Ultra fast ultrasound-assisted decopperization from copper anode slime
Ultrasonics Sonochemistry, 2017 An ultra fast decopperization method from the anode slime has been developed based on the ultrasound-assisted leaching. The effects of parameters such as ultrasound power, leaching time, sulfuric acid concentration and liquid/solid ratio were investigated. Under optimum conditions, the concentration of Cu in residue was only 2.64%.
