天青石矿制取高纯度碳酸锶的研究

on Preparation Method of Pure Strontium Carbonate by Celestine

将天青石矿（SrSO_4）与碳酸氢铵复分解，生成粗碳酸锶，加入盐酸溶解，再加入硫酸除钡，经控制试验条件除铁后，用碱除去钙、镁等杂质，可制成高纯度的碳酸锶。

Celestine and ammonium were prepared raw strontium carbonate by metathetical reaction. Add chlorhydric acid tosoluation, then, add sulfuric acid without barium and iron by the controlled experimental condition, Abating Calcium,magnexuim and impurity with base, in this way, the pure stronrium carbonate will be got.
