    How is Iron Made Into Steel? Sciencing

    Iron was the dominant metal for use in building and machinery until the modern era. Iron is still the main component of steel but when impurities are removed in the steel-making process, a stronger, lighter material results (steel). Steel is used in almost all modern buildings, automobiles, aircraft and appliances.

    How Is Steel Made? Wonderopolis

    By itself, iron ore usually has many impurities, such as silica, phosphorus, and sulfur. These impurities weaken iron. The process of making steel involves removing the impurities from iron and adding carbon to give steel its incredible strength. Metal can be extracted from ore by heating it to extremely high temperatures until it melts. This process is known as smelting.

    How Is Iron Extracted From the Earth? Reference

    Magnetite and hematite are iron oxides; however, the extraction of iron from an iron oxide involves a series of steps that begins when mined iron ore is crushed into smaller pieces by a crusher and then washed. The second step in the process is calcination or roasting of the ore, which removes certain impurities, carbon dioxide and other substances.
