Method which is based on differeence in solublity of impurities in molted and solid state of metal

Assertion : Zone refining is based on the solubilities of impurities in the molten state than in the solid state of a metal. Statement : Pure metal oxide is obtained in zone refining.

(v) Impurties are more soluble in the melt than in the solid state of the metal.

(v) Impurties are more soluble in the melt than in the solid state of the metal.

The method of concentrating the ore which makes use of the difference in density between ore and impurities is called

The method of concentrating the ore which makes use of the difference in density between ore and impurities is called

Metals of high purity are obtained by zone refining. Impurities are more soluble in melt in pure metal.
