The Occurrences Of Non-Metallic Minerals In Montana, Samuel T. Mitchell
The Occurrences Of Non-Metallic Minerals In Montana, Samuel T. Mitchell
Bachelors Theses and Reports, 1928 - 1970
This thesis is essentially an abstract of the literature concerning occurrences in Montana of minerals with a non-metallic luster. The discussions give a general description of the occurrences of minerals as reported by the various references, but is not complete as less than 40 percent of the non-metallic minerals known to exist in Montana are discussed.
Sulphidizing Of Cerussite, Emil A. Kovacevich
Sulphidizing Of Cerussite, Emil A. Kovacevich
Bachelors Theses and Reports, 1928 - 1970
The oxide minerals, such as cerussite, are not as amenable to flotation as the sulphide minerals. Sulphidization is the usual means used today to increase the recovery of an oxide flotation; however, sulphidization under the most advantageous conditions does not yield very satisfactory recoveries.
Differential Thermal Analysis Of Some Carbonate Minerals, Paul L. Vandeveer
Differential Thermal Analysis Of Some Carbonate Minerals, Paul L. Vandeveer
Bachelors Theses and Reports, 1928 - 1970
Thermal analysis is a relatively new method of determining the general composition of certain mineral substances. As is demonstrated by much of the literature previously written, clays and carbonates are especially adaptable to this method. The full importance of the method is not as yet realized, but it is rapidly approaching that point.
Metal Production From Ore Deposits In Different Host Rocks In Montana, Robert F. Gale
Metal Production From Ore Deposits In Different Host Rocks In Montana, Robert F. Gale
Bachelors Theses and Reports, 1928 - 1970
It is known that many different kinds of rocks serve as host to the ore deposits of Montana, but the relative importance of each of these kinds of rock as a host for ore deposits has never been described in any published report.
Chemical Analysis Of Igneous Rocks And Variation Diagrams Of Petrographic Provinces Of Montana, Frederick M. Hilpert
Chemical Analysis Of Igneous Rocks And Variation Diagrams Of Petrographic Provinces Of Montana, Frederick M. Hilpert
Bachelors Theses and Reports, 1928 - 1970
A total of 179 chemical analyses of igneous rocks are available for the state of Montana, but these analyses do not cover the entire state in a satisfactory manner. There has been an emphasis on the central part of the state, and an almost complete lack of interest in the southern portion of Montana.
The Electrolytic Purification Of An Impure Cadmium Sulfate Solution With A Cell Utilizing A Mercury Cathode And A Lead Anode, W. D. Mcmaster
The Electrolytic Purification Of An Impure Cadmium Sulfate Solution With A Cell Utilizing A Mercury Cathode And A Lead Anode, W. D. Mcmaster
Bachelors Theses and Reports, 1928 - 1970
Cadmium is produced solely as a by-product and all cadmium of commerce is obtained from zinc ores. It is a rare occurrence when zinc deposits are found which do not contain some cadmium.
Determination Of The Activities Of Indium And Mercury And The Vapor Pressures Of Mercury Over These Amalgams From 0.00216 To 0.02494 Mole Fraction Indium At 25 C And From 0.00067 To 0.02410 Mole Fraction Indium At 70 C By Electromotive Force Measurements, Arthur H. Lutts
Bachelors Theses and Reports, 1928 - 1970
This work was performed to determine by experimental means the activities of both indium and mercury and the vapor pressures of mercury over these amalgams at 25 and 70 C.
Electrowinning Versus Electrorefining Of Blister Copper, Frank J. Vorell
Electrowinning Versus Electrorefining Of Blister Copper, Frank J. Vorell
Bachelors Theses and Reports, 1928 - 1970
In the following sections of this report, I will discuss as fully as possible both the theoretical and practical aspects of the roasting, leaching, and electrowinning steps, as well as the economic considerations of the process. The results of my laboratory work will, of course, be integrated to the process.
The Construction Of A Ferromagnetic Torsion Balance, Elliott Willner
The Construction Of A Ferromagnetic Torsion Balance, Elliott Willner
Bachelors Theses and Reports, 1928 - 1970
The construction of the apparatus was performed entirely in the machine shops at the Montana School of Mines. The materials utilized in the construction were obtained through the courtesy of many sources: the A. C. M. Co., the Montana Power Co., and the Western Iron Works.
A Microscopic Study Of The Ore Minerals From The Mines In The Northern Part Of The Zosell (Emery) Mining District, John P. Joyce
A Microscopic Study Of The Ore Minerals From The Mines In The Northern Part Of The Zosell (Emery) Mining District, John P. Joyce
Bachelors Theses and Reports, 1928 - 1970
Any investigation of the many gold silver producing districts of Montana will necessarily include the name Zosell. The Zosell Mining District, often referred to as the Emery District, was never a major producer in the state; however, its location, history, type of deposit, and character of ore, has drawn the interest of many prominent investigators of the mineral industry.
Production Of Sponge Iron From Pyrites, Robert W. Leeson
Production Of Sponge Iron From Pyrites, Robert W. Leeson
Bachelors Theses and Reports, 1928 - 1970
The purpose of this thesis is to record and discuss the results of tests conducted, at the Montana School of Mines, in which pyrite concentrates from the Concentrator Department of the Anaconda Reduction Works, Anaconda, Montana, were subjected to the reducing effects of natural gas at elevated temperatures in an endeavor to produce iron in the metallic form.
Possible Mineral Resources University Land Grant, Montana School Of Mines Lands, Eugene S. Perry
Possible Mineral Resources University Land Grant, Montana School Of Mines Lands, Eugene S. Perry
Bachelors Theses and Reports, 1928 - 1970
The following evaluation of the mineral resources of the University Land-Grant lands has been made from an office study of geologic maps and published reports, and from a rather thorough knowledge of the geology of the state by the writer after 23 years of experience in the state.
