Talga Resources Ltd. has completed the commissioning of the phase-two graphene pilot plant in Germany.

The ASX-listed company said Sept. 27 that new recovery and upgrading circuits have been installed and successfully tested, and high-quality grapheme output has been confirmed.

Currently, about 76% of the graphitic carbon is converted to graphene, with the remaining carbon being used in Talga's building sector products.

Talga said the final configuration will be subject to process optimization during the pre-feasibility study.
