An Investigation In Treating A Gold Ore From Custer, South Dakota, Theodore Saunders Dunn Jan 1915

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 …

The Electrolysis Of Potassium Lead Tartrate Solutions, Reginald Scott Dean Jan 1915

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.

Flotation Applied To A Mexican Silver Ore, Albert Leo Trent

Bachelors Theses

"The object of this thesis is to determine the advisability of treating this Mexican Silver ore by flotation. To do this it was necessary to determine the degree of crushing, the kind and amount of oil, the amount of acid, the time of agitation, and the dilution of pulp, which would give the best results. From the following tests a suitable conclusion of the best conditions of this ore was determined"--Introduction, page 1.

The Relation Of The Composition Of Petroleum To Its Origin And Occurrence, John Warder Shotwell Jan 1915

The Relation Of The Composition Of Petroleum To Its Origin And Occurrence, John Warder Shotwell

Bachelors Theses

"Petroleum Is a mixture of hydrocarbons. It is a liquid varying from colorless, through yellow and brown to black. It varies from 1.0 to 0.80 in specific gravity, which corresponds to 10° to 45° Beaume. It varies widely in physical properties, such as viscosity, ignition point, polarization of light, etc. Chemically it is composed essentially of carbon and hydrogen, but usually contains impurities such as sulphur and nitrogen. The carbon and hydrogen combine with each other to form certain series, or "chains"--Chemical and Physical Nature, page 1.

Geological Mapping Of An Area Along The Frisco Railroad Between Cuba And Saint James, Willard Miles Benham, William Elliott Jan 1915

Geological Mapping Of An Area Along The Frisco Railroad Between Cuba And Saint James, Willard Miles Benham, William Elliott

Bachelors Theses

"The chief object of the work has been the location of the Roubidoux-Jefferson City contact, if it occurred within a mile of the railroad. Distances and positions along the track were obtained by the use of a map and by counting telephone poles. Other locations were made by obtaining their bearing and distance from these points by the use of a compass and by pacing. Elevations were carried by aneroid barometers, using the railroad elevations at mile points as bench marks. An attempt has been made to locate all important outcrops; but these are shown only on the field map. …

The Design Of A Reinforced Concrete Arch Highway Bridge, Clinton Dewitt Smith Jan 1915

The Design Of A Reinforced Concrete Arch Highway Bridge, Clinton Dewitt Smith

Bachelors Theses

"The Subject of this theses is the Design of a Reinforced Concrete Arch Highway Bridge. In making the Design the crossing of South River Street, Austin Minn., was taken as the hypothetical location of the bridge and the design made with reference to the requirements of this location. These requirements are no more than those for an ordinary rural highway bridge. While in the city of Austin it is not in the route of travel to and from the depots and is hence not subjected to the loads due to heavy freighting. There is however a heavy rural traffic, this …

The Thermal Conductivity Of Refractories, Boyd Dudley Jr. Jan 1915

The Thermal Conductivity Of Refractories, Boyd Dudley Jr.

Professional Degree Theses

"The usefulness of correct data in regard to the thermal conductivity of refractories and other materials used in the construction of metallurgical and industrial furnaces is quite generally recognized. Numerous investigations of this property of refractories have been conducted, and in many cases the published data of different investigators are somewhat conflicting. This is particularly true of figures pertaining to materials intended for use at high temperatures, and it is with such materials that the metallurgist is mot interested. The difficulties in the way of precise determinations of thermal conductivities at elevated temperatures are numerous, and it is not particularly …
