Tantalum is a specialty metal that improves conductivity and is highly resistant to heat and corrosion. AMG has a capacity to produce 300,000 pounds of high purity tantalum oxides (Ta2O5) in concentrates annually. Tanatalum oxides are used as a material in capacitors used in electronics such as computers, smart phones and video games.

AMG also produces Niobium Oxides from the same ore body as tantalum. Niobium is used mostly in alloys, such as in specialty steel and titanium.
