Research Progress of NdFeB Scrap Resource Utilization and"Dual Carbon"Proposal
NdFeB scrap contains a large number of valuable elements such as rare earth elements,B and Fe.Therefore,NdFeB scrap has a great prospect of resource recovery,which can effectively improve the situation of rare earth resource shortage,environmental pollution,and resource waste.In this paper,the current situation of NdFeB scrap disposal is taken as the initial point.The research progress of traditional recycling technology,new recycling technology,and high-value recycling of NdFeB scrap is discussed in detail,and the advantages and disadvantages of these methods are summarized.In addition,the environmental impact of different recycling pro-cesses of NdFeB scrap and the relationship between different disposal processes and the goal of"Dual Carbon"are reviewed.Finally,given the challenges and development trend of NdFeB scrap resourcization,several poli-cies are proposed for the development of the NdFeB industry.The above research is expected to provide guid-ance and help in the resourceful recovery process of NdFeB scrap and the development of the rare earth industry.
