Title (EN) METHOD FOR MANUFACTURING HIGH-PURITY CARBONATED LITHIUM
(FR) PROCÉDÉ DE FABRICATION DE LITHIUM CARBONATÉ DE HAUTE PURETÉ
(KO) 고순도 탄산리튬 제조방법
Abstract: front page image
(EN) The present invention relates to a method for manufacturing high-purity carbonated lithium. Particularly, the method for manufacturing the high-purity carbonated lithium includes: removing magnesium and boron; separating and removing the remaining magnesium and boron; performing a powder concentration process which forms a powder through spray-drying; cleaning the powder to concentrate lithium; and carbonating the lithium ions using sodium carbonate (Na2CO3).
(FR) La présente invention concerne un procédé de fabrication de lithium carboné de haute pureté. En particulier, le procédé de fabrication du lithium carbonaté de haute pureté inclut : l'élimination du magnésium et du bore ; la séparation et l'élimination du reste de magnésium et de bore ; la réalisation d'un procédé de concentration de poudre qui forme une poudre grâce à un séchage par pulvérisation ; le nettoyage de la poudre pour concentrer le lithium ; et la carbonatation des ions lithium en utilisant du carbonate de sodium (Na2CO3).
(KO) 본 발명은 고순도 탄산리튬 제조방법에 관한 것으로 보다 상세하게는 염수로부터 탄산리튬을 제조하는 방법에 있어서, 마그네슘 및 붕소를 제거하는 단계; 잔존하는 마그네슘 및 칼슘을 분리 제거하는 단계; 분무건조를 통해 분말을 형성하는 분말 농축화 단계; 상기 분말을 세척하여 리튬을 농축하는 단계; 및 탄산나트륨(Na2CO3)을 이용하여 상기 리튬이온을 탄산화하는 탄산화 단계를 포함하는 고순도 탄산리튬 제조방법을 제공한다.
