(2022), who present the main metallic mineral resources (bauxite, lead and zinc), abundant non-metallic mineral resources (industrial minerals and construction materials) and secondary mineral resources (in particular, aluminous red mud and Pb and Zn operational and abandoned mine tailings, bottom and fly ash from thermal power plants, slag from steel production, and marlstone and limestone from hanging walls of coal deposits) and waste rock for aggregate production. (2022) have produced a basic characterization of selected tailings of active and abandoned mines in Serbia (Bor, porphyry Cu/Au; Krivelj, porphyry Cu/Au; Blagodat, hydrothermal Pb-Zn; Lece, epithermal Au; Rudnik, hydrothermal/ skarn Pb-Zn) and North Macedonia (Sasa, Pb-Zn; Probištip, PbZn; Bučim, porphyry Cu; Lojane, fault-bound vein-type low-temperature As, Sb, Cr at the contact of rhyolite and serpentinite). Social acceptance of future mining operations no longer depends solely on the economic or strategic value of the discovered resources, but also the transparency and community inclusion, wider-society benefits, and sustainability of the presented projects.
