Extraction of Metals - Coggle Diagram

- - - - A new charge that is iron ore, coke and limestone are put into the top, and preheated air is blown into the bottom.
      - slag and iron are drained from the bottom of the furnace.
      - iron can be displaced by carbon - more efficient method than electrolysis
  - - - graphite anode and graphite cathode place in molten aluminium solution - solution: pure aluminium melted with molten cryolite
        
        molten liquid aluminium forms at the bottom of the electrolysis unit and is drained out
  - - - two rods of pure copper and impure copper are placed at the cathode and anode
        
        pure copper ions will move through the solution from the impure copper at the anode to the pure copper at t he cathode, and leaving the impurities behind as a pile of slag under the anode
