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.
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.
