Detailed explanation-1: -There are three main raw materials needed to make steel. Iron ore, coal and scrap steel.

Detailed explanation-2: -The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks.

Detailed explanation-3: -Iron ore is the source of primary iron for the world’s iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries.

Detailed explanation-4: -The 1st area is the blast furnace area, where ironmaking of iron ore, coking coal, and other raw materials is carried out in an integrated manner. The 2nd area is the electric furnace area, where steelmaking and steel products are produced by melting iron and steel scraps and removing impurities.

Detailed explanation-5: -The main raw materials used in the iron and steel industry are iron ore, manganese, limestone, silica, chromate, feldspar, scrap iron flux and fuel.
