The refining method used when the metal and the impurities have low and high melting temperatures,respectively,is

$A$ low boiling point metal contains a high boiling point metal as an impurity. The correct refining method is:

Explain the electrolytic refining of metals.

In the electrolytic refining of metals,the electrolysis of an aqueous solution of its complex salt is performed using an impure metal as the anode and a strip of pure metal as the cathode. This method cannot be used for the refining of which of the following metals?

Which method of purification is represented by the following equation?
$Ti_{(s)} + 2I_{2(g)}$ $\xrightarrow{523 \ K} TiI_{4(g)}$ $\xrightarrow{1700 \ K} Ti_{(s)} + 2I_{2(g)}$

The poling process is used when the metal contains:
