The Electrodeposition Of Iron-Manganese Alloys, Kenneth H. Larson
The Electrodeposition Of Iron-Manganese Alloys, Kenneth H. Larson
Bachelors Theses and Reports, 1928 - 1970
Although the alteration of properties resulting from the alloying of metals in their usual commercial forms has been extensively investigated, the field of electrodeposition of alloys is believed generally not to have received the attention that it merits.
The Electrodeposition Of Iron-Manganese Alloys, Earl C. Roberts
The Electrodeposition Of Iron-Manganese Alloys, Earl C. Roberts
Bachelors Theses and Reports, 1928 - 1970
Various electrolytes were experimented with in an attempt to deposit an iron-manganese alloy. An Alloy was obtained from a solution containing ferrous ammonium sulfate, manganous sulfate, and ammonium sulfate. Further experimentation was done in an effort to determine the optimum conditions of deposition and the highest manganese alloy which could be produced.
Alkali Leaching Of Antimony Sulphide And Electrolytic Recovery Of Antimony From The Resulting Leach Solution, Vincent J. Andrews
Alkali Leaching Of Antimony Sulphide And Electrolytic Recovery Of Antimony From The Resulting Leach Solution, Vincent J. Andrews
Bachelors Theses and Reports, 1928 - 1970
It is the purpose of this investigation to obtain some insight into optimum conditions for leaching Stibnite with sodium hydroxide solution and also to steady the factors affecting the electrolysis of the resulting solution.
Electrolytic Recovery Of Copper And Zinc From Brass, D. H. Swank
Electrolytic Recovery Of Copper And Zinc From Brass, D. H. Swank
Bachelors Theses and Reports, 1928 - 1970
The purpose of this research was to continue the work of Thomas Parker, who worked on the recovery of copper and zinc from brass during the school year l934 - 1935. Since there is such a wide variety of brasses made with usually a third alloying constituent, remelted scrap is suitable only for castings of wide tolerance in specifications.
The Electrodeposition Of Manganese From Certain Aqueous Solutions, Fred J. Hill
The Electrodeposition Of Manganese From Certain Aqueous Solutions, Fred J. Hill
Bachelors Theses and Reports, 1928 - 1970
Careful examination of the literature available shows that the electrodeposition of manganese from various aqueous solutions has not been attempted to any great extent. The best method for the electrodeposition of pure manganese consists in the electrolysis of a solution containing manganous and ammonium sulphates.
The Effect Of Impurities On The Electrodeposition Of Zinc From Zinc Sulfate Solution Containing Antimony., Emmitt L. Klebba
The Effect Of Impurities On The Electrodeposition Of Zinc From Zinc Sulfate Solution Containing Antimony., Emmitt L. Klebba
Bachelors Theses and Reports, 1928 - 1970
It has been proven by research and years of experience, that before electrolytic zinc is possible, the electrolyte, as zinc sulfate solution must be prepared as pure as is economical. In other words, the ideal electrolyte must only be a solution of one metal - zinc. Every other metal and carbon must be excluded if good recovery and a firm deposit is to be obtained.
Effect Of Impurities Upon Current Efficiency In The Electrolysis Of Zinc Sulphate Solution, Robert Jess Smith
Effect Of Impurities Upon Current Efficiency In The Electrolysis Of Zinc Sulphate Solution, Robert Jess Smith
Bachelors Theses and Reports, 1928 - 1970
There are many elements which are detrimental to the current efficiency in the electrolysis of zinc sulphate solution. Fortunately the majority of these elements are easily removed in the purification process and cause no further trouble. The elements that are likely to cause trouble in ordinary plant operations are antimony, arsenic, cobalt, nickel, manganese and germanium. The following tests were made to determine the mutual effect on the current efficiency when several of the impurities were present in the electrolyte.
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
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.
The Effect Of Cobalt Upon Current Efficiency In The Electrolysis Of Zinc Sulphate Solutions, Joseph Newton, Louis Sanders Nuckols
The Effect Of Cobalt Upon Current Efficiency In The Electrolysis Of Zinc Sulphate Solutions, Joseph Newton, Louis Sanders Nuckols
Bachelors Theses and Reports, 1928 - 1970
The detrimental effect of the presence of cobalt upon the current efficiency, in the commercial production of zinc by electrolysis, has been recognized for some time. Most authorities differ upon the maximum amount of cobalt allowable. This is due to the fact that the presence of other impurities either increases or diminishes the detrimental effects of the cobalt.
The following tests were made with the object in view of ascertaining the relation, if any, between the amount of cobalt present and the current efficiency during the electrolysis of an otherwise pure zinc sulfate solution.
The results obtained from these observations …
