  • Copper electrowinning: theoretical and practical design

    The electrowinning of copper ions derived from leaching, or solvent extraction is a significant contributor to the global copper commodity supply. The process of electrolysis for copper was first developed in the late 19th century and despite numerous advancements in technology the principles and basic equipment remain the same.

  • Electrowinning an overview ScienceDirect Topics

    Typical of electrowinning from aqueous solutions is copper electrowinning. The electrolyte entering the cells contains 25–60 g l -1 of copper, 50–180 g l -1 of sulfuric acid, and 5–10 g l -1 of iron salts (Habashi, 1998). It is produced by leaching of copper ores, with solution purification by solvent extraction.

  • Electrowinning

    Electrowinning is defined as the cathodic deposition of metal, in this example copper, from a copper bearing solution by the passage of an electric current current using an insoluble anode. For copper the electrowinning reaction reaction is: CuSO4 + H2O ⇒ Cu + ½O2 + H2SO4 The overall reaction is the combination of two electrochemical half reactions. The cathodic reaction is: Cu++ + 2e
