Metal Ore

For most metals the process of changing from the ore form to the metal form is to use heat to drive off the oxygen and other components that have combined with the metal ore. Processing of the metal ore forces the electrons from other ions (oxygen, etc.) that are being removed by the process to attach to the outer shell of the metal ion to form ...
