In Queensland, mapping shows plentiful cobalt at mine sites in the state’s north west, while on the west coast of Tasmania state, cobalt can be found mixed in pyrite in mine waste, which can oxidize over time into acid, Parbhaker-Fox said.Recovery of these metals will offer a chance to stop the pyrite oxidizing.“We see mine waste as a huge opportunity,” said Helen Degeling, project acquisition manager at developer Cobalt Blue.Cobalt Blue’s processing plans target pyrite, which was previously overlooked because it was difficult to process, but with cobalt in demand for battery materials, now has value.“Turning it into a useful product has not only economic value but strong environmental positives as well,” Degeling said.

COB is being recognized in the mining media for a diverse approach to cobalt mining extraction to enhance their mining and processing capabilities IMO.
