The smelting and refining process for iron and steel in the BF-BOF process involves the carbon reduction of iron ore (Fe 2 O 3) in the BF to make molten iron, and decarburization of molten iron in the BOF to make molten steel. Major reducing agent in the BF is the carbon monoxide gas (CO) generated by the oxidation of the carbon (C) in coke.

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.

Although iron does not occur in its pure form in nature, some kinds of ore contain up to 70% iron atoms. 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.

The first metallurgical step involved in this process is to reduce iron ore to metallic iron in a blast furnace, using coke as both a fuel and reducing agent. The produced metallic iron contains a relatively high proportion of carbon (4%) and it is passed to the steelmaking process in the form of liquid at approximately 1450 C, called as ''hot metal''.
