pare high pure copper, crud anodes are dissolved electro-chemically and then deposited at the cathode. During the electrorening process, elements or compounds, which are either nobler than copper or insoluble in the sulfuric acid, are deposited at the bottom of the electrorening cell to form copper anode slime. The composition of copper anode ...
Careful monitoring and control of all aspects of the process are necessary to ensure the desired film formation and to control the quantity of anode sludge created.
