Detailed explanation-1: -Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.
Detailed explanation-2: -Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route.
Detailed explanation-3: -Steel is made from iron by removing impurities and adding substances such as manganese, chromium, nickel, tungsten, molybdenum, and vanadium to produce alloys with properties that make the material suitable for specific uses.
Detailed explanation-4: -Types of Ore: Two major varieties used for iron making are Haematite Ore( Containing Ferric Oxide-Fe2O3) and Magnetite Ore (containing Ferro-Ferric Oxide-Fe3O4).
