recovery of copper from mine warter

Recovery of copper from Chilean mine waste waters -

2016-7-31  Ion exchange is demonstrated to be a straightforward, reliable, and relatively low-capital technology for the recovery of copper from mildly acidic mining waste streams, and can be profitably operated to create additional revenue for mine sites. It readily handles fluctuations in feed concentrations and flowrates, and can be optimised to consistently produce a low-volume, high-purity, high-concentration product stream from which LME Grade A copper cathode or other value-added copper

Recovery of Copper from Acid Mine Drainage by an ...

An integrated sulfate reducing process was used to treat Acid Mine Drainage with high concentrations of Cu2+, Fe and SO42-. The water treatment system integrated a sulfidogenic UASB bioreactor with a precipitation reactor which was used to recover copper. Sodium lactate was used as energy source. The effective volume of the UASB reactor was 2 L and the hydraulic retention time was 12.57h.

Experimental Comparison of Processes for Recovery of ...

2018-1-2  The results of copper recovery from the dump water of a copper and zinc deposit with an NaHS consumption of 95-135% of the corresponding stoichiometric value have shown (Fig.1) that it is not possible to fully separate copper from zinc. With a copper recovery rate of over 65% more than 5.49% of zinc is precipitated. Because there is several times more zinc than copper in the mine water the zinc weight content in the precipitate is on a par with the copper weight content. Increase in consumption to over 115% leads to the precipitation of Fe (II) and zinc in quantities exceeding that of copper.
