The Electrodeposition Of Chromium From Trivalent Salt Solutions, Bahri Ersoz
The Electrodeposition Of Chromium From Trivalent Salt Solutions, Bahri Ersoz
Bachelors Theses and Reports, 1928 - 1970
The enormous number of previous experiments and researches for the improvement of the commercial chromic acid bath, did not succeed even in the partial elimination of any one of the disadvantages of chromic acid bath. This led the author to believe that the poor performance is an inherent quality of the chromic acid bath, and is due to the fact that the deposition occurs from the higher state of oxidation.
Bright Electroplating Of Copper In The Acid Bath, Elwood K. Jensen
Bright Electroplating Of Copper In The Acid Bath, Elwood K. Jensen
Bachelors Theses and Reports, 1928 - 1970

The Effect Of Boron On The Hardenability Of Steel, William J. Foy
The Effect Of Boron On The Hardenability Of Steel, William J. Foy
Bachelors Theses and Reports, 1928 - 1970
Many attempts have been made to improve iron and steel and their alloys by the addition of boron. The results obtained were not encouraging for the reason that the amount of boron used, generally from 0.2 to 2.0 per cent is altogether too high. This percentage of boron renders the product hard and brittle and of late the experiments with boron in this connection have been practically abandoned.
An Attempt To Increase The Permeability And Porosity Of The Cut Bank Oil Sand By Treatment With Various Reagents, Donald H. Johnson
An Attempt To Increase The Permeability And Porosity Of The Cut Bank Oil Sand By Treatment With Various Reagents, Donald H. Johnson
Bachelors Theses and Reports, 1928 - 1970
The purpose of this investigation was to attempt to find some means of increasing the effective porosity and permeability of the producing sands of the Cut Bank Oil Field, with the hope that thereby the ultimate recovery of petroleum from this field may be increased. Although the percentage increase in production thus effected would undoubtedly be small, it would represent a substantial volume of petroleum in view of the great quantity of oil and gas present in this field.

Bachelors Theses and Reports, 1928 - 1970
At the present time ore bodies being mined are becoming more and more complex in mineral association, thus presenting a more difficult problem in their concentration. Lead-zinc sulphide ores are among the more common ores which present such difficulties.
Permeability And Porosity Studies Of The Cut Bank Oil Sand, Wesley Edward Davis
Permeability And Porosity Studies Of The Cut Bank Oil Sand, Wesley Edward Davis
Bachelors Theses and Reports, 1928 - 1970
In studying the Cut Bank field and its numerous wells, it is found that dry holes are surrounded by producing wells, and also that the field as a whole is very irregular; water, oil, and gas zones in many cases following no definite pattern. In some instances, this phenomenon may be due to the lensing and thinning of the producing sands, but it is evident that this is not the only factor. Therefore, the controlling factors must be porosity and permeability.
Coal In Montana, Clifford A. Barkell
Coal In Montana, Clifford A. Barkell
Bachelors Theses and Reports, 1928 - 1970
Coal was first mined in Montana in the year 1880. For the last thirty years the mining of coal in this state has been very important-with few people realizing its value. In the mineral industry, the value of the annual production of coal is exceeded by none of the non-metallics, and only by gold, silver, and copper in the metallics. At the present time the coal production of Montana is valued at about 41000,000.00 annually.

With the present war demands and the possibility of a future market it is essential that work expended to utilize this important mineral.
An Investigation Into The Recovery Of Indium From Fume Residue, Emery J. Turner
An Investigation Into The Recovery Of Indium From Fume Residue, Emery J. Turner
Bachelors Theses and Reports, 1928 - 1970
Several months were required to produce a single gram of indium. Consequently, the industrial history of the metal is extremely short. In view of the unique properties that indium has demonstrated in this short period, it is probable that indium is still in its early stage of development. However, the commercial applications of the metal are well established and indium is now produced on a commercial scale. It is obtainable as the metal or in solution for electroplating.

The Recovery Of Zinc From Butte Mine Waters, Edmond M. Fern
The Recovery Of Zinc From Butte Mine Waters, Edmond M. Fern
Bachelors Theses and Reports, 1928 - 1970
Very little work has been done towards the recovery of zinc from mine water because the zinc content of the water is generally low. As different from copper, which can very easily be replaced by iron in any of its solutions, zinc is very high up in the electro-chemical series and so the few metals above zinc, most of which are rare and hence expensive, cannot be used to replace zinc from its solution.
Mineralogy And Genesis Of The Vermiculite Deposits At Libby, Montana, Raymond Kujawa
Mineralogy And Genesis Of The Vermiculite Deposits At Libby, Montana, Raymond Kujawa
Bachelors Theses and Reports, 1928 - 1970
The problem considered in this report is one of the mineralogy and mode of formation of the extremely pure, large bodies of vermiculite. Mineralogically the ultrabasic intrusive, with which the economic mineral is associated, presents an array of rather unusual minerals. The determination of these minerals, their associations, and the sequence of alteration that lead to the formation of the vermiculite bodies, constitutes the problem.

Insoluble Residues Of The Lower Mississippian Limestones Of The Madison Group, Fred G. Lines
Insoluble Residues Of The Lower Mississippian Limestones Of The Madison Group, Fred G. Lines
Bachelors Theses and Reports, 1928 - 1970
The correlation of non-fossiliferous drill samples is one of the difficult problems that is encountered in sub-surface stratigraphy. In order to truly correlate a formation, it must have some dis tinctive features and have an areal persistence of these features. These requirements are probably met best by limestone.
Chromite Deposits Near Red Lodge And Silver Star, Montana, Edmond F. Smigel
Chromite Deposits Near Red Lodge And Silver Star, Montana, Edmond F. Smigel
Bachelors Theses and Reports, 1928 - 1970
The Red Lodge and Silver Star chromite deposits of Montana have stimulated much interest during periods of war. The Red Lodge deposit is 25 miles southwest of Red Lodge which is also the nearest railroad point. Several workings are scattered throughout the area, exposing lense-like ore bodies averaging 33% chrome oxide. Silver Star is a much smaller deposit 5 miles west of Silver Star, Montana, which is its nearest railroad point. Lenses of chromite are exposed by pits and trenches, which average approximately 36% chromic oxide.
