Polarographic Determination Of Germanium, Calvin Leo Stevenson
Polarographic Determination Of Germanium, Calvin Leo Stevenson
Bachelors Theses and Reports, 1928 - 1970
In the past germanium has been determined by either wet methods or by the spectograph; the spectograph being used for the determination of very small amounts of germanium and wet methods used when more than one hundredth of one percent germanium is present. Both of these analytical schemes have weaknesses.
A Study Of The Effects Of The Chloride Ion On The Lead-Silver Anodes And On The Lead Tenor Of The Zinc Deposit In Zinc Electrolysis, William A. Mitchell
A Study Of The Effects Of The Chloride Ion On The Lead-Silver Anodes And On The Lead Tenor Of The Zinc Deposit In Zinc Electrolysis, William A. Mitchell
Bachelors Theses and Reports, 1928 - 1970
The electrolyte used in the commercial production of electrolytic zinc from zinc sulphate solutions contains small amounts of impurities each of which has its own effects upon the process. Impurities such as antimony, cobalt, nickel, and iron tend to lower the current efficiency while other impurities such as chlorine, fluorine, and nitrates tend to increase the corrosion of the lead anodes and thereby increase the lead tenor of the zinc deposit.
The Decomposition Of Calcium Tungstate And Synthetic Scheelite With Hydrochloric Acid, Robert R. Beebe
The Decomposition Of Calcium Tungstate And Synthetic Scheelite With Hydrochloric Acid, Robert R. Beebe
Bachelors Theses and Reports, 1928 - 1970
The decomposition of scheelite with hydrochloric acid was studied under conditions of variable acid concentration, time and temperature. The reactions were traced by weighing material untransformed and, in some cases, by analyzing the transformation products.
A Study Of The Beneficiation Of Low-Grade Domestic Chromite, Darrell Edward Bodie
A Study Of The Beneficiation Of Low-Grade Domestic Chromite, Darrell Edward Bodie
Bachelors Theses and Reports, 1928 - 1970
Chromite, a strategic mineral, is being consumed in ever increasing quantities in the United States today. Although the United States imports practically all of the chromite that is being consumed, it is gradually becoming necessary to exploit the low-grade deposits that are located within the United States, and also the low-grade deposits of Canada.
