The experimental study on magnetic field intensity,grinding fineness,rough concentrate cleaning and com-prehensive recovery of non-metallic minerals was conducted on a sodium-albitization granite-type tantalum-niobium ore in Jiangxi Province.The results showed that through the magnetic separation process,the original mineral yield was 0.039%,Ta2O5 grade was 14.39%,Nb2O5 grade was 35.48%,and the original mineral yield was 7.88%,Li2O grade was 2.25%,Rb2O grade was 0.72%.The yield of quartz feldspar concentrate was 78.09%,This provides a reference for the selection of subsequent mining production or similar tantalum niobium ore beneficiation processes.
