Recycling Copper Mine Tailings. Mine tailings tailings are finely ground rocks and other mineral waste as a result of mineral to the way minerals are processed, tailings can contain concentrations of processing can make mine tailings an environmental concern, so proper transportation and disposal are crucial.
· Mining Waste. The Great Lakes region has long been a productive area for mining various minerals and ores. For over a century, Michigan's Keweenaw Peninsula has been the site of copper mining. This has resulted in approximately 500 million tons of tailings, fine sandlike material left over by the copper extraction process.
· There are various types of mine tailings discharged, including iron, gold, copper, manganese, leadzinc, vanadium, rare earth, and platinum tailings (Abraham and Susan 2017; Galvão et al. 2018; Gandarillas et al. 2019; Yang et al. 2003). Thus, there have been significant interests in studying and developing technically feasible and environmentally acceptable technologies for metal recovery ...
