Realizing the demand of low sodium salt which is commonly prepared by homogeneous mixing of NaCl and KCl, CSIR-CSMCRI has developed a cost effective process for the production of low sodium salt using the bittern, the mother liquor left out after production of salt in solar salt works. The process involves the desulphatation of bittern using cheap agents like distiller waste liquor of soda ash plants and processing the desulphated bittern for the recovery of low sodium salt via the intermediate product carnallite.
