The African Tantalite Mining Industry

Chemically, tantalite is similar to columbite, and the two minerals are often grouped together in mineral guides. However, the specific gravity of tantalite is significantly higher than that of columbite. Tantalite is challenging to process and is therefore not extensively mined despite the rising demand for it as it. Processing Tantalite
