Abstract:Reaction mechanism, processing and application of controlling cathodic potential electrowinning were studied. When the new technology was used in electrowinning processing,hydrogen and arsine were not evolved. Compared with various parameters of disconnected and continuous electrowinning, the cathodic potential electrowinning have many advantages, such as high current efficiency, high work efficiency, low energy consumption and strong impurity removal ability. Industrial application experiments indicate that the new technology can be controlled easily and operated simply and safely, and has extensive economic and social values. 

 

Key words: copper electrolyte; purify; cathodic potential; arsenic removal
