Study of Manganese and Phosphoric Acid on Dimensionally Stable Anodes During Zinc Electrowinning

Materials and Corrosion, Volume 76, Issue 11, Page 1697-1708, November 2025.
During zinc electrowinning, the manganese oxide covers the surfaces of the dimensionally stable anodes (DSA) and decreases their electrocatalytic performance. Phosphoric acid is added into the zinc electrolyte to complex the manganic ion and hence reduce

Continuous electrowinning of zinc

Hydrometallurgy, 2000
Abstract Synthetic and pure zinc solution produced from laboratory leached oxidised zinc ores, under controlled temperature and pH were subjected to continuous elctrowinning operations until the least possible zinc concentration was reached. Conventional DC electrolysis technique, PC and PCR procedures were examined.

Spouted bed electrowinning of zinc: Part I. Laboratory-scale electrowinning experiments

Metallurgical and Materials Transactions B, 1997
Two types of laboratory cells have been constructed to electrowin zinc from sulfate electrolytes: one cell was cylindrical while the other had a rectangular (flat) geometry. Cells were operated on industrial or synthetic electrolytes to electrodeposit zinc onto a spouted bed of zinc particles in the range of 0.75 to 1.45 mm.

Electrowinning of zinc from alkaline solutions

Journal of Applied Electrochemistry, 1986
The objective of this work was to determine the best conditions for minimizing energy consumption in zinc electrowinning from alkaline solutions. The effects of several variables, i.e. hydroxide concentration (300–500 gl−1), current density (50–1000 A m−2), temperature (24–74°C), cathode material (magnesium, nickel, lead, stainless steels 304 and 316 ...

Zinc electrowinning from aqueous chloride electrolytes

Journal of Applied Electrochemistry, 1983
Smooth, compact, dendrite-free zinc deposits can be electrowon from acid zinc chloride electrolyte using a diaphragm cell featuring catholyte agitation by air sparging. A correlation exists between the degree of zinc deposition polarization and the zinc deposit structure and orientation that can be used to evaluate the effectiveness of addition agents ...

Reducing power consumption in zinc electrowinning

JOM, 2009
Approximately 7 million tons per annum of zinc are produced globally by traditional electrowinning which is a power intensive process. Power consumption is directly proportional to cell voltage which is thermodynamically limited to the potential difference between the oxygen evolution and zinc reduction reactions.

Evaluating additives and impurities in zinc electrowinning

JOM, 1995
The zinc electrowinning (EW) process is very sensitive to the presence of impurities. There is only one EW plant in the world that we know of that operates at moderate current efficiency and deposition times without using any additives. All the others must use them continuously.
