Further, the work of Richards was restricted to quartz and galena whereas this study also includes pyrite and calcite.

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.

Polishing Mineral Specimens By The Use Of An Optical Polishing Machine, Wilbur J. Guay

Bachelors Theses and Reports, 1928 - 1970

The problem in this investigation was to determine if mineral specimens mounted in bakelite, or lucite, could be polished for microscopic examination by the use of an optical polishing machine, and if this method would cut down the length of time required to polish specimens by the methods now in use.

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

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.

Sizing By Elutriation Of Finely Ground Quartz And Pyrite, Elmer C. Polson

Bachelors Theses and Reports, 1928 - 1970

Elutriation, as a means of sorting mineral particles, has received marked attention during the last fifteen years. Its use in the ceramics industry for the sorting of clays was recognized even before this.

Preparation And Properties Of Diethylene Glycol Fumarate Resin, Marian Sargent

Bachelors’ Theses

The Influence Of Gelatin On The Ph Of Acids And Bases, Beverly Terwilliger

Bachelors’ Theses

The purpose of this thesis is to determine how gelatin behaves in the presence of various acids and alkalis. It is possible to titrate gelatins with acids and bases and thereby determine the relation of the pH of the solution to the amounts of acid or base combined with the gelatin. If the results are plotted, a titration curve is obtained, the value of which gives the acid and base combining properties of a certain gelatin.

A Chromium Plating Bath Containing Sodium Benzenesulfonate Instead Of Sulfuric Acid, Edward Burleigh

Bachelors’ Theses

At the present day chromium plated articles are saving the country many tons of badly needed metals. The beautiful, bright,luster that chromium has is no longer the prime quality that makes its use so extensive. Today its extreme hardness has taken the foremost place. Parts worn by use and re-claimed with chromium, not only wear longer than the original ones· but they also save valuable metal and time put into new ones. New articles plated with chromium have increased life, and thus the time and metal needed for replacement is greatly reduced.

The present chromium plating baths containing sulfuric acid …

The Cleaning Action Of Detergents And Soaps On Printer's Ink And Lubricating Oils, Daniel David Holzman

Bachelors’ Theses

During the past few years, industry has developed a steadily increasing interest in certain new types of synthetic organic compounds.

Industry devoted to the cleaning of textiles has found the removal of printer's ink and lubricating oils a tedious operation.

There has been developed and perfected a series of synthetic materials which successfully meet modern needs.

The detergents, in general, have some or all of the following properties: wetting-out, dispersing, emulsifying, penetrating, and cleaning.

There seems to be a need to investigate some of these new detergents for commercial cleaning purposes.

Phosphate Deposits In Western Summit, Wasatch, Salt Lake, Morgan, And Weber Counties, Utah, Alvin M. Hanson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Phosphate deposits in the western United States have been the subject of considerable discussion in the last decade, and during the last few years much interest has been aroused in them. Phosphate was first discovered in this area in 1889, but it was not until 1906 that the United States Government took active interest in the study of these deposits. The investigation by the government of the occurrence of western phosphate was begun by Weeks and Ferrier (10), and later carried on by others. On December 9, 1908 the western phosphate reserve was created and many acres of land were …

A Study Of The Electrolytic Reduction Of Pyrrole, Don Richard Strehlau

Masters Theses

"A review of the chemical literature has shown that electro-organic methods compare favorably with purely chemical methods for certain syntheses belonging to the following general classes of reactions: coupling, oxidation, reactions with halogens, and reductions. Electro-organic methods have been used most successfully in synthesis by reduction. The chief advantage is using electrolytic reduction in preference to a chemical one is that it offers a more exact control of conditions, and consequently should give a higher yield and a purer product. The advantages of the means of reduction suggested an investigation of its use in the synthesis of hydrogenated products of …
