无机盐生产中锶钙分离

Separation of strontium and calcium in production of inorganic chemicals

锶钙分离对于生产高纯锶盐及利用含有大量钙的单一锶矿、伴生锶矿或卤水锶矿具有重要意义。基于锶钙的一些基本性质,介绍并评价了沉淀法、溶剂萃取法、离子交换法等分离方法的研究现状和在无机盐工业中应用的情况。最后对上述几种主要分离方法的优缺点进行了比较,并对卤水锶矿中锶的利用进行了展望。

Separation of strontium and calcium is very important in the production of high - purity strontium chemicals, and in the industrial application of single strontium ore, associated strontium ore or brine strontium ore with high content of calcium. The present of research and industrial application situation of separation methods for the two elements by precipitation, solvent extraction and ion exchange method etc. have been reviewed and remarked on the basis of some fundamental properties of strontium and calcium. Lastly, the advantages and disadvantages of these separation methods were compared and the prospect of the use of strontium in strontium brine was also expected.
