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. We produce five grades of
tantalum concentrate at our Greenbushes plant in Western
Australia. The primary feedstock is ore mined at our Wodgina
operations, while a small amount is sourced from other mines in
