Salt production
There are several ways in which salt is mined. One of the oldest is the sedimentary, or basin, method. On the seashore in the autumn they dig a pond, which is filled with water using a specially created ditch. After waiting for clay and sand to settle on the bottom of the pool, the water is transferred to the second pool, and by the spring to the third. Evaporation of water leads to an increase in salt concentration.
As a result, in the last reservoir the salt forms a rather thick layer. Using a salt harvester, the product is taken out of the pool and laid in hills 10-15 meters high. It remains to rinse the crystals and load them into railway cars.
Another way is called mine. Huge salt masses are found underground, which are crushed using special equipment and raised to the surface. Then the salt is cleaned of impurities and dust and packaged in small boxes. The process of extraction of rock salt is fully mechanized.
Extra grade salt is produced in salt mills using the vacuum method. Fresh water, which dissolves the mineral, is injected into the salt layer that lies underground. Then the solution is raised, subjected to purification and sent to vacuum chambers. Here the brine boils and evaporates actively. Precipitated crystals are passed through a centrifuge to separate the remaining liquid. As a result of this process, you can buy finely ground salt in stores.
