【Abstract】 New technological process to extract copper powder and nickel sulfate from electroplating sludge was reported in this paper, and the economic barometer of technology procedures was examined in test. The grade of obtained copper powder was higher than 90%, with the coefficient of copper recovery more than 95%, and the rate of nickel recovery exceeded 80%. Besides, the quality of the obtained nickel sulfate reached industrial first grade. The solidification residue could be used as common building materials and the wastewater of the technical process could be discharged up to the standard.更多还原
