Keeping Up with Demand: Copper Tailing Reprocessing
Copper is a key resource in modern industry and society. However, copper is finite like all natural resources, and increasing demand for this material depletes global copper reserves. Recovering copper is a crucial strategy to keep up with demand. One approach is to reprocess mining tailings to extract the vital copper resources within.

Review of closed water loops with ore sorting and tailings valorisation
Tailings storage is the largest water sink in most mines (Gunson et al., 2012) with over 50% of water losses coming from the water trapped in the pores in the tailings (Donoso et al., 2013).Tailings disposal thus needs close attention in the mine water management (Gunson et al., 2012).Tailings and mine water issues should be considered simultaneously, not separately, …
