There are three main methods of mining (extraction) Aajazha salt can be as follows
1) the method of mining dry
(Dry Mining Method)
Where whereby mining rock salt relatively near the Earth's surface, and this method allows exploiting some (45-65%) of crude, also known this manner in a room and props (Room and Pillar Mining Method ).
2) the method of mining Mahloly
(Solution Mining Method)
In this way the extraction of salt sediments deep where they are landing Onpoptan (small tube centralized inside the tube, the largest) in the wells and pumping fresh water in the tube central Iveb water, some salt component solution was too salty and rushes this solution to the surface through the tube and transported to the external tanks equipped for industrial evaporation process to form a solid salt.
3) the method of solar evaporation
(Solar Salt Mining Method)
In this way the extraction of salt from the coastal and inland marshes using evaporation phenomenon where the sun is where immersion basins adjacent to the marsh and left to evaporate, then sweep away the salt. Rough handling: handles rock salt is Almttbak grinding and crushing of the desired size, and the salt deposits rocky Almttbakh dealt with in a manner (Sortex Process) with or without a way of gluing thermal (Thermoadhesive process) to raise the degree of concentration of sodium chloride from (97%) to (99%) and more , the pure raw addresses the way crystals small size (10 mesh) where they are thawed raw at elevated temperatures and then leave to cool gradually Vtaatersb pure salt crystals. Uses: The salt for many countries a source of national wealth because of the importance of this salt in various fields of life where humans salt is used directly and indirectly in the fields of multiple.
Below is the most important uses of salt:
1) the production of chemicals used in various industries as diverse as Soda Ash (sodium carbonate), caustic soda (sodium hydroxide, chlorine, sodium, hydrogen, hydrochloric acid).
2) is used as a spice and preservative in food processing and human and animal.
3) is used as a factor reducing the freezing point of water to melt the snow and ice.
4) is used in the processing of certain raw materials, such as metal ores elements.
5) is used in metallurgy, oil and chemical industries for the production of soap, dyes and leather tanning.
6) is used in the refractory industry for the production of ceramic tiles.
7) is used in agriculture as an insecticide, and in the dairy industry in addition to its uses in the manufacture of drugs.
8) used mining salt is produced as warehouses for strategic materials such as hydrocarbon.
9) the latest use of salt is to bury nuclear waste in rock salt mines.
The ratio of the use of salt in melting snow on the highways in the United States at the end of the year (2006), about (68%) of the total uses, and (12%) in water treatment, and (8%) in the production of chemicals, and (6%) in food preservation, and (6%) in agro-industries.
