    Exploitation of sambhar lake bitterns
    (2011-11-23T09:36:49Z) Seshadri, K.; Buch, S.D.
    A process for recovering sodium solphate, sodium chloride and sodium carbonate from hquid and solld bitterns and sub-standard salt,worked out on the basls of phase rule studles, is described. it consists of the following steps:(1)elimination of algae from the liquid bittern or aqueous extracts of solid bitterns by chlorine treatment;(2)adjustment of the composition of the solution and chilling it to 0'C.;(3)separation of Na2SO4.10H2O by centrifuging;(4)dehydration and purification of sodium sulphate by solar heat;(5)recovery of sodium chloride by solar evaporation of desulphated llquor until the liquid reaches 10 per cent sodium carbonate strength;and(6)carbonation of the desalted liquor for the recovery of sodium carbonate as bicarbonate.

    Exploitation of sambhar pan crust
    (2011-11-23T09:53:45Z) Seshadri, K.; Buch, S.D.
    Tree method based on solubility data have been worked out for the recovery of sodium sulphate from the sambhar lake pan crust. ninety per cent of sodium sulphate present in the crust is recovered as technical grade quality sodium sulphate by the chilling process, 65-73 per cent by adding solid sodium chloride at 50'C.to the solution prepared from the crust and 75-80 per cent from the upgraded crust obtained by digesting it with water.
