United States Gypsum's Heath Plant, Harold L. Coolidge
United States Gypsum's Heath Plant, Harold L. Coolidge
Bachelors Theses and Reports, 1928 - 1970
The United States Gypsum Company's Heath plant, which is located at Heath, Montana, is one of forty-six diversified production facilities for the development and production of gypsum products. The Heath plant is located about twelve miles southeast of Lewistown, Montana, and consists of a mine, a mill and a boardplant. The Heath plant was built in 1925 by the Northwestern Gypsum Company.
Zinc Department Anaconda Reduction Works, Robert E. Morris
Zinc Department Anaconda Reduction Works, Robert E. Morris
Bachelors Theses and Reports, 1928 - 1970
The electrolytic zinc department of the Anaconda Reduction Works consists of five divisions, each responsible for one phase in the preparation of electrolytic zinc. These divisions are: (1) The zinc concentrator which produces a high-zinc, low-lead concentrate for further treatment at Anaconda, and a low-zinc, high-lead concentrate which is shipped to East Helena for further treatment. (2) The roasting division wherein the concentrate is roasted to oxides and sulfates. (3) The leaching division which (a) leaches the roasted concentrate to dissolve the zinc, and (b) purifies the leached solution. (4) The electrolytic division which produces pure zinc cathodes by electrowinning …
Design And Calibration Of A Ferromagnetic Torsion Balance, Oliver W. Moen
Design And Calibration Of A Ferromagnetic Torsion Balance, Oliver W. Moen
Bachelors Theses and Reports, 1928 - 1970
Magnetic materials can be divided into three major groups; diamagnetic, paramagnetic and ferromagnetic. From a magnetic point of view, the ferromagnetic are the most interesting. Ferromagnetic materials include the elements iron, nickel, cobalt, certain of the alloys of these elements and a group of alloys first studied by Huesler. These latter are ferromagnetic largely because of the presence of manganese in special combination with the other non-ferrous elements.
Application Of Amalgam Metallurgy To The Extraction Of Indium, John Zelem
Application Of Amalgam Metallurgy To The Extraction Of Indium, John Zelem
Bachelors Theses and Reports, 1928 - 1970
In view of the greater demand for indium with the progressive development of the metal, simpler methods of recovery are necessary. The author here hopes to apply mercury in the metallurgy of indium in an effort to find a simpler method of extraction.
Geology Of An Area Near Montana City, Montana, Frank A. Crowley
Geology Of An Area Near Montana City, Montana, Frank A. Crowley
Bachelors Theses and Reports, 1928 - 1970
The investigated area lies about five miles south of Helena, Montana, near the abandoned gold camp of Montana City. Topographically, the area reflects the sedimentary formations and the igneous rocks, quartz monzonite and rhyolite. Static recrystallization of the sedimentary rocks caused by the intrusion of the Boulder Batholith, along with deformation of sedimentary beds by pre-batholithic folding and by post-batholithic faulting have complicated the geologic picture.
The Placer Deposits Of The Siberia District (German Gulch), Montana, Ronald D. Karvinen
The Placer Deposits Of The Siberia District (German Gulch), Montana, Ronald D. Karvinen
Bachelors Theses and Reports, 1928 - 1970
The original concept of this problem was to determine if hidden or buried placers existed past the terminal point of the extensive placering in the Siberia District. Several theories have been advanced for the sudden cessation of those placers. All are plausible, and are both for and against an extended placer. The past history relates that some $13,000,000 in gold has been produced in the area, therefore stressing a practical search for additional accumulation.
Leaching As A Method Of Mining Uranium, Rob L. Kane
Leaching As A Method Of Mining Uranium, Rob L. Kane
Bachelors Theses and Reports, 1928 - 1970
This paper presents a new method of recovering uranium ores from the earth. By sinking drill holes into ore bearing beds, aqueous leach solutions can be circulated through the ores. Solutions of sulfuric acid, potassium carbonate and many other available reagents will put the ions of uranium and vanadium into the liquid leach. The pregnant solutions are then pumped to the surface so a recovery of the valuable portion of the ore can be made.
Shaft Sinking Investigation, Harold Foss
Shaft Sinking Investigation, Harold Foss
Bachelors Theses and Reports, 1928 - 1970
This paper, investigating shaft mucking, has been prepared as a partial requirement for the degree of Bachelor of Science in Mining Engineering. In the following material I have attempted to collect and compile all available information on mechanical shaft mucking, to compare and contrast the different methods and to trace their development through to the latest innovation. This development of the investigation is purposely being used to lead to a new method which will be discussed hypothetically as a conclusion to the paper.
Fluorite On The Wrong Font Claim, Robert L. Clayton
Fluorite On The Wrong Font Claim, Robert L. Clayton
Bachelors Theses and Reports, 1928 - 1970
The Wrong Front claim lies west of Butte near Nissler Junction. It is owned by Thomas J. Helehan of Butte. The deposit is epithermal and lies within the Boulder Batholith. The host rocks are granite, alaskite and andesite with granite being the most prominent host rock.
Beneficiation Of Scheelite Ore From The Potosi Tungsten Mining District, James A. Ndulue
Beneficiation Of Scheelite Ore From The Potosi Tungsten Mining District, James A. Ndulue
Bachelors Theses and Reports, 1928 - 1970
The now increasing importance of tungsten as a metal with desirable properties in high strength and high temperature resisting alloy steels, coupled with the recent discoveries of low-grade tungsten ore deposits in Montana, has spurred a search for suitable and economical methods of treating tungsten ores of the State. This search has been conducted on a variety of tungsten ores and the present work is rather an aspect of the whole tungsten beneficiation problem in Montana.
An Investigation Of A Dustless System Of Dry Drilling, Norman J. Hardt
An Investigation Of A Dustless System Of Dry Drilling, Norman J. Hardt
Bachelors Theses and Reports, 1928 - 1970
For many years the problem of removing dust particles while drilling dry has confronted the mining and construction industries. In areas where water is not available, rock drilling is still being done under hazardous dust conditions. It was in an attempt to find a partial solution to this problem that the material contained in this report was compounded.
Application Of The Rotary Principle To Underground Mucking, Walter J. Smit
Application Of The Rotary Principle To Underground Mucking, Walter J. Smit
Bachelors Theses and Reports, 1928 - 1970
Since the beginning of man's utilization of rocks and minerals, he has felt a need for an efficient mover of these materials. Thus, he turned from the sole use of his hands to the development of the shovel, and through the other hand tools-- the hoes, and the fork, and the rake-- he finally came to the manufacture of the heavy, more efficient, large-scale rock movers-- the muckers, and the scrapers, and duckbill loaders.
Geology Of A Mineralized Breccia "Pipe" Near Basin, Montana, James W. Allan
Geology Of A Mineralized Breccia "Pipe" Near Basin, Montana, James W. Allan
Bachelors Theses and Reports, 1928 - 1970
Located on the western flank of the Boulder batholith of southwestern Montana, the mineralized breccia "pipe" is opened by the Obelisk Mine. The intersection of two fault systems in the quartz monzonite of the Boulder batholith has provided the locus of the breccia "pipe". There is fairly conclusive evidence indicating that the present outcrop of the "pipe" lies only a few hundred feet below the former "roof" of the batholith.
Southwestern Extension Of The Pondera Field, Paul P. Garding
Southwestern Extension Of The Pondera Field, Paul P. Garding
Bachelors Theses and Reports, 1928 - 1970
Oil was discovered in the Pondera field in June 1927 following work done by E.B. Emrick. The initial discovery well, located in section 17, T. 27 N., R. 4 W., was not a commercial oil producer. Its initial production being 3 barrels of oil and 3,500,000 cubic feet of gas per day. Rapid expansion followed until 1929, when the field reached its peak of production.
Tungsten Mineralization At The Strawberry Mine, Pony, Montana, Robert L. Meyer
Tungsten Mineralization At The Strawberry Mine, Pony, Montana, Robert L. Meyer
Bachelors Theses and Reports, 1928 - 1970
The Strawberry Mine, located four miles west of Pony, Montana, for many years an intermittent producer of gold are, is once again the scene of mining activity due to the discovery of scheelite in 1953.
