Montana Oil Fields, Conrad F. Lundgren Jul 1939

Montana Oil Fields, Conrad F. Lundgren

Bachelors Theses and Reports, 1928 - 1970

Since the discovery of oil in Montana in1916, the petroleum industry has advanced to a point where over 5,000,000 barrels of oil worthover $6,500,000 has been produced in each of the three past years (1936, 1937, and 1938).


The Age Hardening Of Silver With Copper-Silicide, Joseph Edward Shaw May 1939

The Age Hardening Of Silver With Copper-Silicide, Joseph Edward Shaw

Bachelors Theses and Reports, 1928 - 1970

The successful application of the phenomenon of pre­cipitation hardening to aluminum and copper has indicated the possibility of hardening all metals in the same way. The phenomenon of age hardening was discoveredin 1911, and since that time much research has been car­ried on in all parts of the world on various alloy sys­tems.


Structure Of Eutectics, Dilip K. Das May 1939

Structure Of Eutectics, Dilip K. Das

Bachelors Theses and Reports, 1928 - 1970

The present paper is a result of work done on the study of structures of eutectics of a certain eutectic-forming binary systems. In this research work no systems with intermetallic compounds have been studied.


Investigation Of A Method For Extraction Of Indium From Zinc Flue Dust., Harold L. Tanner May 1939

Investigation Of A Method For Extraction Of Indium From Zinc Flue Dust., Harold L. Tanner

Bachelors Theses and Reports, 1928 - 1970

In metallurgical practice today some of the relatively rare metal Indium is recovered as a by-product from the ores of other metals. Indium is a soft, silvery—white metal belonging to the third group of the periodic classification. It is situated just above tin in the electrochemical series.


Igneous Rocks Of The Jardine And Crevasse Mountain Mining Districts., Ray E. Gilbert May 1939

Igneous Rocks Of The Jardine And Crevasse Mountain Mining Districts., Ray E. Gilbert

Bachelors Theses and Reports, 1928 - 1970

It is surprising to learn that so large a variety of igneous rocks is present in the Jardine and Crevasse Mountain mining districts, a region that is generally thought of as consisting principally of schists.


The Age Hardening Of Copper With Manganese Silicide., Gordon A. Davis May 1939

The Age Hardening Of Copper With Manganese Silicide., Gordon A. Davis

Bachelors Theses and Reports, 1928 - 1970

The increase in hardness is attributed to the manganese silicide being precipitated from solid solution and deposited between crystal planes. The subsequent softening which occurs on prolonging the period of reheating is believed to be due to an agglomeration of the dispersed hardening agent.


Electrolytic Manganese, George T. Derana May 1939

Electrolytic Manganese, George T. Derana

Bachelors Theses and Reports, 1928 - 1970

The production of metallic manganese by electrolysis is of potential value for the recovery of this strategic metal from domestic deposits. These deposits are largely unsuitable for the production of ferromanganese, but they are amenable to low-cost leaching processes.


The Pre-Jurassic Surface Of Montana., G. Fay May 1939

The Pre-Jurassic Surface Of Montana., G. Fay

Bachelors Theses and Reports, 1928 - 1970

It has long been known that, prior to the deposition of Jurassic sediments, Montana was subjected to an intensive period of erosion. Mention of this may be found in numerous reports, especially those dealing with western Montana.


Powder Metallurgy, Cecil R. Waldron May 1939

Powder Metallurgy, Cecil R. Waldron

Bachelors Theses and Reports, 1928 - 1970

The metal powders may be produced in a number of different ways. In metals where the intercrystalline material is brittle enough, they may be ground in a ball mill or eddy mill. The fineness of such a powder is more or less controlled by the grain size of the original metal.


Geology Of The Golden Sunlight Mine And Vicinity, Roy H. Earhart May 1939

Geology Of The Golden Sunlight Mine And Vicinity, Roy H. Earhart

Bachelors Theses and Reports, 1928 - 1970

The Golden Sunlight Mine is in the northern part of the Cardwell mining district on the eastern slope of a small range that rises by a series of benches to an elevation of 7,200 at a point five miles east of the town of Whitehall in Jefferson County.


A Study Of Solders, John D. Prater May 1939

A Study Of Solders, John D. Prater

Bachelors Theses and Reports, 1928 - 1970

The purpose of this paper is to furnish a qualitative method of comparing the degree of wetting of various solders upon different plate metals when several fluxes are used.


Geology Of A Portion Of The Bull Mountain Range Jefferson County, Montana, Thomas A. Greene Jan 1939

Geology Of A Portion Of The Bull Mountain Range Jefferson County, Montana, Thomas A. Greene

Bachelors Theses and Reports, 1928 - 1970

Work was first done on a known section, the south Boulder Section, in order to familiarize the student with the formations. Most of the area was mapped by plane table and telescopic alidade, general features being surveyed by automobile traverse and a pacing traverse.


A Report Of The Geology Of The Golden Sunlight Mining District, Roy A. Mccready Jan 1939

A Report Of The Geology Of The Golden Sunlight Mining District, Roy A. Mccready

Bachelors Theses and Reports, 1928 - 1970

This paper is a report of a geological survey made of an area of approximately fifty square miles lying Northeast of Whitehall, Montana, in the region of the Golden Sun­light Mine. The survey was made by a field party consisting of twenty-three members of the senior class of the Montana School of Mines.


South Moccasin Kaolin Deposit, Walter Everly Jan 1939

South Moccasin Kaolin Deposit, Walter Everly

Bachelors Theses and Reports, 1928 - 1970

Kaolin has never been considered an important economic mineral in Montana. Deposits of Kaolin in this state are not described in the literature and apparently very few deposits have been found.
