Notes On Phelps County Ores, John Morgan Price, Evan Edmund Price

Bachelors Theses

"In conclusion, summing up the evidence both field and theoretic, there are very good reasons for believing that the deposits which have been worked and are not being worked are not the only deposits of magnitude in the county but by intelligent prospecting along lines already suggested other large and valuable deposits will be found. From the manner of the ores concentration it is not to be expected that every deposit will have a surface outcrop neither is it probable that every depression will be found to contain an ore deposit but when these phenomena occur, together with other evidences …

Studies In Ore Deposition, Cyrus Edward Minor

Bachelors Theses

"The artificial preparation of natural occuring sic minerals is a matter of great interest and importance in the study of the conditions and processes involved in the deposition of ores. In a large number of instances, no difficulty is experienced in the laboratory manufacture, e.g. of calcite, arragonite, dolomite, strontianite, gypsum and other similar minerals may be obtained by crystallization out of molten masses, e.g. graphite, diamond, corrundum sic , etc.: still other cases in which special processes have been employed, have led to the production of compounds in the form in which they occur naturally. the facts so accumulated …

The Electrolytic Refining Of Copper, Lewis S. Logan, Frank R. Bell

Bachelors Theses

"Although copper can be separated from its solution by means of the electric current and the amount so separated varies directly as the current, there is a point in each and every solution where on account of the energy given off to the ions, the copper will be carried over in a more or less impure state, depending upon the strength of the current, the strength of the solution,whether it is saturated or only partly saturated, or whether normal basic or acid and also upon the amount of impurities in the solution. It is the purpose of this thesis (1) …

Methods Of Discharge Measurements Of Streams, Royal Sylvester Webster, Walter Adams Luther

Bachelors Theses

"The method of determining the discharge of large streams is that in which the area of cross section is multiplied by the velocity per. sec. of the water passing through the section. The velocity can be measured by the following methods: 1. By floats. 2. Current Meters. 3. Pitots tube. 4. Can be determined by use of Kutter's formula"--page 1.

Professional Degree Theses

"In the fall of 1901, the writer was engaged by the Republic Coal Mining Company of Aurora Springs, Miller County, Missouri, as Engineer in charge of operations connected with the opening up of their coal mine. The data in this report was never submitted to the owners of the property, because of a request from them that the work of opening up be pushed as rapidly as possible, and [the] mine be put in condition to ship coal; and because the data embraced facts already known to the management, who were determined to open the property regardless of the evidence …

Drainage Of Mines, William Melvin Weigel

Professional Degree Theses

"Before going into the means employed for unwatering a mine, let us consider:--

I. The causes of Occurrence of water in Mines. The drainage of a mine is one of the operations, which, without contributing directly to the output is indispensible in carrying on the work.

By drainage we designate not only the means employed for preventing the influx of water into the workings, but also the means employed of getting rid of what inevitably finds its way into the workings in greater or less quantity.

The water in the mine obtains entrance in various ways.

Sometimes it merely filters …

Cyanide Practice, John A. Rogers

Professional Degree Theses

"The ENCINO CYANIDE PLANT was erected for the treatment of old accumulated tailings, which were worked by the "Patio" and "Cazo" processes. As with most accumulated tailings, which have been exposed to the action of the air for a considerable period, they have undergone changes, whereby, forming compounds which are highly detrimental to a solution of Potassium Cyanide and the direct cause of the present high consumption of Cyanide"--page 1.

The Destructive Distillation Of Pine Sawdust, Frederick Hauenstein, Herbert Arno Roesler

Bachelors Theses

"In many of the pine regions of the South, the operation of saw mills gives rise to immense quantities of waste products, such as slabs and sawdust. The sawdust especially, is of no practical value, accumulating in vast amounts; and, being very difficult to burn or otherwise dispose of, becomes a nuisance around the camp. The object of this thesis is to devise some means of utilizing the sawdust by recovering such constituents as might be of commercial importance "--page 1.

Report On The Reed, Stimson And Kelley Copper And Iron Banks Of Phelps County, Mo., Albert Hill Fay, Carlos E. Martinez

Bachelors Theses

"PRELIMINARY STATEMENT with reference to the formation of limonite and hematite, the principal iron ores of the Ozark District. Iron and copper in solution as sulphides, coming in contact with lime or magnesium carbonates, will be precipitated as pyrite or marcasite and chalcopyrite. Hence the origin of this class or ores. These will in time oxidize to magnetite or hematite, and these in turn will form limonite, and the copper sulphide, or chalcopyrite, is oxidized to the carbonates, malachite and azurite"--page 1.

Aluminum As A Commercial Conductor Of Electric Energy, George Edwin Lyman, Edward J. Morris

Bachelors Theses

"In considering the adaptability of any metal to serve as a distributing agent of electrical energy, the investigation must shape itself along three lines, viz, - the electrical, the physical and the chemical properties which the metal may possess. Evidently a deficiency in any of these properties, if serious, will debar it from successfully coping in the market with its competitors. A metal may have excellent conductivity and its behavior electrically may be thoroughly satisfactory, but if it lacks strength, physically, or ability to resist the destructive forces of the atmosphere, chemically, it is obviously inadaquate sic to serve as …

The Sinking Of Piers On Red River Bridge On Kansas City Southern Ry., Albert Spengler

Bachelors Theses

"In September, 1899, began the work on the construction of the substructure for the Red River Bridge for the Kansas City Southern Railway at Index, Texas, ten miles north of Texarkana, Texas. The new substructure was located about one hundred feet up stream from the old one, consequently it was not necessary to maintain traffic during construction. The object of the new bridge was to replace a much lighter one, which was too light for the increased weight of rolling stock of the railroad company. The substructure consists of seven piers, including a pivot pier, and two abutments. The seven …

Prospecting In Western Mexico, Theodore S. Delay

Professional Degree Theses

"This article is dedicated and addressed to any man who contemplates a prospecting expedition in Mexico. I have made no attempt at a display of literary elegance, or scientific erudition. My aim has been to point out and explain such of the conditions of the business as are peculiar to Mexico. If any one, after having perused these pages, should find himself thereby the better able to cope with the difficulties of such an expedition, a rather unprofitable experience of the writer will have been not wholly fruitless"--page 31.
