METHOD FOR THE ELECTROLYTIC PRODUCTION OF LITHIUM HYDROXIDE-CONTAINING AQUEOUS SOLUTIONS FROM CONTAMINATED AQUEOUS DILUATES CONTAINING LITHIUM

摘要

The invention relates to a process for the preparation of lithiumhydroxidhaltigen aqueous solutions in which a contaminated, lithium-containing, aqueous diluate is electrodialytically separated by at least one electrodialysis cell in a lithiumhydroxidhaltiges aqueous concentrate and an acid, thereby diluate, concentrate and acid in three independent process streams in a continuous cycle are guided, wherein at least one of the three process streams is continuously directed through a unit for filtering the process stream and an apparatus for the production of lithiumhydroxidhaltigen aqueous solutions.
