摘要
在电解槽中连续电还原废钕铁硼分解液,电还原完全后分解液进萃取槽进行萃取分离除铁,连续工业生产,稀土回收率:98.13%。回收的稀土料液可用于P507-HCl体系稀土分离。
Waste neodymium, iron and boron decomposition liquor is electro-reduced continuously in electro-bath. After complete electro-reduction, the decomposition liquor is extracted for removing iron in the extraction tank. The recovery rate of rare earth is 98.13 %. The recovered rare earth feed solution can be applied to P507-HCl system.
