Mineral Resource of the Month: Tantalum
Tantalum is almost always found with niobium. Although it is a metal, tantalum is not found in metallic form in nature. It is found in tantalum-bearing oxide minerals such as euxenite, microlite, polycrase, tantalite, columbite and wodginite. Tantalum minerals contain 12 to 84 percent tantalum pentoxide; however, tantalum ores are low …
