Vedclass · Answer

(D) Zone refining is based on the principle that the impurities are more soluble in the molten state of the metal than in the solid state. $A$ circular mobile heater is fixed at one end of a rod of the impure metal. The molten zone moves along with the heater as it is moved forward. As the heater moves forward,the pure metal crystallises out of the melt,and the impurities pass into the adjacent molten zone,eventually reaching the end of the rod.
