Abstract: Impact of precipitating on removing harmful metal ion in the acid mine wastewater with pH neutralizer and sulfide was studied. The possible way of retrieving heavy metal ion in wastewater was probed. The techniques for lime carbonate to reject iron for hydrogen sulfide to precipitate copper and for zinc-lime cream neutralization flocculation to treat, mine acid wastewater were chosen. The final water quality may reach national effluent standard; the copper content was 32% in the sulfide slag.

Abstract: An historic underground copper mine in Wyoming is discharging neutral but copper-laden water into a pristine creek. The EPA-deferred site qualifies for reclamation by the Wyoming Abandoned Mine Land (AML) program. The cleanup goal is to restore the discharge so that the creek can eventually support a trout fishery. Hydrological and geochemical investigations underground have suggested two sources of mine water: one clean and the other containing copper. Results of bench- and pilot-scale tests support the viability of using low-cost passive treatment techniques to reduce copper concentrations in the near-freezing mine discharge.
