Answers
Answer:
The zone refining is a procedure for the purging of a crystalline material and particularly a metal wherein a liquid locale goes through the material to be refined, grabs polluting influences at its propelling edge, and afterward enables the decontaminated part to recrystallize at its contrary edge.
During the time spend of refining, a round portable warmer is fixed toward one side of a pole of debased metal. At that point, the end with the pollutions is cut off.
Answer:
Principle - The impurities in the molten state are more soluble than in the solid state of the metal . Method - In this method , a circular mobile heater is fixed at one end of a rod of the impure metal . The molten zone moves along with the heater which is moved forward .
