Contaminated acid is a common waste acid in nonferrous metals smelting,which is characterized by complicated component,high acidity and hard to deal with. Contaminated acid is also the main source of the acid heavy metal ion wastewater in smelting plant. The traditional treatment process produced a large number of hazardous waste and cost a lot. Cyclone electrowinning technology with wide application and high selectivity attracted more and more attention. In this paper,cyclone electrowinning technology was ...
