Metals and their uses

Extracting Metals

  • Metals are usually found in the Earth's crust. They are often combined chemically with other elements such as oxygen.
  • An ore contains enough metal to make it worth extracting the metal.
  • The method we use to extract a metal depends on its reactivity.
  • Unreactive metals are found in the Earth as the metal.
  • The oxide of metals less reactive than carbon can be reduced using carbon.

Iron and steels

  • Iron oxide is reduced in a blast furnace to make iron.
  • Iron from the blast furnace is too brittle for many uses.
  • Most iron is converted into alloys called steels.
  • Steels contain carefully controlled quantities of carbon and
