| Abstract: | Low and medium-grade niobium oxide ore of the Zhudong mining area, Baiyan Obe mine, is of great value to us in our comprehensive covery of Baiyan Obo mine's mineral resources. The authors discuss the characteristics and separation properties of main niobium minerals, concluding that low intensity magnetic separation-high intensity magnetic separation is an effective way to prcliminarily concentrate niobium. The niobium-enriched magnetic middling obtained by high intensity magnetic separation is separated by f]otatation, obtaining a niobium and rare-earth-enriched iron concentrate or higher grade niobium-enriched iron concentrate. The authors describe some operational conditions and reagents for recovering niobium from the niobiumenriched magnetic middling by flotation. |
