4.2.2 Solvent extraction. Solvent extraction uses a two-phase system to separate lithium from the leached cathode material. 98–102 It uses relative solubility to separate ions from polar and nonpolar liquids. Nonpolar extractants are mainly used to separate valuable metals (Co, Ni, Mn), and lithium is separated from the stratified solution.
