Possible Mineral Resources University Land Grant, Montana State University 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.

Studies Of Antimony Occurrence With Special Relation To Its Effective Extraction, San Jose Antimony Mines, Wadley, San Luis Potosi, Mexico, J. C. Archibald Jr.

Bachelors Theses and Reports, 1928 - 1970

The mines at San Jose which are within the Wadley unit are the largest antimony mines in Mexico. These mines produce more than half of the antimony produced by the company from its mining operations. Since the time of the author's connection with the company, a number of changes have been made in planning of development work, handling of labor, methods of mine development, cost improvement, and other problems inherent in the successful guidance of an operation.

An Investigation Of Ruthenium As A Possible Ceramic Colorant, John Charles Williams

Masters Theses

"Some portion of almost every writing dealing with the historical development of ceramic products is devoted to describing the application of colors as found on even the most ancient specimens known to exist. A vase bearing the name of an Egyptian king living 5000 B. C. was glazed in green and inlaid with purple. There are many such examples of the utilization of color in ceramics which illustrate to a certain extent the aesthetic tastes of the very earliest and primitive civilizations.

In those early times, only a few elements were known and available that could be used for such …

A Study Of Some Raw Materials For The Manufacture Of Silica Brick, Charles E. Shulze

Masters Theses

"The ability of silica to carry a load to within a few degrees of its melting point and its tolerance for comparatively high concentrations of iron oxide and lime, have enabled it to maintain its position as the number one steelplant refractory. It is estimated that at least half of the volume of refractories used in the steel plant are silica bricks. Consequently the manufacture of silica refractories forms an industry of considerable importance.

Raw materials suitable for the manufacture of silica brick are widely distributed, but only a small number of deposits are used commercially for one reason or …

Bauxite Versus Diaspore Clay In High Alumina (70%) Refractory Brick, Bhikhubhai Mahadeo Sedalia

Masters Theses

"The last twenty five years have seen a remarkable change in the character and types of refractories for furnace construction. Not much more than a few years ago, the production of refractories consisted almost solely of fireclay and silica shapes. A few high alumina bricks were made from Missouri diaspore clays or from bauxite and fire clays. At a later date, although little used, high alumina refractories were available which were made from alumina of a higher degree of purity, by the fusion process. Today refractories covering the entire range of composition from about 98% SiO₂ to 99 1/2% …
