The Mechanical Production Of Zinc Dust, Charles A. Schroer
The Mechanical Production Of Zinc Dust, Charles A. Schroer
Bachelors Theses and Reports, 1928 - 1970
The object of this thesis is to produce zinc dust suitable for zinc leach purification, by direct application of a mechanical force on a stream of molten zinc.The project is a continuation of work done by Mr. D. S. Gleason, while working for his Master of Science degree in the spring of 1952.
Flotation Of Huebnerite, Henry Albright
Flotation Of Huebnerite, Henry Albright
Bachelors Theses and Reports, 1928 - 1970
The development of suitable beneficiation processes for treating domestic low-grade tungsten ores is a problem now facing the mineral industry. While we are now consuming more tungsten than normally because of the defense program, we are no longer able to import ores from the world's principal source, China. The problem then, is to increase our domestic production so as to acquire a greater degree of self-sufficiency.
The Birdie Mine Tungsten Deposit Butte Mining District, Silverbow County, Montana, Bernard A. Fahm
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 Construction Of An X-Ray Camera, Emil Bazarnicki
The Construction Of An X-Ray Camera, Emil Bazarnicki
Bachelors Theses and Reports, 1928 - 1970
The major portion of the construction of the X-ray camera was performed in the machine shop of Montana School of Mines. However, some machine work had to be accomplished in the Butte High Machine Shop, as well as in the machine shop of the Anaconda Copper Mining Company.
Variation Of Induction And Hysteresis Curves For The Heusler Alloy, Cu2mna1, Ford W. Knight
Variation Of Induction And Hysteresis Curves For The Heusler Alloy, Cu2mna1, Ford W. Knight
Bachelors Theses and Reports, 1928 - 1970
The purpose of this investigation is to determine the fundamental magnetic characteristics of induction and hysteresis, for the alloy Cu2MnAl. This is a ternary, ferromagnetic Heusler alloy. The problem is not only to determine these characteristics for the alloy as-cast but to heat treat it and observe the manner in which different heat treatments affect these two fundamental magnetic characteristics.
Electrowinning Of Zinc By Mercury Cathode, Tor O. Notevarp
Electrowinning Of Zinc By Mercury Cathode, Tor O. Notevarp
Bachelors Theses and Reports, 1928 - 1970
The problem was the investigation of electrowinning of zinc by using a mercury cathode, employing a neutral solution of zinc sulphate and containing small amounts of zinc, in the order of ten grams zinc per liter and less. The purpose of this study was on the base of the laboratory experiments to investigate the operational data that might possibly be applied in practice or industry.
The Mechanical Production Of Zinc Dust, Robert F. Payne
The Mechanical Production Of Zinc Dust, Robert F. Payne
Bachelors Theses and Reports, 1928 - 1970
It was the purpose of this investigation to delve further into the possibility of producing, by mechanical means, a zinc dust which might be suitable for the purification of zinc leach solution.
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.
The Immersion Coating Of Indium Upon Magnesium From Sulphate Solutions Containing Flourides, John J. Harrington
The Immersion Coating Of Indium Upon Magnesium From Sulphate Solutions Containing Flourides, John J. Harrington
Bachelors Theses and Reports, 1928 - 1970
The thesis problem that will be discussed in this report is an investigation of a method of plating a coating of indium upon magnesium and magnesium alloys. The method used to accomplish the final results is the immersion process. It can be defined as the process of coating a metal with a second metal by immersing the first in a solution containing ions of the second.
The Occurrence Of Molybdenite In The United States, Alaska, Canada, And Newfoundland, Richard W. Brummett
The Occurrence Of Molybdenite In The United States, Alaska, Canada, And Newfoundland, Richard W. Brummett
Bachelors Theses and Reports, 1928 - 1970
In this study of molybdenite and its occurrence, the published literature on 66 separate deposits was reviewed, summarized, and coordinated. The following descriptions are intended to point out the important features of molybdenite occurrences as described in the literature.
The Metallography Of Aluminum Casting Alloys, Donald D. Goehler
The Metallography Of Aluminum Casting Alloys, Donald D. Goehler
Bachelors Theses and Reports, 1928 - 1970
The purpose of this thesis is to supply the Montana School of Mines with an up to date source of information concerning the metallography of aluminum casting alloys. This thesis is designed as a continuing project. Ultimately, it is hoped that a catalog containing all the typical structures of aluminum casting alloys will develop.
An Investigation Of The Hardening Properties Of Some Alpha Copper Indium Alloys, Charles W. Mcpherson
An Investigation Of The Hardening Properties Of Some Alpha Copper Indium Alloys, Charles W. Mcpherson
Bachelors Theses and Reports, 1928 - 1970
Precipitation hardening alloys has assumed a major role in modern day development of alloys. In his search for stronger, harder materials, the metallurgist has often been limited by the cost of metals which posses the needed properties.
Electroplating Of Chromium, Nickel And Copper Upon Titanium, Stanley O. Fong
Electroplating Of Chromium, Nickel And Copper Upon Titanium, Stanley O. Fong
Bachelors Theses and Reports, 1928 - 1970
Recently, there has been a great amount of research work done on the metal titanium. Since it is a light weight metal, with unusual strength and good resistance to corrosion, it may be a possible substitute for aluminum and magnesium alloys, or steel.
An Early Tertiary Stream Channel Between Fish And Pipestone Creeks, Ten Miles West Of Whitehall, Montana, Henry D. Olson
An Early Tertiary Stream Channel Between Fish And Pipestone Creeks, Ten Miles West Of Whitehall, Montana, Henry D. Olson
Bachelors Theses and Reports, 1928 - 1970
Driving between Butte, and Whitehall, Montana, on highway U.S. 10S, one observes an interesting phenomenon in the lower end of Little Pipestone Creek canyon. One side and the bottom of the canyon is cut inthe hard igneous rocks of the Boulder Batholith, and the other side of the canyon is made of unconsolidated sand, gravel, and cobbles.
