摘要： This invention relates to treated geothermal brine compositions containing reduced concentrations of lithium, iron and silica compared to the untreated brines. Exemplary compositions contain concentration of lithium ranges from 0 to 200 mg/kg, concentration of silica ranges from 0 to 30 mg/kg, concentration of iron ranges from 0 to 300 mg/kg. Exemplary compositions also contain reduced concentrations of elements like arsenic, barium, and lead.

摘要： A solid particulate composition useful in extracting a lithium salt from aqueous solutions, the composition comprising lithium, metal atoms, oxygen atoms, and at least one anionic species (X) selected from halide, nitrate, sulfate, carbonate and bicarbonate, all in a framework structure, wherein said metal atoms are selected from at least one of oxophilic main group metal and oxophilic transition metal atoms, provided that, if the metal atoms comprise aluminum atoms, then at least 10 mol % of said aluminum atoms are substituted with at least one metal atom selected from said at least one oxophilic main group and oxophilic transition metal atoms, other than aluminum, and wherein said lithium is present in said composition in an amount less than a saturated amount in order to permit extraction of lithium salt. Methods for extracting and recovering a lithium salt from an aqueous solution by use of the above-described composition are also described.

摘要： This invention relates to a method for the preparation of lithium carbonate from lithium chloride containing brines. The method can include a silica removal step, capturing lithium chloride, recovering lithium chloride, supplying lithium chloride to an electrochemical cell and producing lithium hydroxide, contacting the lithium hydroxide with carbon dioxide to produce lithium carbonate.
