Tantalite and Columbite Mining Processing Equipment

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 raw tantalite-columbite and microlite, the Tantalum and niobium is usually mixed together ...

Niobium Minerals Production TIC

Columbite, the niobium rich homologue of the mineral columbotantalite, occurs in Brazil, Nigeria, and other countries in central Africa. Unlike pyrochlore, columbite is not processed at or near the minesite into niobium metal products, but is transported to the same processing industries which receive tantalum raw materials. There, the columbite is treated in the same manner as tantalite and ...
