The process of extracting iron ore begins with blasting, which involves using explosives to break up the ore-bearing rock into smaller pieces. This is followed by crushing and screening the ore in a crusher, and then transporting the ore to a concentrator for further processing. After that, the ore is separated by either flotation or magnetic separation techniques. Finally, it is filtered and then processed in a blast furnace to extract pure iron.

There are several ways to extract iron ore from rock. Here is a basic flow chart outlining the steps involved in the production of iron from iron ore:

  1. Mining: Iron ore is typically mined in large, open pits using heavy machinery.
  2. Crushing: The extracted iron ore is then crushed into fine powder to prepare it for the beneficiation process.
  3. Beneficiation: The beneficiation process involves separating the ore particles into a concentrate, which is typically about 65% iron, and waste material, known as tailings. This is typically done using magnetic separation or froth flotation.
  4. Smelting: The concentrate is then smelted to produce pig iron, which is about 92-94% iron and 3-5% carbon, with smaller amounts of other elements.
  5. Refining: The pig iron is then refined to produce steel, which is a more pure form of iron with fewer impurities. This is typically done through the Bessemer process or the open-hearth process.
