中文摘要:

      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.

英文摘要:

      Acid leaching solution of strontium carbonate residue was evaporated and crystallized.After filtration,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.
