Tantalum from the Wodgina mine is sourced as a co-product of lithium much like the tantalum from the Greenbushes mine. Any tantalum produced at Wodgina is processed through GAM owned tantalum recovery circuits and sent to our Greenbushes operation for secondary processing where we produce on-specification, saleable tantalum products.

The measurements indicated that an extremely thin layer of tantalum oxide—less than one nanometer thick—remains confined directly beneath the magnesium/tantalum interface without disrupting ...

The results showed that the electrode reduction process of tantalum ion in NaCl-KCl molten salt at 1023 K is a two-step reaction Ta (V)→Ta (II)→Ta, and the reaction Ta (V)→Ta (II) was reversible and controlled by diffusion. The nucleation mode of tantalum ion was determined to be instantaneous nucleation by chronoamperometry.
