Lithium carbonate is the primary product of the lithium extraction process and is an important
compound for the battery making industry. A major step in the conventional sulfuric acid
extraction of lithium from mineral ore is the precipitation of lithium carbonate from lithium
sulfate media by sodium carbonate addition. Because of the high solubility of lithium
carbonate in water and challenges with separating and removing sodium sulfate from the
product, this step has a low lithium recovery efficiency as lithium carbonate, and it is difficult …
