mining is being adopted. The iron ore variety (hematite) found in Bellary has higher concentration of iron (62 percent to 68 percent) which results in generation of comparatively lesser quantum of waste (25 percent of the ore mined).

Iron ore is mixed with coke, a form of very pure coal. The blast furnace burns the coke to heat the iron ore causing it to react into iron (Fe 2), nitrogen (N 2), and carbon dioxide (CO 2). This iron is often known as "pig iron" or "hot metal" as it is a liquid iron that flows from the bottom of the blast furnace.
