Technical and Environmental Considerations for Valorisation of Mine Tailings. Abstract This thesis investigates the valorisation of copper mine tailings, focusing on their potential as a valuable secondary resource. This study explores the recovery of residual minerals and the transformation of residual waste into commercially viable products, such as cement, ceramics and geopolymers. Various case studies are analysed, evaluating the technical and environmental feasibility of different reprocessing methodologies. Chapter 1 introduces the problem of tailings management and the importance of developing efficient strategies for resource recovery. In Chapter 2, the scope of copper tailings valorisation is defined, with a detailed review of the available literature on the subject, highlighting gaps and opportunities for innovation.
