How to beneficiate the tantalum niobium ore in Nigeria?
Most of the tantalum and niobium mines in Nigeria are sand mines, with large mud content and strong clay viscosity, which is easy to bond into agglomerates. The sand mines contain not only niobium ore, tantalum ore, but also cassiterite, and the ore grade is mostly at 1% Above, the selectivity is very strong.
The Future of Tantalum and Niobium - Mining Technology
Indeed, until the discovery of the world's pyrochlore deposits in the 1950s, niobium was a by-product of tantalum mining, with increasing demand ensuring that it was highly valued and highly priced. All of the world's main tantalite mines are hosted in pegmatite ore bodies, including Wodgina, Greenbushes, Marropino and Bernic Lake in Canada.
