Frequently Asked Questions

What does electrowinning mean?

Definition of electrowinning. : the recovery especially of metals from solutions by electrolysis.

What is electrowinning in electroplating?

Electrowinning. In electrorefining, the anodes consist of unrefined impure metal, and as the current passes through the acidic electrolyte the anodes are corroded into the solution so that the electroplating process deposits refined pure metal onto the cathodes.

What is the difference between electrowinning and electrolysis?

As nouns the difference between electrowinning and electrolysis is that electrowinning is the electrodeposition of metals from their ores that have been put in solution or liquefied while electrolysis is (chemistry) the chemical change produced by passing an electric current through a conducting solution or a molten salt.

What is electrowinning of copper?

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
