The processing of tantalite-columbite ore is complex due to its low content and sophisticated composition. Usually, the enrichment flow sheet of tantalite-columbite covers rough concentration and fine selection. And for different tantalite-columbite mines, the specific flow sheet can be different.
For alluvial tantalite-columbite, the minerals are basically liberated from the gangue with the useful mineral density over 4g/cm3 and sometimes the minerals are magnetic. Gravity separation is mainly used as rough separation while combination of magnetic separation-gravity serration and magnetic separation-electric separation and floatation separation is adopted for the fine selection of rough concentrate from gravity separation.
