Explanation:
On an industrial scale, salt is produced in one of two principal ways: the evaporation of salt water or by mining. Evaporation can either be solar evaporation or using some heating device.
But in ancient days salt was prepared in a traditional way.
The ocean or sea water was stored in the pits which are beside the sea. The water will get evaporated in the presence of sunlight. After that the crystallisation will take place. Then the salt was prepared. In ancient days they will not use any machines and all these steps will be done by humans.
