Tantalum concentrate is the feed source used by the processors to produce tantalum capacitor powders and metallurgical products. The concentrate is also used to produce pure tantalum pentoxide (Ta2O5) primarily utilized in the production of optical glass and lithium niobate.
Tantalite is also very close to tapiolite. Those minerals have same chemical composition, but different crystal symmetry orthorhombic for tantalite and tetragonal for tapiolite.
Tantalite is black to brown in both color and streak. Manganese-rich tantalite can be brown and translucent.
