How to Make Filtered Tailings Feasible E MJ

2020-4-8 Our studies indicate that metals obtained from reprocessed tailings can be up to three times cheaper than virgin ore. 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.
