A combined technology, Magnetic-Gravity Separation, has been researched for a fine low-grade RE-Nb-Ta ore. As feeding ore containing 0.032%of (Ta+Nb)2O5 and 0.092%of REO, a concentrate containing 3.444%of (Ta+Nb)2O5 and 12.851%of REO with recovery of 44.13%and 57.27%can be obtained. The grade and recovery of RE-Nb-Ta concentrate was improved significantly by the technology.
