lake salts. The SALEX-F process is required for upgrading of rock salts. Salt upgrading helps to solve the problems associated with contaminated sludge and purge disposal. The overall salt consumption, the total investment and the operating cost are reduced. With pure salt of constant composition the brine plant operation becomes easier. This process is called liquefaction. Sodium hydroxide often contains leftover salt in the solution. The mixed sodium hydroxide and brine solution is heated to evaporate water. This makes the solution more concentrated and the salt precipitates out of the solution and is recovered to make more brine. The sodium hydroxide is concentrated up to 50%.
