Abstract:
(EN) This method for dissolving a lithium compound comprises bringing a lithium compound into contact with water or an acid solution and supplying carbonate ions to the water or acid solution to generate carbonic acid, and reacting the lithium compound with the carbonic acid and causing lithium hydrogen carbonate to be generated.
(FR) Cette invention concerne un procédé de dissolution d'un composé de lithium comprenant l'amenée du composé de lithium en contact avec de l'eau ou une solution acide et l'introduction d'ions carbonate dans l'eau ou la solution acide pour générer de l'acide carbonique, et la réaction du composé de lithium avec l'acide carbonique pour provoquer la génération d'hydrogénocarbonate de lithium.
(JA) この発明のリチウム化合物の溶解方法は、水もしくは酸性溶液にリチウム化合物を接触させるとともに、前記リチウム化合物とは別に前記水もしくは酸性溶液に炭酸イオンを供給して、炭酸を生じさせ、リチウム化合物を前記炭酸と反応させて炭酸水素リチウムを生成させるものである。
