In zone refining the impure metal rod is electrically heated till the metal in the heated zone melts. Pure metal is collected at one end of the rod. Repeating the metal with the product obtained each time highly pure metal is obtained. This method is very useful for producing semiconductor and other metals with high purity. For example- Germanium, Silicon, Boron, Gallium and Indium.
