中文摘要: 对高钙、高锂、低镁锂比(Mg/Li:0.02)国外阿根廷某盐湖卤水进行钙、镁、锂深度分离的工艺研究。采用两步法去除溶液中的Ca2+、Mg2+:首先加入硫酸钠生成硫酸钙沉淀除去大量的Ca2+,后加入氢氧化钠形成氢氧化镁和氢氧化钙除去少量的 Ca2+、Mg2+;分别考察了物料比、反应温度、加料时间、加料速率、pH 值对卤水除杂效果的影响因素。实验结果表明:在反应温度60 ℃、硫酸钠用量为1.3、加料速率6 mL/min、反应时间70 min 条件下,溶液中 Ca2+ 的脱除率为96.22%,Li+ 的损失率为1.44%;在 pH 为14、10 mol/L NaOH、反应时间50 min、反应温度50 ℃、加料速率为8 mL/min条件下,最终溶液中 Ca2+ 脱除率为99.75%,Mg2+ 去除率为100%,Li+ 的损失率为0.04%;实现了钙镁离子的深度去除,为后续工序制备碳酸锂创造了有利的条件。

Abstract:Process Study of Calcium, Magnesium, and Lithium Deep Separation for high calcium, high lithium, and Low Magnesium Lithium Ratio (Mg/Li:0.02) Foreign Argentine Salt Lake Brine. A two-step method was used to remove Ca2+ and Mg2+ from the solution: first, sodium sulfate was added to generate calcium sulfate precipitation to remove a large amount of Ca2+, and then sodium hydroxide was added to form magnesium hydroxide and calcium hydroxide to remove a small amount of Ca2+ and Mg2+. The influences of the material ratio, reaction temperature, feeding time, feeding rate, and pH value on the impurity removal effect of brine were investigated respectively. The experimental results showed that at the reaction temperature of 60 ℃, the amount of sodium sulfate was 1.3, the feeding rate was 6 mL/min, and the reaction time was 70 min, the removal rate of Ca2+ in the solution was 96.22%, and the loss rate of Li+ was 1.44%; at pH 14, 10 mol/L NaOH, reaction time of 50 min, reaction temperature of 50 ℃, and feeding rate of 8 mL/min, the final removal rates of Ca2+ and Mg2+ in the solution were 99.75% and 100%, respectively, and the loss rate of Li+ was 0.04%. The deep removal of calcium and magnesium ions was achieved, which created favorable conditions for the preparation of lithium carbonate in subsequent processes.
