Abstract
Sea bittern left over after the recovery of common salt from sea water, at present allowed to go waste is rich in potassium chloride which can be recovered from the bittern by fractional crystallization. the salt as such, without purification,finds use in the preparation of mixed fertilizer. crops like potato, clover, tobacco, beet, etc. do not tolerate chloride and in these cases chloride-free potassium sulphate is employed.
