NOVELTY - The method involves supplying silica-lean lithium chloride containing solution to a lithium chloride capture step that captures lithium chloride from silica-lean lithium chloride containing stream. Lithium chloride is recovered from the lithium capture step to produce a lithium chloride rich stream. The lithium chloride-rich stream is supplied to an electrochemical cell, where the electrochemical cell is maintained at conditions sufficient to produce a lithium hydroxide-rich solution, and the lithium hydroxide-rich solution is in contact with carbon dioxide to produce lithium carbonate.    USE - Method for preparing lithium carbonate from a lithium chloride containing solution i.e. geothermal brine (claimed), for chemical and pharmaceutical industries.    ADVANTAGE - The method enables supplying lithium chloride containing solution to silica management step, which operates to significantly reduce an amount of silica that is present in the lithium chloride containing solution such that silicate precipitate and silica-lean lithium chloride containing solution are produced. The method enables an anode to be designed with dimensionally stable anode element for allowing reduced power consumption. The method enables producing lithium carbonate product stream and sodium chloride brine solution to attain improved product quality in a cost-effective manner. The method enables removing interfering ions from brines for production of lithium carbonate.
