How to Make Filtered Tailings Feasible | E & MJ
Some iron-ore mines have 50%-55% metals content in their tailings, which is amazing really. And there are copper operations with 0.5% of copper in their tailings which is higher than what's in the ground. It's just a question of dredging the material and floating the metal or using magnetic separation.".

Tailings
Pollution. In mining, tailings or tails are the materials left over after the process of separating the valuable fraction from the uneconomic fraction ( gangue) of an ore. Tailings are different from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.

How to reshape the future of tailings?
Mining involves processing of mined ore to capture valuable minerals, which in turn produces large volumes of tailings. The annual global tailings production is currently estimated to be at the range of 10-12 billion tons/annum and increasing. Therefore, it's important to reshape tailings management and accelerate the positive change.
