A Sustainable Approach to Transforming Mining Waste …
Mineral waste can be defined as a material leftover from exploration, mining and quarrying operation that cannot find a productive use. It is the high-volume material that originates from the excavation and physical and chemical processing of a wide range of metalliferous and non-metalliferous minerals by opencast and deep shaft methods [].The …
Recent practices in mine tailings' recycling and reuse
Indeed, the historical tailings cumulated in the dams and fresh tailings generated from mineral processing plants can be evaluated as raw material for sustainable development and circular economy. Hence, the harmful impact of tailings can be eliminated while using them as potential source in different industrial sectors.
