The Effect Of The Fe2: Fe3 Ratio Upon The Current Efficiency In The Electrolysis Of A Copper Sulfate Solution Containing Iron Sulfate, Roy Macfarland Jun 1932

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 Electrolytic Deposition Of Chromium Upon Aluminum, E. Fults, L. D. Voerge May 1932

The Electrolytic Deposition Of Chromium Upon Aluminum, E. Fults, L. D. Voerge

Bachelors Theses and Reports, 1928 - 1970

The purpose or this investigation is primarily to determine the best conditions for plating chromium on aluminum. The work was carried out with the hope of obtaining coherent deposits, and of determin­ing the conditions under which such deposits may be duplicated.
