The Extraction Of Metals The extraction of metals from their ores is usually described as metallurgy, and metallurgical chemistry is a special branch of chemical science which is usually conducted on a large scale at high temperatures.

There are 3 main methods of extracting metals from their ore. They are reduction of the ore with carbon, reduction of the molten ore by electrolysis, and reduction of the ore with a more reactive metal. Extraction using carbon. Metals such as zinc, iron and copper are present in ores as their oxides. Each of these oxides is heated with carbon to obtain the metal.

EXTRACTION OF IRON. The process involves the crushing and washing of ore. Calcination or Roasting of ore: The concentrated ore is now heated in the presence of air. The process of roasting is performed to remove moisture, CO 2, impurities of sulphur, arsenic. Ferrous oxide is also oxidized to ferric oxide.
