Characterization and identification of Au pathfinder minerals from an artisanal mine site using X-ray diffraction [PDF]

Journal of Materials Science, 56(12), 7659-7669 (2021), 2021
Gold-associated pathfinder minerals have been investigated by identifying host minerals of Au for samples collected from an artisanal mining site near a potential gold mine (Kubi Gold Project) in Dunkwa-On-Offin in the central region of Ghana. We find that for each composition of Au powder (impure) and the residual black hematite/magnetite sand that ...
