In this study, a novel anion exchange membrane (AEM)-based EW process is benchmarked against a process without and with a porous Terylene membrane by comparing the current efficiency, specific energy consumption (SEC), and sulfuric acid generation using an in-house constructed EWThe Effect of Ferric Iron Upon the Current Efficiency and,,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 of iron from sulphate solutions - SINTEF,Electrowinning of iron from sulphate solutions.

Sulfate Solution - an overview | ScienceDirect Topics
For nickel electrowinning from sulfate solutions, sodium sulfate levels are kept high in the plating solution to lower resistivity and raise pH. Direct electrolysis of the matte can also be carried out through a mixed chloride–sulfate electrolyte. The matte anodes corrode to produce a voluminous slime of elemental sulfur containing all the precious metal values, which are retained in a,Electrolytic reduction of zinc from acidic sulfate solutions,ELECTROLYTIC REDUCTION OF ZINC FROM ACIDIC SULFATE SOLUTIONS BY KENNETH DALE GIELOW, 1948-A THESIS Presented to the Faculty of the Graduate School of the UNIVERSITY OF MISSOURI-ROLLA In Partial Fulfillment of the Requirements for the Degree MASTER OF SCIENCE IN METALLURGICAL ENGINEERING 1971 Approved by ~ (Advisor) ii PUBLICATION THESIS OPTIONElectrowinning of Iron from Spent Leaching Solutions,A South African mining group is investigating the use of electrowinning (EW) to recover iron and H 2 SO 4 from an iron sulphate waste solution produced during metal beneficiation.
