Abstract
Copper electrorefining is a key part of copper metallurgical processes. The electrolyte is usually purified to prevent the accumulation of impurities and contamination of the cathode. Cyclone electrowinning is a widely applied purification method, but black copper mud that contains arsenic is produced after the process and endangers the environment. With the addition of effective chelators, controllable electroplating can be achieved. In order to investigate their role in electrodeposition, a variety of chelators were selected and applied in this study. LSV, XRD, and SEM were used to characterize Cu-As alloys produced from each test. The effects of chelators on the number and shifting of phase transition zones during the electrodeposition were analyzed.
