Abstract
In this work, a solvent extraction process for Ca2+ and Mg2+ removal from Li+ concentrated solution consisted of 30 g/L Li+, 1.5 g/L Ca2+ and 1.5 g/L Mg2+ was proposed, using di-(2-ethylhexyl) phosphoric acid (D2EHPA) as extractant. The extraction process was a cation exchange mechanism, and the extraction sequence was Ca2+ > Mg2+ > Li+ > Na+. Under the optimum condition of 66% saponification degree, 3/2 phase ratio and three-stage extraction,...
