2017-2-13  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. The primary feedstock is ore mined at the Volta Grande Mine operations.
