    Copper is the only naturally occurring metal other than gold that has a distinctive colour. Like gold and silver, copper is an excellent conductor of heat and electricity. It is also very malleable and ductile. Copper is also resistant to corrosion it does not rust very easily. Copper is soft but tough.

  • Extracting Metals By Electrolysis

    Extracting aluminium Aluminium is more reactive than carbon and its ore has a very high melting point 2050C. This means aluminium cannot be extracted by reduction with carbon. Electrolysis is used to extract aluminium from its ore. In electrolysis, the ore is dissolved in a compound called cryolite Na 3 AlF 6, which lowers the melting
