A technique process to remove impurities of calcium and magnesium from the leaching solution obtained after roasting plus leaching process of a sort of lepidolite was studied, and the effects of several factors on washing effect, including amount of sodium carbonate, solution pH, time and temperature of reaction and washing conditions, were all investigated. The results show that removal rates of calcium and magnesium can reach 99.9% and 93.1%, respectively, by adding sodium carbonate as precipitant at an amount of 2.21 mol/L, with pH of solution at 8.0, temperature of 25 ℃and time of 30 min. Then, the obtained calcium-magnesium residue was washed three times with a liquid-solid ratio of 1∶1, and 5 min for each time. As a result, products of calcium carbonate and magnesium carbonate can be obtained. It is concluded that this process, being simple and stable, can be adopted to effectively remove impurities of calcium and magnesium from leaching solution of lepidolite.

研究了从某锂云母矿焙烧-水浸所得浸出液中除去钙、镁杂质的工艺,考察了沉淀剂碳酸钠用量、溶液pH值、反应时间和温度及洗涤条件对去除效果的影响。结果表明,在沉淀剂碳酸钠用量2.21 mol/L、溶液pH=8.0、反应温度25 ℃、反应时间30 min条件下,钙去除率达99.9%、镁除去率达93.1%;所得钙镁渣按液固比1∶1洗涤3次、每次5 min,得到碳酸钙、碳酸镁产品。该工艺方法简单、稳定,能有效去除锂云母矿浸出液中钙、镁杂质。

A technique process to remove impurities of calcium and magnesium from the leaching solution obtained after roasting plus leaching process of a sort of lepidolite was studied, and the effects of several factors on washing effect, including amount of sodium carbonate, solution pH, time and temperature of reaction and washing conditions, were all investigated. The results show that removal rates of calcium and magnesium can reach 99.9% and 93.1%, respectively, by adding sodium carbonate as precipitant at an amount of 2.21 mol/L, with pH of solution at 8.0, temperature of 25 ℃and time of 30 min. Then, the obtained calcium-magnesium residue was washed three times with a liquid-solid ratio of 1∶1, and 5 min for each time. As a result, products of calcium carbonate and magnesium carbonate can be obtained. It is concluded that this process, being simple and stable, can be adopted to effectively remove impurities of calcium and magnesium from leaching solution of lepidolite.
