摘要
针对离子交换法生产 APT(仲钨酸铵 )现行工艺中结晶母液必须另设辅助流程处理的缺点 ,提出了一种新的工艺流程 ,即用纳滤法从结晶母液中选择性地脱除氯离子 ,避免了氯的积累 。
A new method for recovering tungsten from the crystallized barren liquor isstudied.In this process,the chloride ion can be removed selectively from the barren liquor by using nanofiltration method.The feasibility of commercial application of this process is discussed.
