Some Preliminary Investiagtions Of The Magnetic Permeabilities Of Alloys Of The Ferromagnetic Metals, John H. Gambill Jr.

Bachelors Theses and Reports, 1928 - 1970

The problem presented for this thesis was an investigation of the magnetic properties of the alloys produced by the methods of powder metallurgy. The question behind this was the correlation of the magnetic properties with the bonding properties and with the diffusion of the constituents.

The Theory Of Alloy Deposition And The Effect Of A Rotating Cathode Upon Such Deposition, With Special Attention To The Possibility Of Depositing Sterling Silver, Kenneth J. Stodden

Bachelors Theses and Reports, 1928 - 1970

In the past few years a great deal of atten­tion has been given to the electrodeposition of alloys. For the main part, this investigation has been of scien­tific interest only; but in a few instances, such work has attained commercial importance.

Measurements Of The Magnetic Permeabilities Of The Iron-Manganese Alloy System Prepared By The Methods Of Powder Metallurgy, O. Cihad Onbulak

Bachelors Theses and Reports, 1928 - 1970

Powder metallurgy is a branch of metallurgy which produces metallic compacts in their final forms by means of pressure and heat-treatment from the pow­ders. The products of powder metallurgy are being used in our daily lives quite often. For example, the tungsten wires in the electric bulbs to the silver-tin fillings of our teeth.

The Extraction Of Chromate Salts From Montana Chromite, Server Tasdemiroglu

Bachelors Theses and Reports, 1928 - 1970

In this thesis I have tried to determine the suit­able temperature, time and the amount of soda ash and lime needed for the calcining process. The leaching and purification tests were studied experimentally. The earlier process for making chromate from chromite was not the same as is used today. There­fore I have found it useful to put into this thesis the newest method for making chromate salts and their important uses.

An Experimental Investigation Of The Age Hardening Of Copper With Manganese Silicide, Ali Kozak

Bachelors Theses and Reports, 1928 - 1970

The subject of the thesis was based upon the theory of precipitation or age hardening of the copper by the compound formed by the Manganese and silicon present in the ternary Cu-Mn-Si alloy. The effect of the heat treat­ment to such an alloy was to be studied and the best aging time and temperature was to be determined.

The Electroformation Of Lithium-Lead Alloys From Molten Electrolytes, Thomas Prater

Bachelors Theses and Reports, 1928 - 1970

An attempt was made to make lead-lithium alloys by electrodeposition of lithium using a molten bath and a molten lead cathode.The variables taken into consideration were: composition of the melt, temperature of the melt, and current density. The purpose of changing these factors was to determine what effect each had on the current efficiency.

Ground Water In The Lake Basin Field And Adjacent Area, Herman Neibauer

Bachelors Theses and Reports, 1928 - 1970

Oil And Gas Production Methods In Montana, Edgar A. Scholz

Bachelors Theses and Reports, 1928 - 1970

Montana's oil and gas industries aggregate a gross income of over 12,000,000 annually to the state. Oil and gas fields have been thoroughly discussed in liter­ature as to geology, location, production and future possibilities. The specific object of this report has been to compile a comprehensive study of the production methods as they occur.

The Geology And Ore Deposits Of The Ermont Mines, James L. Kelly

Bachelors Theses and Reports, 1928 - 1970

The Ermont Mines are located sixteen miles northwest of Dillon, Montana, in section 35 of T.6S., R.11W. This is in the central part of Beaverhead County. They are considered to be in the Argenta min­ing district, the town of Argenta lying three miles to the northeast.

The Concentration Of Scheelite From The Gold Concentrates Of The Jardine Mining Company, John H. Huxley

Bachelors Theses and Reports, 1928 - 1970

The Purpose of this thesis was to investigate the possibility of concentrating scheelite from Wilfley table gold concentrates from the mill of the Jardine Mining Company; and to determine whether such concentration is economically feasible and the product of sufficiently high grade to meet commercial specifications for such a product.

The Testing And Concentration Of Lake Chelan Copper Ore, Thor W. Johnson

Bachelors Theses and Reports, 1928 - 1970

The geologic history of the Holden area and Lake Chelan district is an integral part of the history of the Cascade Mountain Range. The structure is very complex and the rocks, which have been subjected to intense metamorphic action, are portions of a roof pendant and consists of gneisses, schists and quartzites that are often difficult to correlate.

Gas Analysis By Absorption, Albert D. Mcmahon

Bachelors Theses and Reports, 1928 - 1970

There is practically only one method of gas analysis. This was worked out many years ago by Bunsen, Hempel, and Winkler and consists in the successive absorption with different chemicals of the various constituents of the gas. The only improvement to this method is the oxidation and combustion of different components of a mixture followed by absorption.

Relationships Of Manganese Minerals In The Butte District, Charles F. Parent

Bachelors Theses and Reports, 1928 - 1970

The use of manganese in the steel industry as a deoxidizing and desulfidizing agent makes it a necessity in modern industry, while the various alloy steels using manganese for the quality of toughness are also indispensable. Manganese is also used in the manufacture of such various articles as battery cells, paints and glass.

Pegmatites In Southwestern Montana, Ora Rostad

Bachelors Theses and Reports, 1928 - 1970

Little has been written on pegmatites in Montana except in conjunction with reports on mining districts. This subject was chosen as a senior thesis to see what facts could be ascertained re­garding pegmatites alone, and an attempt has been made by the writer to assemble all written material on pegmatites in southwestern Montana, and to study specimens from those that could be reached or from which specimens were available.

A Study Of The Concentration Of A Low-Grade Manganese Ore From The Ennis District, John B. Schuettenhelm

Bachelors Theses and Reports, 1928 - 1970

The purpose of the investigation was to determine the most effective means of concentrating the manganese in the ore. The study was that of identification of the minerals present. This showed the presence of oxides of manganese and iron, and carbonates of calcium and manganese. Methods of investigation were planned to determined whether the ore could be concentrated effectively by gravity concentration methods. ­

A Study Of A Carbonaceous Gold Ore, James S. Huckaba

Bachelors Theses and Reports, 1928 - 1970

The presence of graphite in the ore of the Missouri-McKee Mine has made its treatment by the methods now used quite unsatisfactory. The study was undertaken to de­velop a new flow sheet which would give a high recovery and yet be economical enough to handle low grade material.

A Study Of Base Exchange And Attendant Disintegration In Carthage Marble, Elmond Lowell Claridge

Masters Theses

"The purpose of this investigation was to study the base exchange reaction occurring in Carthage marble as a possible cause of unusually rapid disintegration of Carthage marble which has been widely observed in various localities and under certain conditions. If this were found to be the principal cause of such disintegration the groundwork would be laid for research on a means of preventing it. According to Mr. R. E. Mayes, president of the Carthage Marble Corporation, forty to fifty percent of the stone quarried by this company is discarded because of large stylolitic veins. This represents a loss of many …
