| Abstract: | The recovery of copper from the acid waste water containing copper in the copper was studied. After the study of sodium sulfide and cave pit water contact reaction 15min reaction, ORP control in 150~180mv, underground water pit copper recovery rate is greater than 95%, the best metal recycling economic benefits, at the same time after solution treatment to achieve national I class water discharge standard. The method is beneficial to reduce the cost of wastewater treatment, improve the comprehensive utilization of copper resources, and has good economic and social benefits. |
