The Testing And Concentration Of Lake Chelan Copper Ore, Thor W. Johnson May 1941

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.


Pegmatites In Southwestern Montana, Ora Rostad May 1941

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 May 1941

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. ­

Electrodeposition Of Copper-Lead Alloys From A 7.2 Per Cent Amine Solution Saturated With Respect To Copper And Lead. Study Of The Production Of Cupric Oxide To Be Used As Solute, Edmund Simon Roszkowski Jan 1941

Electrodeposition Of Copper-Lead Alloys From A 7.2 Per Cent Amine Solution Saturated With Respect To Copper And Lead. Study Of The Production Of Cupric Oxide To Be Used As Solute, Edmund Simon Roszkowski

Masters Theses

"The purpose of this work is to deposit electrolytically a copper-lead alloy from an amine solution for use specifically as a bearing metal. Generally speaking there are four classes of bearing metals: tin base alloys or the babbitts; the cadmium base alloys or the white metals; the silver alloys; and the copper-lead alloys. Additions of other metals may be employed to produce alloys with certain desirable properties"--Introduction, page 1.


Some Causes For Porosity And Leakage In Non-Ferrous Castings, Alfred H. Hesse Jan 1941

Some Causes For Porosity And Leakage In Non-Ferrous Castings, Alfred H. Hesse

Professional Degree Theses

"Non-ferrous copper base alloys find many applications in industry. Among these alloys one finds the tin bronzes rather widely used for many purposes, and by delving still farther one finds pressure castings as one of their important applications. In many foundries the percentage of rejections due to leakage or porosity is quite high. This is obviously very costly since leakage is generally only found after machining. It is with a view to determine the causes for leakage in pressure castings and to devise methods for its prevention that the work described in this thesis was undertaken. It is not intended …


Dry Pressing Refractory Insulating Brick, Frank Clarence Steimke Jan 1941

Dry Pressing Refractory Insulating Brick, Frank Clarence Steimke

Bachelors Theses

"The expensive process of grinding the insulating brick and the slow production methods of hand forming led to the possibilities of dry pressing the brick. The use of the dry press would increase production, give greater uniformity to the brick and materially reduce grinding if not eliminating it entirely. Since present day combustives were either impractical or else impossible to use, some new material must be found. Three materials presented themselves, napthalene, sulfur, and petroleum coke. The former for its low melting temperature and the latter two for their complete volatility at high temperatures and low if not negligible resiliency. …

The Investigation Of Different Variables In The Assaying Of Silver Cyanide Solution, Warren M. Mahan May 1940

The Investigation Of Different Variables In The Assaying Of Silver Cyanide Solution, Warren M. Mahan

Bachelors Theses and Reports, 1928 - 1970

The assaying of gold and silver cyanide solutions is by no means new. The first method of analysis which is given in the literature is an evaporation method by S. B. Christy in 1896. However, the fire assaying of gold and silver dates further back than this. There is a method of fire assaying for gold and silver given in literature as early as 1556 in Georgius, Agricola’s De Re Metallica book.


Areal Geology Of The Post-Paleozoic Surface Of The Northwest Plains, William M. Broderick May 1940

Areal Geology Of The Post-Paleozoic Surface Of The Northwest Plains, William M. Broderick

Bachelors Theses and Reports, 1928 - 1970

Probably most of the area included in this report has been ex­amined to some extent by oil geologists, and most, if not all, of the important domes have been discovered and surveyed thoroughly. In parts of the area, the bedrock is covered by glacial drift or alluvium materi­al, but it is reasonable to believe that no new domal structure will be found. This means that surface examination alone will be insufficient in locating new oil fields, so future prospecting will be dependent, to a great extent, on studies of sub-surface stratigraphy.


The Testing And Concentration Of A Low Grade Copper-Nickel Ore., Laurence T. Eck May 1940

The Testing And Concentration Of A Low Grade Copper-Nickel Ore., Laurence T. Eck

Bachelors Theses and Reports, 1928 - 1970

The purpose of this thesis is to investigate the possi­bility of concentrating a low grade copper-nickel ore, to determine the most effective method of concentration, and to attempt to draw some conclusions to determine whether or not the concentrates produced would be of sufficient high grade to make the recovery of nickel and copper a profit­able enterprise.

Constitution And Properties Of Manganese-Copper Alloys, James Harrison Jacobs Jan 1940

Constitution And Properties Of Manganese-Copper Alloys, James Harrison Jacobs

Masters Theses

"This work was undertaken because of the recently revived interest in the use of manganese as an alloying element. This revival of interest has been mainly due to the development of the process for electro-deposition of manganese by the U. S. Bureau of Mines. Prior to the work of the bureau of Mines there was no commercial source of high purity manganese. Manganese made by the electrolytic process contains less than .03% impurities, while manganese made by other methods contains as high as 3% impurities. The use of high purity manganese as a base for alloys should open up an …


Firing Behavior Tests And Other Tests On A Missouri Stoneware Clay To Determine Its Commercial Possibilities, Ivan Martin Niedling Jan 1940

Firing Behavior Tests And Other Tests On A Missouri Stoneware Clay To Determine Its Commercial Possibilities, Ivan Martin Niedling

Bachelors Theses

"A clay's essential character is its plasticity, whether it is to be used for common brick purposes, the manufacture of refractory articles, or merely as a bonding agent for nonplastic materials. Plasticity is a very large subject; there are many theories as to its cause and many methods have been developed to record it, but so far no satisfactory quantitative measure of plasticity has been found. Perhaps the most satisfactory method is to judge by handling the clay, and with constant practice one can become expert in judging the plasticity of a clay by its feel. Such a method is, …


X-Ray Data Concerning Some Manganese-Copper Alloys, George Lester Mitsch Jan 1940

X-Ray Data Concerning Some Manganese-Copper Alloys, George Lester Mitsch

Bachelors Theses

"Until recently the only commercial method of producing metallic manganese in large ammounts sic was a pyrometallurgical process. Producing a metal of about 97% purity, it was not very satisfactory. With the advent of a process for producing a metal of 99.9 plus % purity electrolytically, introduced by the United States Bureau of Mines, for the first time was there a sufficient quantity of pure manganese available for alloy use. The manganese-copper system was chosen for study because of the inconsistencies in the reports of previous investigators, and because of the properties alloys of these components possess, such as magnetism, …

Fifty Years Of Achievement In Agricultural Investigation, R. T. Prescott Mar 1939

Fifty Years Of Achievement In Agricultural Investigation, R. T. Prescott

Nebraska Agricultural Experiment Station: Historical Circulars

In Nebraska, a hustling frontier state in 1887, the legislature hesitated not at all in taking advantage of the provisions of the Hatch Act, and now that fifty years have elapsed since the Station was founded, seventy-five years since the Land Grant College Act was passed and the U. S. Department of Agriculture established, and almost twenty-five years since the Agricultural Extension Service was added, it seems worth while to present a general summary of achievement within the state. The main object will be to show some of the important things that have been learned through the investigations of the …
