碳酸锶废渣酸浸液的钙锶分离研究

Study on Separation of Calcium and Strontium in Acid Leaching Solution of Strontium Carbonate Residue

对碳酸锶废渣酸浸液进行蒸发、结晶、过滤,得到初步纯化的氯化锶,再对其进行水溶、除钙等处理,以达到精制氯化锶的效果。在得到高纯氯化锶溶液的同时,回收了氯化钙。该方法通过简单的操作实现了碳酸锶废渣酸浸液的钙锶分离。

Acid leaching solution of strontium carbonate residue was evaporated and crystallized. After fil- tration,primary purified SrCl2 was obtained, which was purified by dissolving and removing calcium. And then CaCl2 was recovered while high-purity solution of SrCl2 was gained, the Separation of SrCl2 and CaCl2 in acid leaching solution of SrCO3 residue was achieved by the method mentioned in this paper.
