چکیده انگلیسی


• Integration technology is applied to manufacture sodium-free lithium chloride.
• The preliminary separation showed sodium decreases to below 0.187% in brine.
• Novel ion exchanger showed excellent separation and purification performance.
• The total yield was 86.16%, and the sodium removal reaches 99.993%.

Process assessment experiment was conducted to investigate the applicability of integration technology (CCI, concentration, cooling and ion exchange) to manufacture sodium-free lithium chloride from salt lake brine. The preliminary separation process of sodium from brine, using evaporating concentration by adding surfactant, showed the amount of sodium in brine decreases to below 0.187%. Then, brine was further cooling separation process which was characterized in that the ammonia is added in order to decrease the solubility of NaCl. The purification of lithium chloride from cooling brine was then conducted with a novel separation process which was designed by a novel ion exchange method using inorganic ion-exchanger Li1.4Cr0.4Ti1.6 (PO4)3. The total yield of LiCl with the present purification process was 86.16%, and the sodium concentration in the supernatant is 0.0005 wt.%.
