Industrial Rock SaltProduct Application:
The salt mined by underground mining or mining is the rock salt. Drilling draws salt from underground natural brine and salt from the production of underground rock salt. Has a long history of production (see the history of salt production technology). The production process is divided into two parts: mining and salt production. The underground natural brine is extracted by the method of extraction, gas lift or submerged brine pump; the rock salt is mined and drilled (dry mining) and water-soluble mining according to the geology, occurrence conditions and grade of the deposit. The salt is used for a long time in a round pot and a pan. Since the end of the 19th century, advanced technologies such as vacuum evaporation, hot pressure evaporation, vacuum and hot pressing have been used.
