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 …
