초록

본 논문은 마그네슘 함량이 매우 높은 특징을 갖는 볼리비아 우유니호 염수로부터 리튬을 회수하는 공정의 설계에 필요한 기초자료를 얻을 목적으로 수행되었으며, 농축된 용액에 수산화칼슘의 첨가하여 수산화마그네슘을 침전시키는 반응에 있어서 용존 이온의 농도에 미치는 반응온도, 반응시간, pH 등 제 인자들의 영향을 조사하였다.

Abstract

This study was conducted to obtain the basic data for designing the lithium recovery process from the "salar de Uyuni" inBolivia. For this study, the mock brine which has the similar chemical composition with the brine of "salar de Uyuni" was prepared,and the effects of reaction factors such as temperature, time, pH and so forth on the precitation reaction of magnesiumhydroxide were investigated.
