@Rajni.
Zone refining is a method of purifying a crystalline solid, semiconductor or solid by causing a narrow molten zone to travel along a solid rod at which impurities become concentrated.

This method is based on the principle that the impurities are more soluble in the melt than in the solid state of the metal.

Zone refining or Fractional Crystallization is the method employed to get metal of very high purity i.e. ultrapure samples of Ge, Si, B, Ga etc.
This method is based on the fact that impurities are more soluble than the pure metal in the melt.
