中国碳酸锶工业生产现状与进展

阐述了碳酸锶的用途，介绍了中国锶资源情况及碳酸锶的主要制备方法和技术进展。作为一种重要的化工原料，碳酸锶主要用于制备彩色显像管玻壳和磁性材料。目前，由天青石制备碳酸锶的方法主要有炭还原法和复分解法。中国天青石资源十分丰富，但矿石品位低、杂质含量高，需经选矿除杂后才能作为生产碳酸锶的原料。因此，研究开发有效的天青石选矿技术，以及使用选矿获得的天青石精矿制备碳酸锶的新工艺是未来中国碳酸锶工业的主要发展方向。

Progress and present status of strontinum carbonate industry in China

The use of strontinum carbonate and strontinum resourses in China are described. Several main preparation methods of strontium carbonate and their technology development are also introduced. As an important chemical raw material, strontinum carbonate is mainly used as an additive in the production of color television tubes and a constituent of ferrite magnets. The current preperation methods of strontinum carbonate from celesite are carbon reduction method and double decomposition method. China is rich in celesite resourses, but most of them are low - grade and high impurity ores. Beneficiation is needed to use these ores to prepare strontinum carbonate. In the future, The main development direction of strontinum carbonate industry in China is to develop effective mineral separation technologies of celesite and using celesite concentrate to prepare strontinum carbonate.
