1.05.2018· The extraction efficiencies with two kinds of additive (CaO and NaOH) were compared. • Up to 93.30% Li was extracted using Na 2 SO 4 solution with additive of CaO.. Extraction was based on ion-exchange between Li + from β-LiAlSi 2 O 6 and Na + from Na 2 SO 4.. Na 2 SO 4 in mother solution could be recycled to leaching process for reuse.

This invention relates to the separation of lithium from lithium-containing materials, primarily ores such as hectoritic montmorillonite, having about 0.02 to 2.0 percent lithium by weight. The process comprises reducing the particle size of the material to less than about 500 microns; slurrying the particles with an aqueous base consisting of carbonates or hydroxides of sodium or potassium
