Bioleaching Of Coppercontaining Electroplating Sludge

May 01, 2021 Conclusions. Copper-Containing Electroplating Sludges is classified as hazardous waste. However, it can also be considered as recyclable resource as it contains a lot of valuable metals. Results show that bioleaching, using mixed microbes, has a much better performance (21.1% higher) than sulfuric acid leaching.
