How do they seperate table salt (NaCl) from seawater

[easypeasyac]

Sorry maybe it is stupid question but unfortunately I couldn't find the answer.

I know that sea water is evaporated under the sun and salt is obtained.

However, this resulting salt contains not only sodium chloride but also many other salts such as MgCl₂, KCl, CaCl₂... How do they separate sodium chloride from these salt mixture and obtain pure table salt?

Thank you.

They use different solubilities, Fraction cristallisation.
