Research Progress on Solvent Extraction Technology in Niobium-Tantalum Separation
摘要
Abstract
Niobium and tantalum are strategic rare metals,and their efficient separation and purification are crucial for the sustainable utilization of resources.The resource characteristics and industrial demand of niobium and tantalum are summarized,and the research progress of solvent extraction method in niobium and tantalum separation is focused on.The formation mechanism of niobium-tantalum fluoride complexes and their coordination behavior with extractants are discussed.The extraction performance of ketones,esters,amines,crown ethers,organic phosphonates,and novel functionalized ionic liquid extractants is summarized,and current challenges and development trends are outlined.关键词
