Electrowinning Copper Chemistry Tutorial - AUS-e-TUTE

Electrowinning Copper Key Concepts. Electrowinning refers to the process of using electrolysis to extract a metallic element from the compounds in its ore. Copper occurs on Earth both as native copper (the uncombined element, Cu), and in ores (copper compounds, or mixtures of compounds, from which copper metal can be extracted profitably).

Electrowinning - Metallurgist Mineral Processing Engineer

Nov 17, 2020  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.
