(EN) The invention relates to a recovery method for removing fluorine from a nickel-cobalt-manganese solution. The method comprises the following steps of: carrying out acid leaching and impurity removal on battery powder to obtain a fluorine-containing nickel-cobalt-manganese solution; mixing the obtained fluorine-containing nickel-cobalt-manganese solution with a fluorine removal agent to obtain a mixed slurry; adjusting the pH value of the obtained mixed slurry to 2-5, and performing filtering to obtain a first-stage defluorination filtrate and a first-stage fluorine-containing filter residue; washing the first-stage fluorine-containing filter residue, adding the washed first-stage fluorine-containing filter residue into alkali liquor, performing heating and stirring, and conducting filtering to obtain fluorine-containing filtrate and nickel-cobalt-manganese-containing filter residue. The method disclosed by the embodiment of the invention has a good fluorine removal effect in the front-section nickel-cobalt-manganese solution, meanwhile, other impurities are not introduced, the obtained fluorine-containing filter residue can meet the requirements of industrial cryolite products after being purified, and the method has great economic benefits.
(ZH) 本发明涉及一种镍钴锰溶液中除氟的回收方法，包括以下步骤：将电池粉料进行酸浸、除杂后，得到含氟的镍钴锰溶液；将所得含氟的镍钴锰溶液与除氟剂混合，得到混合浆料；将所得混合浆料调节pH至2‑5，经过滤得到一段除氟滤液和一段含氟滤渣；将一段含氟滤渣洗涤后加入碱液中，加热搅拌，经过滤得到含氟滤液和含镍钴锰滤渣。本发明实施例的方法在前段镍钴锰溶液中具有较好的除氟效果，同时不引入其它杂质，并且得到的含氟滤渣进行提纯处理后可以达到工业冰晶石产品要求，具有较大的经济效益。
