2. Bring the solution in contact with S02 gas in reaction towers. The reaction involved will reduce the ferric iron to ferrous iron and generate sulphuric acid. The reaction involved is as follows: /3:328/ Fe2(S04)3 + S02 + 2H20 3. Pass the solution over cement copper. All but a trace of the ferric iron is removed; however, no sulphuric acid is generated.

Electrowinning - Wikipedia

Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal. Both processes use electroplating on a large scale and are important techniques for the economical and straightforward purification of non-ferrous metals. The resulting metals are said to be electrowon. In electrowinning
