The Role of Mine and Industrial Wastes in the Growing Demand of Mineral Resources

The increased demand from modern societies, growth of technological applications and Green Energies has increased the global thirst for mineral resources across many commodities (e.g., Au, Li, In, Co, REE, PGEs). Indeed, several Critical Raw Materials (CRM) reports have been published by respected national organizations (e.g., European Commission, U.S. Geological Survey, British Geological Survey) documenting this. Independently, these recognize the opportunity for considering valorization of mine waste materials and industrial by-products as ‘green’ alternatives to support part of the future needs of these strategic resources instead of purely exploring for greenfield sites. Hence, this special issue invites contributions that bring new perspectives on revalorization of CRM hosted in mine and industrial wastes. This includes, but is not limited to topics such as: a) characterization of the mineralogical and biogeochemical processes governing the appearance and evolution of CRM within mine and industrial residues; b) novel geometallurgical applications to reprocess mine and industrial residues and improve the exploitation perspectives of the hosted CRM resources; and c) environmental studies related to waste reprocessing (e.g., acid mine drainage generation potential, definition of geoenvironmental units, safe disposition of the final residues after tailing reprocessing). Additionally, we welcome contributions on d) dealing with the potential reuse (new use or application) and recycling (converts the mine wastes into a new product or application) of mine and industrial wastes as part of the solution for sustainable mining and waste disposal.
