The Relation Of The Composition Of A Mineral To Its Properties, Edwin Phelps Murray

Professional Degree Theses

"The attempt has been made to bring together and to classify the properties of minerals and to show that there is some simple qualitative relation between their composition and physical properties, or in other words, to show that minerals containing different percentages of a certain element will all have similar properties dependent upon the proportion of that element. Further investigation of this subject would be in determining the modifying influence of crystal form"--page 1.

Minerals And Their Environment Of Formation, Deforrest Don

Bachelors Theses

"The history of mineralogy began with the development of mining and the use of certain minerals as useful products, such as lime, pigments and precious stones. In order to know how to distinguish these minerals when found and where they were likely to found, it was necessary to study the nature, properties and the modes of occurrence. In order to determine all these properties, it was necessary to classify and compare them with the purpose of ascertaining how they resemble each other, and how they differ"--page 1.

Design Of Reinforced Concrete Water Tower And Tank, Harvey Oden Garst, Pearl Frederick Michael

Bachelors Theses

"Theoretically the most economical dimension for a flat bottomed cylindrical tank would be such that the height of the tank is equal to the diameter, but such a tank does not look as well as one which has the height a little greater than the diameter and as the cost will be affected but little by making the height a few feet greater than the diameter, the most economical design will not be strictly carried out in this particular"--Data, page 1.

Pot Roasting Of Lead Ores, Ralph Robert Benedict, Edward Phillip Barrett, Frank William Harper

Bachelors Theses

"In this thesis for a starting point, we attempted a roast of straight galena with no diluent. As anticipated the results were nil. We next attempted the roast with a mixture of galena and silica, and obtained fair results. Our next experiment was to use limestone with the galena. Because of the large percentage of limestone present the results were not satisfactory. Next pyrites and limestone were used with the galena, and excellent results were obtained. We made another run, using pyrites and limestone, but increasing the per-centage of galena by 25%. This run was also very successful. From these …

Square Set System Of Timbering As Employed By The Shannon Copper Co., Ray Eugene Hoffman

Professional Degree Theses

"The properties of The Shannon Copper Co., consisting of mine and smelter, are located in the Southeastern part of Arizona in what is known as the Clifton-Morenci District. The smelter is located at Clifton and the mine at Metcalf, eight miles distant on an iron capped mountain known as Serro Preito.

From a geological standpoint the ore deposits of the Clifton-Morenci District are a freak. There are no fissure veins of any consequence in the district; all the large deposits are found in bodies, the ore usually occurring in a soft porphyry.

Underlying the iron capping on the Shannon property …

Effect Of Arsenic On Assay For Gold And Silver, Rosco Conkling Ham, Frederick Arnold Moore

Bachelors Theses

"In presenting the within thesis, it is not claimed by the authors that the experiments have been, by any means, exhaustive of the subject. Neither is any claim made to original research work other than a series of simple experiments with a view to determining, if possible, some of the more important effects of Arsenic upon a fire assay for gold and silver as met with in the ordinary assay laboratory. To make a work complete and exhaustive on such a subject will require much more time and more complete apparatus than was available in the experiments covered by this …
