Improper management of dumped tailings not only causes a potential waste of resources but also poses a direct threat to the lives of local residents. A dual-chamber microbial fuel cell (MFC) combining with the bioleaching technique was used in the study to extract Cu from the secondary mine tailings at a fed-batch scale.
The bench-scale kinetics test achieved 16.3% Cu recovery and 28.5% MoS 2 recovery in 15 min, while the StackCell SC-50 achieved an average of 15.6% Cu recovery and 16.2% MoS 2 recovery in 1 min. Thus, the StackCell SC-50 achieved roughly the same copper recovery as the conventional bench-scale cell with only 1/15th (7%) of the residence time.
The physical-chemical strategies of conventional technologies, such as constructed barriers were implemented to prevent the further spreading of tailings, but are limited by their high costs (approximately 100–500 $/ton) (Cristaldi et al., 2017).Phytoremediation are also limited because the acidification conditions of tailings may inhibit the survival of native plants (Zhou …

The product of gravity-induced separation is the mature fine tailings, which are characterized by a small proportion of fine particles (30 wt%) suspended in water (83 v.%) (Vedoy and Soares, 2015). In contrast to the fast gravity-induced separation, fine particles will remain suspended for decades in mature fine tailings without human intervention.
