The Application Of Electric Energy To The Metallurgy Plants In Montana, Edwin J. Duncan
Bachelors Theses and Reports, 1928 - 1970
Since the year 1800, metallurgy has been affiliated with electricity. In fact, the two industries have grown side by side, being naturally dependent upon each other and having a parallel growth.
Geology Of The Marget Ann Mine Butte District, Montana, Winston Martin Sahinen
Geology Of The Marget Ann Mine Butte District, Montana, Winston Martin Sahinen
Bachelors Theses and Reports, 1928 - 1970
As the field work progressed it became apparent that very little was known of the mineralogical associations of the precious metal constituents of the Marget Ann ore. A mineralogical study in excess of that originally planned was then decided upon to determine the affiliations exhibited by the silver and gold. With these objectives in mind, the laboratory and field work continued.
Electrowinning With Amalgam Electrode, Ralph V. Anderson Jr.
Electrowinning With Amalgam Electrode, Ralph V. Anderson Jr.
Bachelors Theses and Reports, 1928 - 1970
Amalgam Metallurgy, a relatively new expression in the technology of metal extraction, was first chosen to describe certain new processes developed at the Duisburg Copper Works in Germany. The idea of using mercury, a costly and poisonous metal, as an intermediate in heavy chemical industry and in polarography are of recent origin; with the exception of a series of patents of little significance and occasional comments in the literature, the work is hardly known.

Vacuum Distillation Of Zinc And Cadmium From Zinc Leach Purification Cake, Stiles R. Slosson
Bachelors Theses and Reports, 1928 - 1970
The term "vacuum distillation" is used to describe the process employed when certain elements are separated either from their mother compounds or from one another by distilling them under reduced atmospheric pressure.
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.
Electro-Galvanizing From A Purified Ammonium Sulphate Leach Of Anaconda Zinc Calcine, Phillip J. Mischkot Jr.
Electro-Galvanizing From A Purified Ammonium Sulphate Leach Of Anaconda Zinc Calcine, Phillip J. Mischkot Jr.
Bachelors Theses and Reports, 1928 - 1970
Ever since the introduction of metal products into our civilization, especially those of iron and steel, man has been confronted with the problems of corrosion prevention. As the agents which are conducive to corrosion cannot be completely eliminated, it has been necessary for man to develop processes and materials that will retard the degeneration of the metals that are so important to our industrialized world.
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.
Mottling In The Meagher Limestone, Ronald J. White
Mottling In The Meagher Limestone, Ronald J. White
Bachelors Theses and Reports, 1928 - 1970
The middle Cambrian Meagher limestone of southwest Montana is characterized by mottled members that are finely crystalline in the tan part and microcrystalline in the dark matrix. As seen in the literature, similar mottled limestones are thought to be an arrested stage in the dolomitization, or alteration of limestones.
Purification Department Of Zinc Leaching Division At Anaconda, Montana, J. L. Brown
Purification Department Of Zinc Leaching Division At Anaconda, Montana, J. L. Brown
Bachelors Theses and Reports, 1928 - 1970
The original smelter, known as the Upper Works smelter, was located on the north side of the Warm Springs Creek, just 2 miles east of the city of Anaconda and 26 miles from the city of Butte. By the year 1894 this smelter had a capacity of 500 tons of ore a day.
The Vanadium Plant Of The Anaconda Reduction Works, Tom Liss
The Vanadium Plant Of The Anaconda Reduction Works, Tom Liss
Bachelors Theses and Reports, 1928 - 1970
No complete history of mining and smelting will ever be written that does not include a major discussion of the Butte district. The colorful tale of this area plays a major role in the interesting stories of mining. In the fields of mining methods, labor relations end financial manipulations, the Butte area has set a standard.
Manganese Oxide Deposits Near Butte And Development Since 1942, Emmett M. Gilmore
Manganese Oxide Deposits Near Butte And Development Since 1942, Emmett M. Gilmore
Bachelors Theses and Reports, 1928 - 1970
The manganese minerals occur in the peripheral zone of the Butte district with quartz in veins, which at depth contain galena and sphalerite closely associated with silver-bearing minerals. The manganese oxides are all oxidation products formed by weathering of primary rhodochrosite or rhodonite.
Geology Of The Lost Creek-Modesty Creek Area Deerlodge County, Montana, Howard B. Nickelson, Robert L. Pott
Geology Of The Lost Creek-Modesty Creek Area Deerlodge County, Montana, Howard B. Nickelson, Robert L. Pott
Bachelors Theses and Reports, 1928 - 1970
In 1915 the United States Geological Survey published a folio by Calkins and Emmons on the geology of the Philipsburg Quadrangle, which adjoins the area now under study to the west. Geology of this portion of Montana had not been mapped previously; consequently the purpose of this thesis is to make a geological reconnaissance of the stratigraphy and structure of the area.
Flotation Of A Complex Sulphide Ore Containing Tetrahedrite, James C. O'Dea, Lorimer W. Hoar
Flotation Of A Complex Sulphide Ore Containing Tetrahedrite, James C. O'Dea, Lorimer W. Hoar
Bachelors Theses and Reports, 1928 - 1970
The ore investigated in this thesis is a zinc-copper-lead ore. Microscopic analysis of this complex sulphide ore showed it to contain pyrite, sphalerite, arsenopyrite, galena, chalcopyrite, tetrahedrite, and covellite, with quartz as the gangue constituent.
Some Leaching Characteristics Of The Butte Rhodochrosite, W. L. Slosson
Some Leaching Characteristics Of The Butte Rhodochrosite, W. L. Slosson
Bachelors Theses and Reports, 1928 - 1970
With the increasing importance of manganese in the metallurgical fields of today and tomorrow, extensive work along the lines of its successful exploitation has been accomplished by many investigators. Since tie current world situation has shut off most of our supply of high-grade manganese ores from foreign sources, the low-grade domestic deposits have entered the fields of investigation very rapidly.
The General Geology Of The Cardwell Mining District, Clyde Congdon
The General Geology Of The Cardwell Mining District, Clyde Congdon
Bachelors Theses and Reports, 1928 - 1970
The Cardwell Mining District is part of the greater Whitehall Mining District. The district is situated about four miles to the east and northeast of Whitehall in the southern end of the Bull Mountains which are near the Continental Divide. The first reported production was in 1896 after the discovery of the Mayflower Mine. Mining has been carried on intermittently and on a small scale since that time.
The Geology Of Lost Creek Canyon With Special Reference To Igneous Activity, John Kolesar
The Geology Of Lost Creek Canyon With Special Reference To Igneous Activity, John Kolesar
Bachelors Theses and Reports, 1928 - 1970
This investigation was undertaken primarily as a problem in geologic mapping, coupled with a study of stratigraphy, glaciation, igneous phenomena, and structure. The area is admirably suited to a study of geology and geologic events. Because it is small in extent, the area was studied in some detail during the time which was devoted to field work. The record of igneous activity of past geological ages is remarkably well exposed, since Lost Creek Canyon was carved through the roof of a stock or batholith by the glaciers of the Pleistocene epoch.
The Effect Of Impurities On The Electrodeposition Of Zinc From Zinc Sulfate Solution Containing Antimony., Emmitt L. Klebba
The Effect Of Impurities On The Electrodeposition Of Zinc From Zinc Sulfate Solution Containing Antimony., Emmitt L. Klebba
Bachelors Theses and Reports, 1928 - 1970
It has been proven by research and years of experience, that before electrolytic zinc is possible, the electrolyte, as zinc sulfate solution must be prepared as pure as is economical. In other words, the ideal electrolyte must only be a solution of one metal - zinc. Every other metal and carbon must be excluded if good recovery and a firm deposit is to be obtained.
