制法一：碳化法在硫化钡溶液(制备参见硫化钡)中通^二氧化碳气进行碳化，得到碳酸钡浆液经脱硫洗涤、真空过滤、300℃下干燥、粉碎，制得碳酸钡成品。其反应式如下：
BaS+CO2+H2O→BaCO3↓+H2S↑
复分解法由硫化钡与碳酸铵进行复分解反应，再经洗涤、过滤、干燥等，即得碳酸铋成品。其反应式如下：
BaS+(NH4)2CO3→BaCO3↓+(NH4)2S
毒霞石转化法将毒重石矿粉与铵盐反应生成可溶性钡盐，同时将碳酸铵回收使用，可溶性钡盐加入碳酸铵沉淀出精制碳酸钡，经过滤、干燥，制得碳酸钡成品。得到的母液，经回收循环使用。

制法二：碳化法。反应方程式：
BaS+CO2→BaCO3↓+H2S↑
操作方法：将1L含硫化钡180g/L的水溶液与二氧化碳在70℃反应，生成沉淀碳酸钡。沉淀用10ml 25%的氨水混合，在60℃脱硫20min。过滤、干燥后得沉淀碳酸钡，产品中含硫0.46%。
复分解法。反应方程式：
BaCl2+NH4HCO3+NH4OH→BaCO3↓+2NH4Cl+H2O
操作方法：在30℃, 将23.6L含碳酸氢铵56.1g/L的水溶液与1.36L氨水在50L釜中混合，然后在50℃、在2h内滴加21.6L 200.3g/L的氯化钡溶液，在40℃搅拌30min。过滤，在140℃干燥，粉碎，得碳酸钡平均粒径d为0.8μm,纯度99.8%。
