The process of zone refining is to be described. Concept introduction: The naturally occurring chemical substances in the form of which metals occur in earth, along with impurities, are called minerals. A mineral from which a metal is economically and conveniently extracted is called an ore. An ore contains many impurities that are removed by purification. Minerals are the halides, oxides, carbonates, silicates, sulphides, and sulfates of metals. The impurities of metals are removed by purification processes. The process of purifying crude metals is called refining. The purification depends upon the nature of the metal and the nature of the impurities to be removed. Zone refining is a method to obtain metal with high purity. Zone refining is based upon the principle that impurities are more soluble in the molten state than in the solid state.
