Mining Mining can be subdivided into 4 basic types: ... In order to extract a metal, the ore or compound of the metal must undergo a process called reduction to free the metal ( the positive metal ion gains negative electrons to form the neutral metal atom, or the oxide loses oxygen, to form the free metallic atoms). The chemical that removes the oxygen from an oxide is called the reducing ...

How Is Iron Extracted From the Earth?

How Is Iron Extracted From the Earth?

 · Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
