The Electro Deposition Of Lead In Sugar And Acetate Solutions, Abe Lew Kaplan

Bachelors Theses

"The experiments, while hardly sufficiently numerous, seemed to indicate that sugars do not have a good effect on cathodic lead deposits"--Conclusion, page 14.

The Electrolysis Of Potassium Lead Tartrate Solutions, Reginald Scott Dean

Bachelors Theses

"Kahlenberg and Hillyer have shown that lead oxide (PbO) dissolves in neutral potassium tartrate to form a strongly alkaline solution in which the ratio of potassium to lead is 1:1. Since this solution shows a very low concentration of lead ion it might be expected to give a smooth and adherent cathode deposit. The purpose of this thesis is to determine its possible applicability as a refining electrolyte"--page 1.

A Comparison Of Missouri Sandstones, Llewelyn Lodwick

Bachelors Theses

"Because of the scarcity of fossils in sandstones, the ages of these stones are difficult to determine except by the fossil bearing rocks either above or below them. Consequently, sandstones, even of the same area, are often separated and correlated with difficulty. It is for this reason that an effort is made to determine a means by which each sandstone may be identified"--Introduction, page 1.

An Investigation In Concentrating A Certain Tailing On Wilfley Tables, Theodore Saunders Dunn, Roy Nicoll Mcbride

Bachelors Theses

"The object of this investigation was to determine the adaptibility sic to concentration on a Wilfley table of a certain tailing carrying silver, lead, and zinc. The material was from the tailing dump of the Red Elephant Mine, operated by the Danaher Mining and Milling Company, of Hailey, Idaho, who are now considering treating this material if it can be done economically"--page 2.

Flotation Applied To Basic Ores, Orion Dexter Neal

Bachelors Theses

"Concentration, by flotation, as used in to-day is limited to the ores containing an acid gangue. Although, it is probable, that in a few instances flotation schemes are being used on certain ores containing basic gangue, the processes are carefully guarded as trade secrets. It was with ores containing basic gangue that the experiments embodied in this thesis were made, in an effort to determine some means of concentration and also to determine the best conditions for some of the varying factors"--page 1.

The Determination Of The Critical Sizes In Table Concentration, Julius C. Miller, John N. Webster

Bachelors Theses

"It has been observed in table concentration that the ore band consists of the coarest sic particles of ore on the bottom or low side. Further up on this ore band the coarse particles grade into finer particles, until a certain marked degree of fineness is reached by which the mineral can no longer adhere to the table top, but must be carried over by the wash water as slimes. To determine the critical size of ore of practical value which will remain in the concentrates band, under certain variable conditions, is the purport of this thesis"--Object of Experiment, page …

The Preservation And Interpretation Of Ripple Marks And Sun Cracks, Donald Hewson Radcliffe

Bachelors Theses

"The Roubideaux sandstone (Cambrian) which is rather extensively found in the vicinity of Rolla, Mo., offers exceptional opportunities for the study of ripple marks and sun cracks in place. Fig. 1 shows the principal localities in which these structures are to be found in this vicinity.

The statement is made by Van Hise and others that ripple marks can be used in determining structures, and that to do this it is necessary to be able to tell whether a ripple mark is right side up or overturned. The rule as laid down by them is: That a normal ripple mark …

The Measurement Of Mineral Electrode Potentials, John Charavelle Ingram

Bachelors Theses

"The present investigation was undertaken with a view to consider the variables which tend to cause inaccuracy in the above mentioned measurements and as preliminary to a further study of the subject by the Missouri Bureau of Geology and Mines. The subject is one which, judging from the work of others and from my own experience, will require much more experimentation before results are obtained which are sufficiently reliable for the use of the economic geologist"--Introduction, page 3-4.

Volhard's Volumetric Method For Manganese, John A. Murphy

Bachelors Theses

"The purpose of this article and the data contained is an attempt to show how the percentage of manganese varies with different mounts of zinc salt present. It was also intended to determine the ratio of manganese to oxygen and zinc in the brown percipitate sic obtained upon the titration of manganese sulphate against a permanganate solution in the presence of varying quantities of zinc, but through an oversight the data is insufficient for this purpose"--Introduction, page 2.

A Process For The Separation Of Barite And Sphalerite, Cairy C. Conover, Edwin Robinson Morris

Bachelors Theses

"The present price of zinc has stimulated a greater interest in Sphalerite Barite separations than has been manifested for some time. A great many processes have been worked on and have failed for many reasons, the main one being that the physical characteristics of the ore varied so much. The process that is successful must be independent of these variations. The following process is one that depends on a chemical phenomenon and is adapted to any sphalerite-barite separation. This series of experiments was performed by the authors at the Missouri School of Mines and Metallurgy, Rolla, Mo. and was embodied …

The Determination Of The Settling Velocity Of Certain Minerals Common In Ore-Dressing, Oscar N. Bribach, Robert Winters Johnson

Bachelors Theses

"The object of this thesis is to determine the settling velocity of certain minerals common in ore-dressing work. The minerals used in the experiments were marcasite and chert. These two minerals were chosen because there was a convenient supply of both from which pure and uniform particles could be obtained"--page 4.

Some Assay Problems, James Howard Chase

Bachelors Theses

"The object of this thesis is to attempt to solve a few of the many problems of assaying. Each problem is handled separately from, and independently of the others"--page 1.

Checker Board Drainage Due To Eroded Dikes, Julian Adolph Hielscher

Bachelors Theses

"The conclusions here drawn are the results of observations made during the past ten summers spent in this region while camping, fishing, and hunting; at first, with the native game wardens and fire rangers; later on independently or in company with some of the many tourists who annually visit this delightful region. In this manner it has been possible to cross and re-cross this territory in almost every direction. The highways into this wilderness are the streams and lakes and the only method of travel is by canoe, though short excursions can be made over land by following the paths …

A Study Of The Precipitation Of Iron Di-Sulphide And Its Relation To Certain Types Of Deposits, Vachel Harry Mcnutt

Masters Theses

"Very few of the interesting points bearing upon the formation of iron di-sulphide will be treated in this paper. The laboratory tests made are considered to have been sufficiently thorough to substantiate the ideas set forth so that exhaustive tests were not necessary. While the field evidence was collected largely in the Joplin district of Missouri, the conclusions are sufficiently generalized to be applicable to any district in which pyrite and marcasite have been derived from cold solutions"--page 2.

Ratio Of The Thermal And Electrical Conductivities For Gas Carbon, Oscar Alan Randolph

Bachelors Theses

"The method of F. Kohlrausch for the determination of the ratio of the heat conductivity upside down gamma , to the electrical conductivity k of a substance is of practical value as well as of theoretical interest. Of practical value because there may be obtained from it - with much great ease than by direct methods - the heat conductivity which has immediate applications, not only to the design and construction of furnaces, but to various other matters of such import; of theoretical interest to the physicist, because of the Wiedmann-Franz and its consequent relation to the electron theory; to …

A Comparison Of The Silver Losses Due To Cupellation Using Different Kinds Of Cupels, James A. Taggart, Anton Frederick Karte

Bachelors Theses

"In this thesis our object has been to ascertain the silver losses in cupellation with different kinds of cupel materials, thereby determining the efficiency of the various materials used for making cupels. When beginning this work we hardly expected to find such differences in behavior of the various cupels used. However we refer the reader to our curves to see what really happened"--page 2.

A Sanitary Study Of The Well Waters Of Rolla, Alexander Grosberg, Sam Paul Lindau

Bachelors Theses

"In undertaking the analysis of the well waters of Rolla, it was done with the hope that the factors governing the purity of well waters would be brought out. Such a study would also be of great help in determining the proper location and depth of the wells in the community"--Introduction, Page 1.

A Summary Of The Theories Of The Origin Of The Lake Superior Copper Ores, With Evidences Pertaining Thereto, Eva Endurance Hirdler

Bachelors Theses

"In each of the foregoing theories we obtain sound reasoning in connection with many facts. Therefore a correlation of these facts ought to give us enough material to deduct a sound theory. The most plausible supposition seems to be that all metallic ores are derived ultimately from the interior of the earth, from a great metallographic province, when they are delivered by igneous eruptives near or at the surface"--Conclusion With Reasons, page 29.

Evidence Pertaining To The Origin And Deposition Of Ore Deposits, James Edward Mcgoughran

Bachelors Theses

"In looking over the evidence grouped in the foregoing tables it is at once evident that by far the greater number of the ore deposits are associated with igneous rocks, and that they have resulted from deposition from not solution. It appears that, relatively, deposition by segregation from an igneous magma is of much less importance than deposition from solution, in the formation of ore bodies. However, segregation is the only explanation possible in accounting for some very important deposits, but they are very few in number. In distinguishing between deposits resulting from hot ascending meteoric solutions and those resulting …

Reheating Compressed Air By Internal Combustion, Norman L. Ohnsorg

Professional Degree Theses

"The perfection of a reheater of high efficiency has been discussed and experimented upon for a period of time nearly as long as the application of compressed air itself. At the present time all the reheaters are by the external combustion of fuel as in the case of stoves or furnaces, where the air pipes are carried through the flames or is surrounded by steam pipes, or by some similar contrivance, all of which the heating efficiency of the fuel upon the compressed air is low, due to the great loss by radiation, and hot escaping gases. Reheating compressed air …
