A Study Of Base Exchange And Attendant Disintegration In Carthage Marble, Elmond Lowell Claridge

Masters Theses

"The purpose of this investigation was to study the base exchange reaction occurring in Carthage marble as a possible cause of unusually rapid disintegration of Carthage marble which has been widely observed in various localities and under certain conditions. If this were found to be the principal cause of such disintegration the groundwork would be laid for research on a means of preventing it. According to Mr. R. E. Mayes, president of the Carthage Marble Corporation, forty to fifty percent of the stone quarried by this company is discarded because of large stylolitic veins. This represents a loss of many …

Manufacture Of Salt Cake By The Hargraeves Process, Philip Hall Delano

Masters Theses

"The Hargraeves process of manufacturing salt cake has not lived up to the great expectations that were held for the process at the time of its development...The inventors, Hargreaves and Robinson, do not pretend to have been the first to make salt cake by the action of sulfur dioxide upon common salt in the presence of air and steam; they claim only to have made the process practicable by a large number of patents. Numerous earlier patents for this reaction were taken out by others but none of these former proposals was successful; it was the details of the process …

Studies On The Quantitative Analysis Of Rhenium And Its Occurrence In The Products Of Molybdenite Processing, Walter Keith Dean

Masters Theses

"There is at the present time no commercially developed source of the metal rhenium in the United States. Since this metal is known to exist in molybdenite, it was felt that a study of the products of the metallurgical processing of this mineral might reveal a source of rhenium that could e developed. The Climax Molybdenum Co. provided a number of samples from their smelter at Langloth, Pennsylvania. Although an improved method for the quantitative estimation of rhenium was recently published, its accuracy was not high and the procedure exacting and time-consuming. These combined factors led to the selection of …

The Mineral Association In Manganese Ores, With Particular Reference To The Phosphorus-Bearing Minerals And Their Removal By Leaching Methods, Daniel Chalmers Mclean

Masters Theses

"The United States Bureau of Mines Experimental Station at Rolla has recently been conducting an intensive investigation of the amenability of Arkansas red ores to enrichment by standard ore dressing methods. These Arkansas ores are low grade with the estimated reserves running into several million tons. They can be concentrated to meet all Grade B ferromanganese specifications - with the exception of that of the phosphorus content, but in all cases the phosphorus is so high as to make the ore worthless under present conditions. This condition suggested the problem of trying to discover a method by which the phosphorus …

Conodonts From The Marathon Basin, Brewster County, Texas, Roy William Graves Jr.

Masters Theses

"Conodonts were discovered in the limestones of the Marathon region in the Big Bend country, Brewster County, Texas, as a result of field work during the summer of 1939. This was not the first known occurrence of these fossils from this region, however, as King earlier mentioned the occurrence of conodonts in siliceous shales of Devonian age. The discovery of conodonts in the Ordovician and Pennsylvanian limestones of the area had its inception in the attempt to determine whether the Dimple limestone (lower Pennsylvanian) or Maravillas limestone (upper Ordovician) was involved in a fault that was being mapped. These limestones …

Electrodeposition Of Copper-Lead Alloys From A 7.2 Per Cent Amine Solution Saturated With Respect To Copper And Lead. Study Of The Production Of Cupric Oxide To Be Used As Solute, Edmund Simon Roszkowski

Masters Theses

"The purpose of this work is to deposit electrolytically a copper-lead alloy from an amine solution for use specifically as a bearing metal. Generally speaking there are four classes of bearing metals: tin base alloys or the babbitts; the cadmium base alloys or the white metals; the silver alloys; and the copper-lead alloys. Additions of other metals may be employed to produce alloys with certain desirable properties"--Introduction, page 1.

The Electrolytic Separation Of Copper, Nickel And Precious Metals From Copper-Nickel Matte, Oden Cass Garst

Professional Degree Theses

"During the last few years considerable interest has been shown in domestic reserves of strategic metals. Broadly speaking, the strategic materials of any nation are those materials of commerce essential to the country both in time of war and peace, which are not produced within the boundaries of that country in sufficient quantities to supply even peace-time requirements. The United States is far more fortunate than other countries inasmuch as there are only eight metals which may be classified as being strategic metals; namely, aluminum, antimony, chromium, manganese, nickel, mercury, tin, and tungsten. The work on nickel covered herein was …

Coal Mine Safety Engineering, Charles F. Herbert

Professional Degree Theses

"The progress of coal mine safety may be compared to the development in mining through the years. When coal was first discovered centuries ago, it was taken from river or creek beds and from the outcroppings on the sides of hills. After removing the most accessible coal from the surface, it was necessary to mine the coal by quarrying or stripping the overburden from the coal seams. It is reasonable to assume that when such operations began, accidents of a serious nature also began to occur. Such accidents were no doubt due to rolling rocks or stones, falling material, and …

The Chemical Engineering Aspects Of The Saint Louis Smoke Problem, George Augustus Hale

Professional Degree Theses

"During past years smokeless combustion of fuels has been conscientiously sought only in those larger industrial plants where fuel costs were a major factor. Smoke was considered a sign of prosperity in some moderate and even large size industrial practice, and no wholehearted effort was made to utilize the vast amount of energy lost through the smoke stack in the form of unoxidized carbon.

Inefficient combustion, which is so common today, is due in part to a wrong approach to the study of this problem. Industrial combustion, as a science, has, to a certain extent, been left to the mechanical …

Some Causes For Porosity And Leakage In Non-Ferrous Castings, Alfred H. Hesse

Professional Degree Theses

"Non-ferrous copper base alloys find many applications in industry. Among these alloys one finds the tin bronzes rather widely used for many purposes, and by delving still farther one finds pressure castings as one of their important applications. In many foundries the percentage of rejections due to leakage or porosity is quite high. This is obviously very costly since leakage is generally only found after machining. It is with a view to determine the causes for leakage in pressure castings and to devise methods for its prevention that the work described in this thesis was undertaken. It is not intended …

The Scope Of Functions Delegated To The Engineering Department Of A Typical, Progressive Metal Mine, Alvin William Knoerr

Professional Degree Theses

"Nearly every conscientious engineering student will subject his college courses to an occasional critical analysis in an effort to assure himself that the studies he is pursuing will be a valuable aid to him in future practice. Possibly this skeptical attitude is accentuated by published letters of graduate mining engineers who decry the courses of mining schools in general and clamor for more practicability and higher specialization. Pure science as it is taught may at times seem to be very remote from any possible practical application. Mathematics may appear to be highly abstract. It seems quite logical that the degree …

Dewatering & Rehabilitating The Oronogo-Webb City Mining Area, Robert Knox Stroup

Professional Degree Theses

"The object of this paper is to describe the dewatering of the Oronogo-Webb City mining area, and the subsequent mining operations which were carried on in the northern section of that area. It deals with the development in that district during the time the writer was familiar with operations there; i.e., from 1935 to 1939, inclusive, and no attempt is made to describe the open pit mining and local milling which have been carried out as a latter part of this same project. Also, no attempt is made to describe the surface drainage work which was planned and carried out …

History of the University

The Phelps County Historical Society was organized on August 26, 1938, for the purpose of collecting, preserving, organizing, and publishing in legible and available form the rich historical materials that relate to the people and the institutions of Phelps County, Missouri, and the immediately surrounding territory.

Missouri School of Mines and Metallurgy -- sometimes called the “Rolla School of Mines” -- is a world-famed scientific and engineering school that has grown up within the borders of Phelps County. It is not in any sense a local institution, but was established in 1870 and has since been maintained jointly by the …

The Effect Of Glaze Fit Upon The Strength Of Missouri Zadock, Karl Emil Krill, Floyd Rolland Elliott

Bachelors Theses

"We know that, in the case of a beam, the really effective part of the cross-sectional area is that part farthest from the neutral axis. The I-beam, with most of the central area eliminated, is just as strong as is the rectangular beam of similar outside dimensions. Why should not the glaze on a piece of ceramic ware play as important a part in the strength of the piece as does the outermost area in a beam? Microscopic cracks in the flanges of an I-beam weaken it appreciably. Might not a parallel case exist in a piece of glazed pottery …
