The Velocity Of Falling Particles In A Liquid Medium, Elliott Coldwater
Bachelors Theses and Reports, 1928 - 1970
The investigation was prompted by the fact that there seemed to be some discrepancy between the results published by Richards,and the empirical figures used in classification and in gravity concentration. Further, the work of Richards was restricted to quartz and galena whereas this study also includes pyrite and calcite.

An Experimental Investigation Of The Age Hardening Of Nickel With Boron, Willard M. Boam
Bachelors Theses and Reports, 1928 - 1970
Since 1911, at which time, the age hardening phenomenon of duralumin was discovered by Film, much research has been carried on investigating the various alloy systems. The successful application of age hardening to the copper aluminum system (duralumin) has indicated the possibility of hardening practically all the metals in the same way.
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.

Porosity And Oil Absorption Properties Of Metal Compacts Of Copper - Tin - Graphite, Benjamin F. Mills
Bachelors Theses and Reports, 1928 - 1970
Powder metallurgy, the most recent innovation in metallurgical process, is not a new art; although not until recently did it become a matter of general interest, this being due not only to the products formed but also to the possibilities of future developments. The manufacture and application of metal powders is now beginning to take a position as a recognized part of the science of metallurgy.
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.

Bachelors Theses and Reports, 1928 - 1970
With the increasing importance of manganese in the metallurgical fields of today and tomorrow, extensive work along the lines of its successful exploitation has been accomplished by many investigators. Since tie current world situation has shut off most of our supply of high-grade manganese ores from foreign sources, the low-grade domestic deposits have entered the fields of investigation very rapidly.

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.
