Recent practices in mine tailings' recycling and reuse
Indeed, the historical tailings cumulated in the dams and fresh tailings generated from mineral processing plants can be evaluated as raw material for sustainable development and circular economy. Hence, the harmful impact of tailings can be eliminated while using them as potential source in different industrial sectors.

It is a process of separating copper minerals from rocks, through the medium of water and air bubbles to produce concentrate liquid. The process of separating water from the concentrate liquid produces the final product in the form of concentrated sand. The separated water is then used again for activities in the processing plant.
