No. You misunderstood the announcement.
And from the paper (if you have read it) and the announcement, TLG provided 99.7% purity micrographite for the research purpose, the preparation of graphene oxide was done by the researchers. The benefit was from the micrographite the graphite companies usually overlooked.
"This conductive graphite bearing ore was further processed by Talga Advanced Materials GmbH to give Cg of 99.7% by graphite beneficiation technique. This high-grade micrographite utilised as starting materials for research purpose to produce graphene oxide (GO) and reduced graphene oxide (rGO) by modified Hummers. Sulfuric acid (H2SO4, 98%), potassium permanganate (KMnO4, 99.9%), hydrogen peroxide (H2O2, 30%), hydrochloric acid (HCl, 37%) disodium phosphate (Na2HPO4, 99%), sodium nitrate (NaNO3), ........... "
