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. ­

The Scope Of Functions Delegated To The Engineering Department Of A Typical, Progressive Metal Mine, Alvin William Knoerr

Professional Degree Theses

"Nearly every conscientious engineering student will subject his college courses to an occasional critical analysis in an effort to assure himself that the studies he is pursuing will be a valuable aid to him in future practice. Possibly this skeptical attitude is accentuated by published letters of graduate mining engineers who decry the courses of mining schools in general and clamor for more practicability and higher specialization. Pure science as it is taught may at times seem to be very remote from any possible practical application. Mathematics may appear to be highly abstract. It seems quite logical that the degree …

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.

The Mineral Association In Manganese Ores, With Particular Reference To The Phosphorus-Bearing Minerals And Their Removal By Leaching Methods, Daniel Chalmers Mclean

Masters Theses

"The United States Bureau of Mines Experimental Station at Rolla has recently been conducting an intensive investigation of the amenability of Arkansas red ores to enrichment by standard ore dressing methods. These Arkansas ores are low grade with the estimated reserves running into several million tons. They can be concentrated to meet all Grade B ferromanganese specifications - with the exception of that of the phosphorus content, but in all cases the phosphorus is so high as to make the ore worthless under present conditions. This condition suggested the problem of trying to discover a method by which the phosphorus …

Bachelors Theses and Reports, 1928 - 1970

This trip was conducted to give those students working for their respective degrees an excellent opportunity to work under actual field conditions. A total of three weeks was taken to complete the required work. Two weeks were spent in the field gathering data, and making maps, and the last week was spent in the drawing room at the college preparing the final map.

The Age-Hardening Of Aluminum With Mgzn2, Sidney E. Worthen

Bachelors Theses and Reports, 1928 - 1970

The purpose of this thesis is to investigate the age-hardening of aluminum with magnesium and zinc in such proportions as to conform to the compound MgZn₂.

Because of a lack of time and proper equipment, the only property investigated was the hardness as indicated by the Rockwell Superficial Hardness Tester.

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.

The Measurement Of Current Efficiency In Zinc Sulphate Electrolytes Containing Antimony And Cobalt By Hydrogen Evolution, Arthur R. Hard

Bachelors Theses and Reports, 1928 - 1970

The measurement of current efficiency by hydrogen evolution is based on the assumption that the portion of the current which deposits no zinc will release hydrogen. This assumption is correct for solutions containing no impurities electropositive to zinc.

The Geology And Mineralogy Of The Independence Mining District, Alan Kuhlman

Bachelors Theses and Reports, 1928 - 1970

From 1888 until 1893 the district was a booming mining camp. Seven stamp mills were running and ore was be­ing mined from the Independence, King Solomon, Poorman, Golden, Hidden Treasure and Crown claims. The town of Independence, which was on the Boulder River at the fork of Basin Creek, boasted a population of 400 people.

A Study Of Metallic Eutectics, Robert P. Corbett

Bachelors Theses and Reports, 1928 - 1970

All of the metals have definite melting points. When a metal is heated above the melting point, it exists as a liquid. Now if the melt is allowed to cool, it will solidify when a temperature corresponding to the melting point is reached.

However, if one metal is added to another metal, both of which are mutually soluble in the liquid state, a certain effect can be noted. The melt will not solid­ify when the melting point of the pure metal is reached, but will freeze at a lower temperature.

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.

A Study Of The Concentration Of A Copper-Zinc Ore., Kenneth L. M. Dodd

Bachelors Theses and Reports, 1928 - 1970

The ore under investigation in this thesis is a copper-zinc ore which came from the state of New Mexico. The exact location is unobtainable. The purpose of the investigation was to determine the most effective means of concentration of the valuable min­erals present in the ore.
