Salt can be recovered from its solution by crystallization.

Explanation:

Crystallization is the process of formation of solid crystals precipitation from a solution. It is Solid- liquid separation.

By using ' crystallization technique, ' salt can be recollected from its solution. This technique is better than ' evaporation ' because it removes dissolved impurities which are present in the solution.

But in the evaporation process we cannot remove the dissolved impurities present in the solution.
