Generally, metals are extracted from ores collected from hard rock mines. Recent advancement in mineral extraction technologies and declining ore grades in primary deposits have led to the idea of reprocessing of mine tailings as the potential secondary source of some of the critical minerals [15], [16], [17], [14].

A standard method of reprocessing involves dragging tailings from an existing dam back to the concentrator and using required mineral processing solutions to liberate the valuable metals. The discarded tailings are then dewatered and dry stacked, and the water recycled within the plant or properly disposed back to nature.

To increase resource efficiency, mining residuesespecially tailingshave come into the focus of research, companies, and politics. Tailings still contain varying amounts of unextracted elements of value and minerals that were not of economic interest during production. As for primary mineral deposits, only a small share of tailings offers the possibility for an economic reprocessing. To ...

10,180,000,000. 8,850,000,000. Tailings are what is left over after mills separate the metal from the mined rock. The processed material "tailings" comes from the "tail" end of a mining mill and comprise fine particles mixed with water forming a slurry. Mining companies will store this waste in dams or ponds.
