An Investigation Of The Precipitation Of Cobalt With Zinc Dust, Lyle Hallberg
An Investigation Of The Precipitation Of Cobalt With Zinc Dust, Lyle Hallberg
Bachelors Theses and Reports, 1928 - 1970
Cobalt, as well as copper, cadmium, and other impurities, is removed by selective precipitation with zinc during the zinc electrolyte purification cycle, and the purification residue may be treated by a Cadmium Plant for the recovery of cadmium.
Age Hardening Of Copper Antimony Alloys, William R. Stern
Age Hardening Of Copper Antimony Alloys, William R. Stern
Bachelors Theses and Reports, 1928 - 1970
A large number of alloys of varying percentages of copper and antimony were prepared. These alloys were treated in various ways which might be expected to produce age hardening. The effect of cold working was studied in the range where the alloys were malleable.
Some Effects Of The Addition Of Tellurium To Lead Alloys, Selim Ozsahin
Some Effects Of The Addition Of Tellurium To Lead Alloys, Selim Ozsahin
Bachelors Theses and Reports, 1928 - 1970
From the standpoint of its practical usefulness, the most important characteristics of metallic lead are its cheapness, resistance to corrosion, plasticity, high specific gravity, low melting point, and its ability to form alloys in which some properties are modified by the addition of other elements, while other properties remain the same.
The Measurement Of Current Efficiency In Zinc Sulphate Electrolytes Containing Antimony And Cobalt By Hydrogen Evolution, Arthur R. Hard
The Measurement Of Current Efficiency In Zinc Sulphate Electrolytes Containing Antimony And Cobalt By Hydrogen Evolution, Arthur R. Hard
Bachelors Theses and Reports, 1928 - 1970
The measurement of current efficiency by hydrogen evolution is based on the assumption that the portion of the current which deposits no zinc will release hydrogen. This assumption is correct for solutions containing no impurities electropositive to zinc.
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.
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.
