The Effect Of The Fe2: Fe3 Ratio Upon The Current Efficiency In The Electrolysis Of A Copper Sulfate Solution Containing Iron Sulfate, Roy Macfarland
The Effect Of The Fe2: Fe3 Ratio Upon The Current Efficiency In The Electrolysis Of A Copper Sulfate Solution Containing Iron Sulfate, Roy Macfarland
Bachelors Theses and Reports, 1928 - 1970
In the treatment of copper ores by hydro-electro-metallurgical methods, not only is copper deposited, but other metals are also dissolved. In practice it has been found* that iron, under certain conditions, causes the copper to deposit on the cathode as a nonadherent precipitate and also that the iron in solution causes a great decrease in current efficiency, especially when the electrolysis is conducted by operating with a higher current density at the cathode than at the anode.
The present investigation deals with the effects of the two valences of iron on the current efficiency and endeavors to determine whether or …

The Effect Of Hydrogen Overvoltage On The Electrolytic Deposition Of Zinc, John M. Munzenrider, Kenneth O. Sweeney
Bachelors Theses and Reports, 1928 - 1970
In the deposition of metallic zinc by electrolysis from neutral or acid solution, little difficulty is experienced provided certain impurities are absent from the electrolyte. The use of the process has long been considered as a potential source, patents on the process having been issued as early as 1880. However, the early experimenters failed to realize the importance of impurities in the electrolyte, and for this reason, the process suffered several severe setbacks when commercial plants were built.
