The mining and processing of tantalite ore is a complex and challenging task, as it requires specialized equipment and expertise to extract the metal from the ore.
Tantalite is challenging to process and is therefore not extensively mined despite the rising demand for it as it. Processing Tantalite. Tantalite appears in granites and other hard rock deposits like carbonites and pegmatites that contain extensive rare-earth elements. Most tantalite mines are open pit, though there are some underground mines.

The coltan ore (short for columbite-tantalite and known industrially as tantalite). In Africa, Nigeria is rich in coltan/columbite resources. Columbite deposits occur in Plateau, Kogi, Kano, Nasarawa, Kaduna, and Bauchi states, mainly in the placer deposits of cassiterite. In Africa, miners must upgrade coltan ore to a saleable grade (like 50-60% …
Columbite has the same composition and crystal symmetry (orthorombic) as tantalite. In fact, the two are often grouped together as a semi-singular mineral series called columbite-tantalite or coltan in many mineral guides. However, tantalite has a much greater specific gravity than columbite, more than 8.0 compared to columbite's 5.2.
Pilgan Plant. Our 2 million tonne per annum (Mtpa) mining and processing operation produces approximately 360,000 to 380,000 tpa of spodumene concentrate.
