| Outline of Final Research Achievements |
Hybrid process for selective recovery of lithium and boron from geothermal water together with direct production of lithium hydroxide and boric acid was developed by combining the chromatographic recovery of lithium and boron using the adsorbents and the bipolar electrodialysis process. The study was conducted (1) Recovery of lithium tetraborate from geothermal water using lithium adsorbent and boron adsorbent, (2) Separation and recovery of lithium tetraborate from geothermal water using an adsorption column connected with a lithium adsorption column and a boron adsorption column, and (3) simultaneous and direct production of lithium hydroxide and boric acid using a bipolar electrodialysis method from lithium tetraborate recovered from geothermal water.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の学術的意義は、地熱水から高付加価値なレアメタル資源を同時採取可能な分離回収プロセスを開発するとともに、我が国オリジナルの技術であるバイポーラ電気透析法を用いた生成物への直接変換と濃縮プロセスを組み合わせたハイブリッドプロセスを開発したことである。また、社会的意義は、未利用資源である地熱水から国産のレアメタルを回収することによって我が国の資源確保問題の解決に貢献できることである。
