Modern salt extraction is conducted in several main ways. The first and best known method – extraction of salts from sedimentary rocks. This method is called mine. With this method, is mined rock salt. It is a firm and solid monolith. Under the influence of pressure and high temperature, it softens. In those places where the monolith rises closer to the surface of the earth, it is mined. It makes using a special technique called coleambally.salcombe
Another method of salt production, which is quite famous, is the vacuum method. To obtain a salt with this method, it is necessary to boil from the brine. To get the brine well is being drilled in a salt formation in the layers of the earth, then fill it with fresh and clean water. There is this water dissolves salt. When the concentration of the salt becomes the desired concentration, it is pumped by means of pumps. Obtained in this method salt is the high-quality and clean.
Using the lake way salt is extracted samostatnou. This salt is mined in salt lakes, which have significant layers of salt. Sedimentary salt require a thorough cleaning before using it in food industry.dobychnoe
In addition to those methods, which were listed above, there are others. Among them: freezing, career method and evaporation. The process of salt production, depending on the method, is time-consuming. Produced a special technique and device to produce it the most effective method.
