The Sedimentary Petrography Of The Oil And Gas Producing Horizons In Montana, Patrick J. Donahue
The Sedimentary Petrography Of The Oil And Gas Producing Horizons In Montana, Patrick J. Donahue
Bachelors Theses and Reports, 1928 - 1970
Montana is an excellent oil province, as oil and gas are produced from a wider range of beds in the geologic section than in any other district in the United States. (1,864) Commercial fields have been developed in Ordovician, Devonian, Mississippian, Pennsylvanian, Jurassic, Lower Cretaceous, and Upper Cretaceous. It is believed that by describing the physical characteristics of the producing horizons, and by placing this information in one compact volume, a better understanding of oil and gas occurrence in Montana may be gained.

The Birdie Mine Tungsten Deposit Butte Mining District, Silverbow County, Montana, Bernard A. Fahm
Bachelors Theses and Reports, 1928 - 1970
The importance of tungsten has encouraged the search for minerals of this metal, and consequently new deposits have been discovered, and known deposits have been re-examined. Western Montana has rather widespread deposits if low-grade types are also considered. Many deposits were known long ago, but abandoned because the use of tungsten was still in its beginning stage and therefore little attention was given to this type of mineral.

The Effect Of Ferric Iron Upon The Current Efficiency And The Deposition Of Copper In The Electrowinning Of Copper From Copper Sulphate Solutions, James L. Owings
The Effect Of Ferric Iron Upon The Current Efficiency And The Deposition Of Copper In The Electrowinning Of Copper From Copper Sulphate Solutions, James L. Owings
Bachelors Theses and Reports, 1928 - 1970
In the hydrometallurgy of copper, probably the most widely used method for the precipitation of copper is by electrolysis using insoluble anodes. The process is similar in many respects to the electrolytic refining of copper; one of the main differences is the use of insoluble anodes in electrowinning as compared to the use of impure copper anodes in electrorefining. Impurities, however, are common to both processes. The nature of these impurities differ and the problem of purifying the electrolyte is also different.

An Investigation Of The Deformation Textures Of Titanium, Dean Nesbit Williams
An Investigation Of The Deformation Textures Of Titanium, Dean Nesbit Williams
Doctoral Dissertations
"With the increase in production of titanium in recent years has come a great interest in the mechanical properties and in the possible uses of this metal. Due to the affinity of titanium for oxygen, nitrogen, carbon, and hydrogen, and the market effect of these elements on the mechanical properties, much of the work previously reported is unreliable. As purer commercial grades of titanium and high purity iodide titanium have become available for examination, research has been undertaken to correct and expand the knowledge of the properties of titanium. Although the uses of titanium are limited at the present time, …

Determination Of Progressive Corrosion Of Clay Flux Blocks, Ved Prakash Maheshwary
Doctoral Dissertations
"The Problem. Corrosion of refractories by molten corrosive liquids like molten slags and glasses is of general occurrence in those parts of the furnaces where they come in contact with the liquids. The life of a furnace generally depends upon the progressive rate of corrosion of the refractories by the slags and glasses. There have been various methods used by the investigators to ascertain the useful life of a refractory product before its use in the furnaces, but the problem is so complex that even after decades of research work by the research engineers and technologists a satisfactory and easy …
A Study Of The Dissolution Of Titanium In Acids With Ammonium Fluoride Added, Charles Burroughs Gill
A Study Of The Dissolution Of Titanium In Acids With Ammonium Fluoride Added, Charles Burroughs Gill
Doctoral Dissertations
"Titanium can no longer be considered a rare metal, even though the modern era of its production came into being only a few years ago. The first discovery of titanium was in 1791 by an English clergyman, the Reverend William Gregor, and the name titanium became universally adopted when so called by a German mineralogist, Martin Klaproth, who rediscovered titanium three years later. Not until 1887 was the relatively pure, 75 percent, metal prepared by L. F. Nilson and O. Pettersson, whose experiments were repeated in 1910 by M. A. Hunter. Hunter is given credit for producing the first metallic …

X-Ray Studies Of Zirconium Cyanonitride, John T. Ballass
Masters Theses
"The purpose of this research was to study, by means of x-ray and metallographic analysis, a material reported to be zirconium cyanonitride.
The x-ray analysis had a three fold purpose, the determination of the symmetry of the constituents, the number of phases present, and the crystal structure type. Metallography was used to confirm some of the results obtained by x-ray analysis establishing certain definite phase relationships present in the microstructure.
The sample investigated contained three principal elements namely zirconium, nitrogen, and carbon. On the basis of constitution this work is a contribution toward the development of the three component equilibrum …
Dissociation And Relative Stability Of Sodium Fluotitanate, Walter L. Gage
Dissociation And Relative Stability Of Sodium Fluotitanate, Walter L. Gage
Masters Theses
"Titanium is urgently needed in the armament industry especially as a substitute for 18-8 stainless steel. There would be an almost inexhaustible supply of ores of titanium if high-purity titanium metal could be produced economically in large quantities. The use of titanium would permit much of the scarce nickel and chromium to be made available for other important uses.
It has been found by H. C. Kawecki and E. J. Bielecki that high-purity Na2TiF6, K2TiF6, and (NH4)2TiF6 can be produced from iron-bearing titaniferous raw material, ilmenite ores, or a …
Activation Energy For Recrystallization In Rolled Silver, Krishan Kumar Tangri
Activation Energy For Recrystallization In Rolled Silver, Krishan Kumar Tangri
Masters Theses
"In several metals the process of recrystallization is accompanied by a change in the orientation of the recrystallized material with respect to the cold rolled material. If the change is sufficiently large, the changing position of the crystals can be determined by measuring the change in the intensity of the characteristic Bragg-reflection with a Geiger counter x-ray spectrometer. Recent determinations of the activation energies of copper and a 50/50 iron-nickel alloy have been made by using this x-ray technique. Both of these metals show a decided shift in the orientation as the material is recrystallized.
Silver was examined to find …
Direct Reduction Of Zinc Sulfide Under Vacuum, Merritt E. Langston
Direct Reduction Of Zinc Sulfide Under Vacuum, Merritt E. Langston
Masters Theses
"The present work is a continuation of the previous investigations of Gross and Warrington and Liu in which the effect of various reducing agents on the vacuum reduction of zinc sulfide was studied. The author became interested in this topic while reading the papers by these investigators in which they recommended that further work be performed in an attempt to prevent zinc sulfide from distilling over during reduction, thereby contaminating the zinc condensate. The original plan was to perform a few runs for the purpose of duplicating the results that were reported by Liu, and from this point carry on …
The Effect Of Impeller Speed And Air-Volume On The Flotation Rate With Respect To Particle Size, William Edward Horst
The Effect Of Impeller Speed And Air-Volume On The Flotation Rate With Respect To Particle Size, William Edward Horst
Masters Theses
"Today the ore being mined is low grade and the mineralization has become very complex. In order to concentrate a complex ore, the requirement of grinding the ore very fine is imposed. The process of flotation was developed to concentrate the finely ground ore particles; however, the finer size fractions of the ore still present a concentrating problem.
The fact has been established that the flotation rate which is the recovery that can be attained during a given time interval varies with particle size. The flotation rate increases with an increase in particle size until the maximum flotation rate is …
