Abstract: The invention relates to a method for producing a highly pure lithium salt using lithium carbonate. Said method comprises the following steps: A: treating a mixture comprising lithium carbonate and water with CO2 to produce an aqueous mixture containing lithium hydrogencarbonate; B: passing the aqueous mixture containing lithium hydrogencarbonate through an ion-exchange module; C: precipitating out the lithium carbonate from the aqueous mixture containing lithium hydrogencarbonate obtained in step B after treatment with the ion-exchange module and D: reprocessing the precipitated lithium carbonate or converting the precipitated lithium carbonate into another highly pure lithium salt.

Abstract: Alkali metal nitrates are prepared by supplying the anode space of an electrolysis cell, separated from the cathode space by a perm-selective cation exchange membrane, with alkali metal chloride solution and at the same time supplying the cathode space with a nitric acid/alkali metal nitrate solution whose alkali metal nitrate concentration is not less than 10% by weight and whose HNO3 concentration is of from 0.1 to 10% by weight, and withdrawing from the cathode space a solution whose pH does not exceed 5.
