What is the salt?
In the course of history, salt holes were used to dissolve the Halit underground bearings and their extraction in the form of brine. Typical salt consists of a pipe that has been drilled into a salt bed or dome, water, pumping equipment and sometimes infrastructure needed for evaporation. The process of extracting the salt halit usually involves pumping water into a deposit that can dissolve it into the brine. This solution can then be pumped to the surface and either sold in solution or exposed to the evaporation process, resulting in dry, granules. Salt mining evidence has been discovered since the fourth century BC in China, although it is likely that the process existed earlier. In ancient China, salt bearings were usually achieved by bamboo drill control deep into the ground. Given the difficulty in extraction of salt by means of early technology and the widely distinguished nature of Halita bearings and salt domes, it was an important commodity throughout the early human history.
Most salt beds and dome lies about 500 to 1,000 feet (150 to 1,500 meters) below the surface and natural salts are one of the ways to localize new places for salt. In these places, the Arteasian wells coincide with the salt domes and the water dissolves some salt when it penetrates the surface. By drilling in the nearby area, the pipeline can be extended to the salt dome to facilitate the extraction process. When water is pumped into a salt bed or dome, it will tend to dissolve the mineral into the brine in the brine solution inside the emptiness known as the salt cave. The brine can then be exhausted from the cave for evaporation to salt crystals or use in various industrial industrial gradients.
brine from a well of salt is often evaporated in place. This was traditionally achieved by methods of ceramics or iron pelvis, although various modern techniques are now used. In other cases, the brine can be fed toa plant for processing outside the workplace. Some chemical plants also use captured salt wells in place to conveniently obtain a salt solution for different chemical processes. One use for captured salt is the chloralkali process, which uses electrolysis to remove hydrogen, chlorine and sodium hydroxide from the brine.
