“…The development of an alternative source of raw material, which can be used as a secondary resource and produced from the mining waste of stocked piles, leading progressively to their eventual elimination, in addition to the obvious financial benefits, can have also a positive social impact, since the improvement of the natural environment can be improved, i.e., by minimizing dusting and leaching, but also the overall public opinion for the mining activities can be ameliorated [15]. It is certainly very important that the mining wastes, considered onwards rather than by-products, i.e., as a secondary raw material, can be further used and recycled, e.g., in earthworks and construction sites, in asphalt surfaces, but also as cement or geopolymers constituents, or in ceramic tile manufacturing [16,17].…”
