Extraction of lithium carbonate from brine or minerals and/or clay, including boron precipitation using barium salts, through a free organic extraction process, the leachate reacts with alkaline hydrogen and magnesium precipitation and reacts with carbonate. Lithium carbonate precipitates sodium, separates and dries lithium carbonate.
