Abstract

Abstract:

The salt-lake brine with high lithium concentration was used as raw material,and SO₄^2- in this brine was removed by chemical precipitation method by adding calcium chloride as precipitant.The effects of raw material ratio（ratio of substance amount of Ca²⁺/SO₄^2-),feeding mode,feeding time,reaction time,stirring speed and reaction temperature on the desulfuriza-tion rate were investigated in detail.Meanwhile,the entrainment loss rate of lithium under different operating conditions and the form of lithium complex salt formation were emphatically studied.The research results showed that the optimum conditions for desulfurization were below：the ratio of raw materials was 1.2,the react temperature was 25 ℃,the feeding time was 24 min,the stirring speed was 150 r/min and the reaction time was 60 min.In this experiment condition,the removal rate of SO₄^2- in brine could reach 99.02%,the entrainment loss rate of lithium was 27.71%.The morphology of the precipitation products could be obtained by SEM.The results of XRD showed that the loss of lithium was mainly in the form of Li₂SO₄·H₂O and LiAl₂（OH）₇（H₂O）₂ in the process of separating SO₄^2-.
