The solution of the mined rock salt (NaCl) is called brine.
If a solution containing rock salt is boiled, and the solvent evaporates you will be left with rock salt as the precipitate.
By evaporating the water of the solution and condensing it.
This is a supersaturate solution.
It will be saturated salt solution with salt crystals at the bottom of the container.
1. Grinding of the rock salt. 2. Dissolving of the rock salt in water. 3. Filtering of the solution. 4. Repeated processes of crystallization/recrystallization.
This depends on the quality of salt from a specified mine.
Rock Salt
Rock salt is salt. The difference is that rock salt is impure, literally "dirty" and not suitable for eating consumption.
Rock salt is ground, dissolved in water, the solution is filtered and this solution is refined by successivelyprocesses of crystallization/recrystallization, to obtain sodium chloride (table salt) 99,99 %; and finally this salt is iodized and some anticaking substances are added.
Rock salt is sodium chloride; the mineral has the name halite.
