| 摘 要： | 研究了利用毒重石为原料，添加ＭＯ除杂剂，盐酸浸出制取氯化钡的工艺。当ＭＯ用量为１０ｋｇ／ｔ，盐酸用量为４１４ｋｇ／ｔ，液固比为４时，钡的浸出率达９８．４１％。浸液直接浓缩结晶，制备的氯化钡产品质量达到了ＧＢ１６１７—８９─级品标准。 |
| 关 键 词： | 毒重石，氯化钡，浸出 |

| Abstract: | The process. in which witherite is leached by hydrochloric acid with MO decontaminant to prepared barium chloride, is studied. When the usage of MO and hydrohloric acid, and the liquid-to-solid ratio are 10kg/t, 414kg/t and 4 respectively,the leaching rate of barium is 98. 41%.The product quality of barium chloride prepared by leaching liquid thickening and crystalling reaches the first grade standard of GB1617-89. |
