  • Method for obtaining concentrated brine of minimum impurity content from brine found in natural salt flats and salt marshes, said method having minimum environmental impact and maximum lithium recovery
    Patent number: 11920211
    Abstract: A procedure of minimum environmental impact and maximum lithium recovery for obtaining concentrated brines with minimal impurity content from brines that embed natural salt flats and salt marshes, the procedure wherein the following stages are comprised: a) building fractional crystallization ponds by solar evaporation; b) filling the ponds with natural brine; c) initially pre-concentrating natural brine to the maximum possible lithium concentration in the liquid phase without precipitating lithium-containing salts; d) cooling the pre-concentrated brine obtained in c) ensuring maximum precipitation of salts containing sulfate anion; e) chemically pre-treating the liquid phase of brine separated from precipitated salts by cooling to minimize sulfate anions in the liquid phase after cooling; f) finally pre-concentrating the pre-treated liquid phase to the maximum possible lithium concentration in it without precipitating lithium-containing salts; g) chemically treating the liquid phase of brine separated from p

  • Process for recovering lithium from a brine
    Patent number: 8641992
    Abstract: There is disclosed herein a process for recovering lithium from an impure natural or industrial brine, the process comprising adjusting the pH of a feed brine containing lithium to a value of no less than 11.3 and separating the waste solids and a solution containing lithium values. The solution may be further concentrated and treated to obtain lithium carbonate and a lithium chloride solution suitable for obtaining electrolytic grade lithium chloride.
