Tailings embankments are part of the legacy left by the intensive mining industry. These vast impoundment storages are associated with some adverse environmental and social impacts creating insecurity to the stakeholders. Mining tailings may also be a source of minerals with high grades. Reprocessing techniques may be used as an alternative solution to recover some metals and to rehabilitate these sites. A sustainable reprocessing project commits to integrated management of threefold dimension objective: economic ...

The reprocessing of tailings is gaining importance both for economic and environmental reasons. In the case of abandoned mining waste disposals, the reprocessing of tailings constitutes an option that can be considered to fit the paradigms of the actual mineral industry challenges: circular economy and sustainability. The present study focuses on the tailings of an old embankment (Cabe?o do Pi?o) of the tungsten Panasqueira mine, in central Portugal. Although Panasqueira mine is still in operation today, it had it...
