A Study Of The Transportation Of Mine Rock By Pumping, Howard Morris Fowler Jan 1947

A Study Of The Transportation Of Mine Rock By Pumping, Howard Morris Fowler

Masters Theses

"The conclusions arrived at in regard to the practicability of utilizing pumps instead of skip haulage for the removal of ore and waste from mines are entirely theoretical, as it was impossible to make actual conparative runs. These results were arrived at by comparing known or estimated costs for both types of operations. The abrasion studies were conducted in the laboratory of the Mining Department at the School of Mines and Metallurgy. The pressure tank was designed in an effort to counteract the present necessity for using single stage pumps in sand pumping, and to find a means for eliminating …

Rapid Determination Of Alumina In Diaspore Clays, Matthew Julius Kerper Jan 1947

Rapid Determination Of Alumina In Diaspore Clays, Matthew Julius Kerper

Masters Theses

"The alumina content of the diaspore clay is the index to its refractoriness, so it is important to know the alumina content of the diaspore clay. Diaspore is mined in comparatively small pits and naturally the alumina content will vary from pit to pit and will vary to a considerable extent in the same pit. Since a uniform finished product is desired, the alumina content of each pit must be known and frequent checks run on the output of the pits. Chemical analysis is the standard method of determining the amount of alumina in clays. The main objections to chemical …

A Study Of The Chemical Behavior Of Some Natural Occurring Iron Disulfide Ores, William Louis Shivelbine Jan 1947

A Study Of The Chemical Behavior Of Some Natural Occurring Iron Disulfide Ores, William Louis Shivelbine

Masters Theses

"A complete investigation of the pyrites deposits of Missouri by Grawe has revealed many large deposits of pyrites available in commercial quantities in the Ozark area. The pyrites has been found occurring in contact with several various types of minerals. In the northcentral Ozark Plateau, pyrites is found associated with hematite-bearing sink structures. In the northwest part of the state, pyrites occurs in coal deposits, which, in the future, may be recovered as a by-product in the production and preparation of coal. Some pyrites, chiefly marcasite, has been found as fracture and cavity fillings in several other districts. The purpose …

Beneficiation Of A Zinc Rich Oxidized Ore From Nuevo LéOn, MéXico, Jorge Casas Nieto Jan 1947

Beneficiation Of A Zinc Rich Oxidized Ore From Nuevo LéOn, MéXico, Jorge Casas Nieto

Masters Theses

"Rich zinc ores are relatively rare now in this country but are still abundant in countries like México, that have not yet developed all their mineral potentialities. In almost all Mexican zinc districts there has been reported sporadic production of oxidized ores, although until now no specially designed plants have been built for the beneficiation of such ores. Generally the zinc carbonate and zinc silicate ores are hand picked and shipped to this country for beneficiation. The Mexican production of zinc ores has never been steady, because of economic factors such as bad transportation systems and lack of market for …

The Effect Of Temperature On Mine Rocks, James Wilson Snider Jan 1947

The Effect Of Temperature On Mine Rocks, James Wilson Snider

Masters Theses

"The problem of this investigation involves the determination of the coefficients of thermal expansion of mine rocks, and the relationship of porosity, permeability, and consecutive temperature changes to the permanent elongation of those rocks. One of the major problems in mining today is that of the analysis of the action of exposed mine rock under changes of temperature. The immediate cause of a fall of ground in a mining excavation is due to the fact that some part of the mass that falls has been subjected to a stress beyond the strength of the rock. The question arises as to …

The Effect Of Rope Speed And Moisture On Mine Scrapers, Ronald L. Carmichael Jan 1947

The Effect Of Rope Speed And Moisture On Mine Scrapers, Ronald L. Carmichael

Masters Theses

"During recent years the use of power drawn scrapers, sometimes called "slushing", for the transfer of ore and waste rock has become standard practice in many mining operations. Scraper types have been developed to meet various operating conditions by trial and error methods and by practical research. The study of scraper efficiency has been confined in the past mainly to power consumption. A detailed study of the effect of rope speed and moisture content of the material being moved on scraping efficiency, under controlled conditions, has not been noted in a review of the literature. The author feels that such …

A Comparative Study Of Dehydrating And Infiltrating Agents, Frieda Nankin Jan 1947

A Comparative Study Of Dehydrating And Infiltrating Agents, Frieda Nankin

Bachelors’ Theses

Because of the complex, innate structural differences in animal tissues, it is difficult to name any one reagent or method as universally superior for dehydration and infiltration in micro-technique. Certain reagents have proved superior in preparing particular tissues for micro-scopical study. However, caution must be used in making such claims.

The Revival Of The Folk Dance As Social Recreation In Northern California, Grace Tener Frye Jan 1947

The Revival Of The Folk Dance As Social Recreation In Northern California, Grace Tener Frye

University of the Pacific Theses and Dissertations

This paper is limited to a few brief but important statements on the early development of the folk dance. As for its origins, it is quite obscure. From the studies of its beginnings, it can be freely said that it began with primitive man who used his body to express his feelings. Ruth Radir writes; "Man, we believe, has always danced. The beginnings of the dance, like the beginnings of all man's expressive life, are shrouded in a speculative past."1

A Comparison Of The Use Of Polaroid And Colored Filters In The Multiplex Aeroprojector, Robert Greig Livingston Jan 1947

A Comparison Of The Use Of Polaroid And Colored Filters In The Multiplex Aeroprojector, Robert Greig Livingston

Masters Theses

"The purpose of this thesis is the drawing of a comparison between the use of the colored filters, which are normally employed in the multiplex aeroprojector by various mapping agencies throughout the country, and the use therein of Polaroid filters. The filters in the aeroprojector serve to break the projection of a stereoscopic pair of photographs into two impressions which are viewed separately by each eye of the observer, thus providing the main requirement for the observance of a three-dimensional effect. this stereoscopic effect is utilized in the multiplex plotting machine for the delineation of contours...In order to form a …

Geology Of The Einstein-Apex Tungsten Mine Area, Joel B. Pomerene

Masters Theses

"The geological problem existing in the Silver Mine area, the relationship of mineralization to structure, particularly to faulting and jointing, was pointed out to the writer by Prof. O. R. Grawe. Several geologists have made reconnaisance [sic] surveys of the whole region, but so far no detailed geologic map has been published of the immediate area. Prof. Grawe pointed out that such a map would be of value in the better understanding of the area and would be especially useful in the event that another national emergency required the development of all possible sources of tungsten"--Introduction, Selection of the Problem, …

An Investigation Of Various Properties Of The 60co-40cr Alloy, Roger David Moeller Jan 1947

An Investigation Of Various Properties Of The 60co-40cr Alloy, Roger David Moeller

Masters Theses

"The binary alloys of Co-Cr have had a few practical applications in our modern economy due to their high cost. The only extensive field of application has been developed in recent years in the manufacture of high temperature alloys for such equipment as gas turbines, jet engines, and turbo-superchargers. The use of these materials has been limited, due to their high cost, to small parts such as rotor blades in gas turbines. To reduce cost and to add desirable or eliminate undesirable properties, the binary alloys have, from the beginning, been modified with varying amounts of other metals. The modified …
