Well salt processing technology

The raw materials used in the production of mine salt in China are generally divided into two categories: rock salt artificial brine and natural underground brine. The main methods of brine treatment are air blowing method, tower furnace degassing method, strip frame method, chemical method, lime (or caustic soda) -glauber method, lime- gypsum method, yellow and black (rock) halogen mixing method, lime- More than 10 kinds of soda ash method, lime-glauber-carbonization method, caustic soda-soda ash-chloride method.
The salt-making process has several kinds of raw materials, product uses, and energy production methods, but there are two main processes: evaporation crystallization, dehydration and drying: vacuum evaporation, centrifugal dehydration, and boiling drying are used in China. Different components of brine take different salt production processes, in addition to the production of salt, while recovering products such as gypsum and thenardite.
