The alkaline extraction of copper from galvanic dross

On the theoretical side, we investigate the possibility of chemical extraction of copper from galvanic dross. We study the processes of extracting copper from the model mixtures and original dross of ammoniac solution. Furthermore, we consider the electroextraction of copper from lixiviation solutions. An emphasis is laid on determining the technological conditions of extracting copper from galvanic waste production. Finally, we propose the fundamental technological scheme of reprocessing galvanic dross containing copper with the calculation of material balance.
