Method for removing ferrous ions from neodymium iron boron waste recovery liquid

Номер: CN116004988A
Автор: LI XUEWEI, WAN YINHUA, ZHOU XIAOWEN, XU QIAN, LIU YUCHENG
Принадлежит:

The invention relates to a method for removing ferrous ions from neodymium iron boron waste recovery liquid, which comprises the following steps: mixing the neodymium iron boron waste recovery liquid with calcium magnesium carbonate for reaction, standing and then carrying out solid-liquid separation to obtain a liquid phase which is an iron removal solution and a solid phase which is filter residues containing ferric oxide hydroxide and calcium magnesium carbonate. According to the method, an oxidizing agent and a pH adjusting agent do not need to be additionally added, calcium magnesium carbonate is adopted as a removing agent, efficient separation of neodymium and iron is achieved, the removal rate of ferrous ions is high, the loss rate of neodymium ions is low, the technological process is short, operation is easy, and the method is suitable for large-scale industrial production.
