  • Zone Refining

    Zone refining refers to the method of purifying a crystal wherein a thin region of the crystal undergoes melting. This 'molten zone' is now moved across the crystal. The impurities in the metal are melted at the forward edge by the molten zone and move through the block of metal, leaving the solidified pure element behind.
