  • PREPARATION OF LITHIUM CARBONATE FROM LITHIUM CHLORIDE CONTAINING BRINES
    Publication number: 20200399137
    Abstract: This invention relates to a method for the preparation of lithium carbonate from lithium chloride containing brines. The method can include a silica removal step, capturing lithium chloride, recovering lithium chloride, supplying lithium chloride to an electrochemical cell and producing lithium hydroxide, contacting the lithium hydroxide with carbon dioxide to produce lithium carbonate.
