Abstract:
Chelating electroplating sludge contains high grade of toxic metals or heavy metals, so this
sludge should be treated and recovered of valuable metals from it. This paper mainly studied on the
recovery process of Copper, Nickel and Zinc process from sulfuric acid leaching solution of roasted
chelating electroplated sludge. It provided an effective technique for recovery of valuable metals from
acid leaching solution. The efficiency of the process had been measured with the metal recovery rate.
Experimental results showed that recovery rate of Copper and Nickel can respectively achieve at
99.30% and 97.00% from acid leaching solution after removal iron with zinc powder used reducing
agent. The process has simple operation and high recovery rate. It can solve the environmental
pollution problem of electroplating sludge and valuable metals can be recovered from which. It could
bring better economic and environmental benefits to the enterprise.
