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.

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 …

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.

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.

Bulletin No. 114 - The Movement Of Nitric Nitrogen In Soil And Its Relation To "Nitrogen Fixation", Robert Stewart, J. E. Greaves

UAES Bulletins

In the spring of 1903, we commenced at the Utah Experiment Station a series of experiments, the purpose of which was to study the development and movement of nitrates in irrigated soil. The work was so outlined that it should give some very definite results, both as to the influence of water and the plant, upon the nitric nitrogen content of the soil.

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.

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.

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 …

Bulletin No. 109 - The Nitrogen And Humus Problem In Dry-Land Farming, Robert Stewart

UAES Bulletins

The effect of cultivation and the growth of crops upon the nitrogen and humus content of soils has been studied by various investigators, both in America and Europe. In general, the results of the various investigations indicate that cropping and cultivation are very destructive of the organic. matter and the nitrogen of the surface soil.

A Study Of Some Problems In Cyaniding, Sidney S. Schmidt, Russell B. Caples

Bachelors Theses

"The object of the following tests was rather to determine quantitatively the consumption of Potassium Cyanide and of Sodium Cyanide when agitated by compressed air, and when agitated by compressed air in the presence of iron pyrite and in the presence of iron filings, than to explain chemically the causes for this consumption"--Part One, page 1. "The following tests were made to study the rate of percolation of water, under certain conditions, through pure quartz. the information sought is of importance in the cyanide process. By "rate of percolation" we mean the distance traveled in a unit time, by water …

An Investigation Of Certain Methods For The Determination Of Gold In Cyanide Solutions, James Joseph Bowles
