1. The rock salt is grinded.
2. The material is mixed with water and stirred.
3. The liquid is filtered.
4. Sodium chloride being soluble passes the filter.
5. By heating the water is evaporated and crystallized NaCl obtained.
Boil the water so that the salt can recrystallize thus separating the salt from water (evaporation).
So the salt dissolves
by separating rock salt from water .
Desalination
Evaporation, boiling or distillation will all result in separating the salt from the water.
The scientific name for separating salt from water is "desalination." This process involves removing salt and other impurities from seawater or brackish water to make it suitable for drinking or other uses.
EvaporationIf your intent is to have both products--salt and water, then the process is called distillation, in which the water is boiled away and collected.
Iron is a magnet so it could be used for separating bits of metal from crushed up rock? True for iron, and separating bits of iron. But iron sulphate is not magnetic.
It's really try it and you will find out relative
This depends on the grinding and sieving process.
