Rock salt is ground, dissolved in water, the solution is filtered and this solution is refined by successively
processes of crystallization/recrystallization, to obtain sodium chloride (table salt) 99,99 %; and finally this salt is iodized and some anticaking substances are added.
What else can I help you with?
Why do we get pure salt from rock salt?
Pure salt is obtained from rock salt through a process called evaporation. Rock salt contains impurities and other minerals that are removed when the salt is dissolved in water and then evaporated, leaving behind pure salt crystals. This process helps to separate the salt from any impurities present in the rock salt.
How do you get pure water from a salt and water solution?
By evaporating the water of the solution and condensing it.
Is rock salt as pure as table salt?
Generally rock salt is more impure than table salt.
Can rock salt be used as table salt?

What is a pump housing?

This is possible only after the determination of impurities in the rock salt.
What is the luster of rock salt?
The luster of rock salt is Vitreous (glassy)
How do you get the percentage of pure salt in rock salt?
This percentage is determined by chemical analysis; for some salt mines this percentage is over 99 %.
How would you separate rock salt to obtain salt crystals and pure dry sand?
To separate rock salt into salt crystals and pure dry sand, first dissolve the rock salt in water, creating a saltwater solution. Next, filter the mixture to separate the sand, which will remain on the filter paper, from the saltwater solution. Finally, evaporate the water from the saltwater solution to obtain pure salt crystals, leaving behind the dry sand collected from the filtration process.
What is a possible danger of obtaining rock salt by mining?
Two problems exist: - Collapse of the mine roof - Flooding the mine and salt dissolution
