Theoretical foundations of technology for producing lithium carbonate of battery quality by the ammonia method have been developed. This technology is based on the precipitation of lithium carbonate from an aqueous solution of lithium chloride by its direct contact with a gaseous mixture of NH3 and CO2 in a 2 : 1 ratio, followed by NH3 reproduction by the decomposition of ammonium chloride with calcium hydroxide, which is a byproduct of interactions in the LiCl−NH3–CO2−H2O system. The applicability of the ammonia method for obtaining battery-quality Li2CO3 from sulfate, nitrate, and mixed lithium solutions has been shown.
