The Mexican Oil Fields, Raul Chavez
The Mexican Oil Fields, Raul Chavez
Professional Degree Theses
"Owing to the large area involved in this paper it is proposed to give only briefly the history, geology and development of the oil industry in Mexico, as well as to discuss in a general way the present oil legislation which has brought so much comment in the papers and has raised to much diplomatic trouble between the Mexican and United States Governments. This discussion is therefore of a brief nature and only the most culminant features and details of the subject in mind are here treated. The information and data here given were accumulated during personal examination of the …
Investigations To Determine A Possible Source Of The Carboniferous Sandstone Of The Ozark Region, John Hyer Bowles, Lewis Ely Davidson, William Ferdinand Netzeband
Investigations To Determine A Possible Source Of The Carboniferous Sandstone Of The Ozark Region, John Hyer Bowles, Lewis Ely Davidson, William Ferdinand Netzeband
Professional Degree Theses
"In preparing this thesis the object has been to determine, by comparisons, a possible source of the Carboniferous sandstones. It is perfectly obvious that the material came from some older formation. Considering all the possible sources from which the Carboniferous sandstone could have originated, we, have the Pre-Cambrian igneous rocks of the St. Francois Mountains, the basal Cambrian sandstone or the La Motte formation, the Roubidoux formation (chiefly sandstone), and the St. Peter formation (essentially sandstone)"--Introduction, page 4.

This article is by no means intended as a text; the principal object being, as previously stated, to offer a few systems, methods, …
Mining, Concentration And Refining Of American Flake Graphite By The Griesemer Graphite Company, Joseph C. Barton
Mining, Concentration And Refining Of American Flake Graphite By The Griesemer Graphite Company, Joseph C. Barton
Professional Degree Theses
"The Griesemer Graphite Company was incorporated June 3, 1916, under the laws of Alabama, for the purpose of mining, milling and refining of flake graphite...Owing to strong competition in the graphite game, it will be impossible to give many interesting facts and figures in this thesis. The screen analysis worked for after each operation is carefully watched and the preparing of the ore, as well as the sizing of the flake, is one of the most important features in the production of flake graphite, especially that grade required by the crucible makers and the lubricating manufacturers. The carbon content is …

"In order to reduce as much as possible the cost of transportation of the crude oil to the refinery, the city of Minatitlán of Minatitlán County in the State of Veracruz was chosen as the most proper place for establishing the refinery it being in the center of the only oil fields which at that time possessed the "Eagle Mexican Petroleum Co."--page 1.
The Goltra Process Of Concentrating Iron Ores As Developed At Waukon, Iowa, Ernest Wander
The Goltra Process Of Concentrating Iron Ores As Developed At Waukon, Iowa, Ernest Wander
Professional Degree Theses
"The more or less impure iron bearing mineral occurs mixed with a very tenacious clay, in which are also found chert, cretaceous quartz pebbles, pockets of sand, masses of pebbles and sand cemented by hydrous iron oxide, (which in some cases partly replaces the silica) and several varieties of fossils, such as crinoids etc. The impurities mentioned are often an integral part of the ore particles, and are present in varying quantities thruout [sic] the deposit. But, besides the foreign matter which the eye can discern, the apparently pure mineral contains a varying percentage of silica and alumina, (as well …
Comparison Of Operating Expenses And Capital Expenditures Of Two Different Types Of Boiler Rooms Covering Extensions Expected During The Next Twenty Years, George Hewitt Boyer
Comparison Of Operating Expenses And Capital Expenditures Of Two Different Types Of Boiler Rooms Covering Extensions Expected During The Next Twenty Years, George Hewitt Boyer
Professional Degree Theses
"This thesis applies to a central power station located in a rapidly growing manufacturing city with a present population of 40,000. The station is connected by high voltage transmission lines with six hydro and steam generating stations located in other cities. These transmission lines are mainly for emergency purposes so that this report considers that the station here studied will carry its full load. The boiler room is the only part of the station considered in this thesis as a previous study showed that there was ample space in the engine room for turbo-generator for years to come"--Introduction, page 1.
Cyaniding The Buckhorn Clay, Paul Richardson Cook
Cyaniding The Buckhorn Clay, Paul Richardson Cook
Professional Degree Theses
"The Buckhorn, Nevada, gold mine is peculiar in being a shallow kaolinized mass of material with basalt walls, having no direct connection with any of the usual gold bearing rocks, the average ore containing 16% water of hydratum. the cyaniding of this hydrant clayey material offered unusual difficulties compared with the usual gold quartz ore of Nevada. The ore body was thoroughly developed; then the mill was built according to the latest cyanide practice, with such changes as was thought the peculiar nature of this ore demanded. Upon starting the mill, the ore proved more difficulty to handle than had …

An Investigation In Treating A Gold Ore From Custer, South Dakota, Theodore Saunders Dunn
Professional Degree Theses
"The following investigation was undertaken to determine the adaptibility [sic] to amalgamation and cyanidation of a certain ore from the property of Mr. Charles Bush near Custer, South Dakota. A preliminary sample of the ore was obtained and laboratory tests made upon it. A ton lot of the ore was then put through the ore dressing laboratory at the South Dakota School of Mines. Upon examination the large sample was found to differ in value and to some extent in character from the preliminary sample, but the scheme of treatment worked out for the first sample was found to work …

Methods Of Prospecting And Estimating Ore Bodies Of The Wisconsin Zinc And Lead District, Guy Henry Cox
Professional Degree Theses
"The stratigraphy and structure of the Wisconsin Zinc and Lead District are remarkably simple; so simple in fact that one is liable to under estimate their importance in relation to the ore deposits. But four formations are of interest to one operating in this district, all of which are Ordovician in age and which in ascending order are, - the St. Peter sandstone, the Platteville limestone, the Galena dolomite, and the Maquoketa shale"--Geology - Stratigraphy - General, page 1.
Bituminous Coal Mining In Northern Missouri, True Walter Blake
Bituminous Coal Mining In Northern Missouri, True Walter Blake
Professional Degree Theses
"Missouri was the first state west of the Mississippi to produce a commercial output of coal and, although in later years some of the western states have produced a larger yield, still the Missouri mines bid air to hold their present standing as there are hundreds of acres of virgin coal land in this state that will be able to be worked profitably after the eastern coal operators have worked out their thicker veins of coal. The coal is won from the grasp of Mother Earth by either room-and-pillar or longwall systems in the larger mines, each method being employed …
