The Flotation Concentration Of A Complex Low-Grade Lead Zinc Ore, Edward James Fong May 1953

The Flotation Concentration Of A Complex Low-Grade Lead Zinc Ore, Edward James Fong

Bachelors Theses and Reports, 1928 - 1970

This report is concerned primarily with the beneficiation of a low-grade complex lead-zinc ore. The depletion of high grade veins has caused the mineral engineer to seek deposits deeper in the earth's crust or to find lower grade deposits. The other alternative has placed more research problems on Mineral Dressing Engineers in particularly the iron, copper, lead and zinc fields.

Concentration Of Tungsten Ore From The Potosi Mining District, Ted S. Jordan

Bachelors Theses and Reports, 1928 - 1970

Tungsten is a strategic metal which, at present, is in short supply in the United States. In addition to its need in the defense effort, tungsten is becoming more and more in industrial demand and, as an increasing number of uses for this element are being found, so must additional sources of it be discovered and processed.


The Effect Of Germanium On The Current Efficiency In The Electrolysis Of Pure Zinc Sulfate Solution, Keith R. Bock May 1953

The Effect Of Germanium On The Current Efficiency In The Electrolysis Of Pure Zinc Sulfate Solution, Keith R. Bock

Bachelors Theses and Reports, 1928 - 1970

It has long been recognized that electrolytic zinc cells are extremely sensitive to impurities. In fact, cer­tain impurities present in amounts as low as 0.1 mg/1 cause a serious loss of current efficiency. Also, the presence of several impurities in the electrolyte may accelerate the detrimental effect of each impurity.

Oil Shales In Montana, Richard N. Miller Feb 1953

Oil Shales In Montana, Richard N. Miller

Bachelors Theses and Reports, 1928 - 1970

Montana has long been known to have very large resources of coal and oil, and undetermined amounts of oil shale. The reserves of coal and oil have been proven, in part, and have been produced commercially, but not much is known about the extent and apparent value of the oil shales. Under present .conditions, and according to standards set by the United States Bureau of Mines, the shales are not of commercial value. They are, however, a potentially valuable mineral resource, and portions of them will possibly be utilized, although not in the near future.
