Abstract

Sodium chloride is recovered from substances containing it, such as rock or sea salt, by extracting with liquid ammonia, separating insoluble substances, and evaporating the solution obtained. The whole of the sodium chloride may be recovered by evaporating the solution to dryness, or a part may be recovered by heating to 30 DEG C. and the mother liquor be used to extract more sodium chloride. Extraction is preferably effected at a temperature between 0 and -- 10 DEG C., as below -- 10 DEG C. a less soluble ammonium compound of sodium chloride, NaCl.x.NH3, is formed. The recovered salt is completely freed from ammonia by heating to 150-200 DEG C. under reduced pressure. The solution of sodium chloride in liquid ammonia after evaporation to remove excess ammonia may be treated with water to obtain a solution for use in the production of sodium bicarbonate.
