| Abstract: | The process of recovering rare earth from waste neodymium iron boron is with long process flowsheet and comsums lots of chemical materials.It is very necessarty to research a new process with short flowsheet,less material comsumption and low costs.Test results show that electrical reduction-P507 extraction separation method is feasible to recover rare earth from the waste neodymium iron boron and cost effective. |
