Sambhar Lake brine contains predominantly sodium chloride, sodium sulphate and sodium carbonate. The mutual solubility relationships existing in the system NaCl−Na2SO4−Na2C03−H20 have been projected isothermally at 0°, 20°, 35°and 100°C, indicating various solid phases formed. The theoretical recoveries have been calculated by plotting the course of change in brine and bittern compositions on the respective phase diagrams. Various steps to recover each of the constituents have been worked out using these diagrams.
