摘要： A process for extracting lithium from lithium-bearing salt brines including: (i) subjecting a feed brine to a primary evaporation step using mechanical evaporators, to form a first concentrated brine and sodium chloride; (ii) separating the sodium chloride in a salt removal step; (iii) reacting lime with the first concentrated brine in a liming step to precipitate out and discard magnesium and sulphate ions and other contaminants and to form a limed brine; (iv) subjecting the limed brine to a secondary evaporation step, to form a second concentrated brine and precipitating calcium chloride; (v) separating the calcium chloride from the second concentrated brine; (vi) reacting sodium sulphate with the second concentrated brine to precipitate out and discard calcium sulphate, to form a lithium-rich brine; (vii) reacting soda ash with the lithium rich brine thereby forming a precipitate of lithium carbonate; and (viii) separating the lithium carbonate.

摘要： Significant amounts of soluble fluoride, known to create problems in processes requiring high quality grade calcium chloride, are removed from calcium chloride solution using hydroxyapatite as a removal mechanism. Under acidic conditions, calcium chloride solution is purified to about less than 10 ppm fluoride, significantly, to less than 1 ppm fluoride. At least 0.1 weight percent hydroxyapatite and concentrated hydrochloric acid are added to calcium chloride solution and slurried to remove fluoride and create a highly purified calcium chloride solution, substantially free of fluoride.

摘要： CALCIUM AND SODIUM CHLORIDES ARE PRODUCED BY EVAPORATING THE DISTILLATION LIQUID RESULTING FROM THE AMMONIA SODA ASH PRODUCTION PROCESS. THIS LIQUID IS CLARIFIED AND INTRODUCED INTO THE EVAPORATORS TO MIX WITH A CONCENTRATED CALIUM CHLORIDE SOLUTION CONTAINED THEREIN, THE CONCENTRATION OF CALCIUM CHLORIDE IN SUCH A MIXED SOLUTION BEING MAINTAINED AT 28-45 WT. PERCENT. IN THE PROCESS ACCORDING TO THE METHOD DISCLOSED HEREIN, STEAM IS PASSED CONSECUTIVELY THROUGH ALL THE EVAPORATORS OF THE PLANT.

THE APPLICATION OF THE PROPOSED METHOD PRACTICALLY PRECLUDES THE FORMATION OF GYPSUM DEPOSITS ON THE HEATING SURFACES OF THE EVAPORATORS.

摘要： Purified barium salts essentially devoid of strontium impurities, e.g., highly pure barium carbonate, are produced by liquid/liquid extracting an aqueous solution of impure barium values with an organic solvent medium which comprises at least one water-insoluble carboxylic acid, phosphonic acid monoester, or substituted 8-hydroxyquinoline extractant. The mixture of extraction is separated into a purified aqueous phase containing the desired barium salt values and an organic phase containing the impurity values sought to be removed.
