    Unusually high cobalt contents of metavolcanics and of sulphide minerals in orebodies suggest a consanguinity between ores and rocks. 90% of total nickel, 70% of total cobalt but only 30% of total copper in rocks occur in silie phases and thus indie an early separation of copper from cobalt and nickel.

    Some metals are held inside rocks as minerals. The rock or mineral that holds the metal is called an ore. An ore is heated with chemicals until it melts and the pure metal separates out as a liquid. The liquid then cools and hardens. A few metals, such as gold, silver, and copper can be found in pure form as metal elements.
