Mine Map And Geology Of Saltpeter Cave, Milan Harrison Detweiler, Frank Edgar Townsend
Mine Map And Geology Of Saltpeter Cave, Milan Harrison Detweiler, Frank Edgar Townsend
Bachelors Theses
"The date of discovery of Saltpeter Cave is not known and there is no way of determining it. Numerous accounts are given of the cave by the oldest settlers in the neighborhood, some of which are both startling and interesting. for instance, it is reported that the soldiers of the Confederate army visited this cave for the purpose of securing guano from which to extract saltpeter for use in the manufacture of gunpowder. This may be the origin of its name"--Geology, Page 1.
The Design Of A Sampling Mill To Treat A South East Missouri Lead Ore, Robert Nathaniel Copeland, Edwin Cook Mcfadden

A Study Of The Efficiency Of Discharge Of Classifier Spigots, Harmon Edwin Minor, James Bunten
A Study Of The Efficiency Of Discharge Of Classifier Spigots, Harmon Edwin Minor, James Bunten
Bachelors Theses
"A knowledge of the amounts of water and sand that will be discharged by classifier spigots under various conditions is of considerable importance in the design of classifiers. Suppose it is desired to discharge fifty tons of sand with an average diameter of 2 m.m. through a spigot orifice, the sand being mixed with 100 tons of water and the entire amount of the mixture being discharged in ten hours from the spigot, which is submerged to a depth of two feet under the water. How large a spigot is required? Problems such as this are by no means uncommon. …
Geology In The Vicinity Of Palmer, Mo., Alfred Nicks Detweiler, John Kavanaugh Forman
Geology In The Vicinity Of Palmer, Mo., Alfred Nicks Detweiler, John Kavanaugh Forman
Bachelors Theses
"This area has been of minor importance in the production of ore on a commercial scale, the ore mined being residual in clay in openings occuring sic in dolomite and with chert, all near the surface, the mining being done by individuals who felt disposed to sink a shaft on some supposedly mineralized spot in the hope of uncovering a few tons or ore. Mining operations have been carried on intermittently for more than a century, so we are told, the early miners breaking the rock by first heating it with a wood fire, and then suddenly cooling it with …
The Concentration Of A Pyrolusite Ore, Frank O. Blake, Van Hoose Smith
The Concentration Of A Pyrolusite Ore, Frank O. Blake, Van Hoose Smith
Bachelors Theses
"This is the history of an attempt to produce from a pyrolusite ore, a material sufficiently rich in manganese to be of value in the various industries such as the making of speigeleisen and ferro-manganese, the glass manufacturing, and the chemical industries. The greater part of the manganese used in the United States comes from Brazil, India and Russia. Our American ores are, in general, low grade and requires various preliminary concentration to fit them for use. Although we possess in this country a great deal of manganese ore, which could be put into suitable condition for the market, there …
Nichrome As A Rheostat Resistance, George C. Vogt
Nichrome As A Rheostat Resistance, George C. Vogt
Bachelors Theses
"Nichrome wire is a high resistance alloy, and is not appreciably effected in its resistance by changes of temperature to which it may be subjected in practice. This was shown by the low temperature coefficient obtained. Nichrome does not deteriorate by heating, as shown by torsion-tests after current has been passed through wire. German-Silver however, becomes brittle. Nichrome in a moist atmosphere corrodes rapidly, but in a relatively dry atmosphere, and heated red hot, no signs of oxidation or corrosion could be seen. By all results obtained as to strength, resistance, etc., Nichrome is superior to German-Silver as a resistance …
Modern Cyanide Practice, Harvey Edson Smith
Modern Cyanide Practice, Harvey Edson Smith
Bachelors Theses
"It is noticable sic that about all of the recent improvements in cyanide practise sic have been along mechanical rather than chemical lines. the use of oxidizers such as air, ozone, sodium peroxide, etc., the use of the salts of lead, and even the addition of a coating of lead to the zinc shavings in the extractor boxes were all recommended when the process was first advocated but sometimes for different reasons. In the early days of the process the addition of hypochlorites, alkaline persulphates, and the use of mercuric cyanide was also investigated but has not proven satisfactory owing …

A Study Of The Electrical Resistance Of Coke, Gas-Carbon, And Kryptol Under Varying Conditions, Benton Franklin Murphy, Reuben Conrad Thompson
A Study Of The Electrical Resistance Of Coke, Gas-Carbon, And Kryptol Under Varying Conditions, Benton Franklin Murphy, Reuben Conrad Thompson
Bachelors Theses
"This thesis was undertaken to make a study of the resistance of coke, gas-carbon, and kryptol when used as resistors in the electric resistance furnace, which daily is becoming of increasing industrial importance. It would appear at first sight that the calculation and design of an electric resistance furnace would be an extremely simple problem, since the whole effect is the change of electrical energy into heat according to Joule's Law; but this is by no means the case, as the resistance of the resistor may change enormously during the run of the furnace. The great difficulty met with is …

A Comparison Of The Solvents Used In The Hydrometallurgy Of Silver, Simon Jochamowitz, Enrique Cavazos
A Comparison Of The Solvents Used In The Hydrometallurgy Of Silver, Simon Jochamowitz, Enrique Cavazos
Bachelors Theses
"Potassium cyanide solutions, hyposulphite of soda solutions, and a mixture called the Russell solution, are the solvents most used to win silver from its ores. We are not the first to attempt comparisons of the solvent powers of the different solutions named. It is difficult, at least we have found it difficult, to find tabulated, a comparison of the various solvents from the points of view of speed of action, of consumption of reagents, of suitability of one or another to a given type of ore"--page 1.
Minerals And Their Environment Of Formation, Deforrest Don
Minerals And Their Environment Of Formation, Deforrest Don
Bachelors Theses
"The history of mineralogy began with the development of mining and the use of certain minerals as useful products, such as lime, pigments and precious stones. In order to know how to distinguish these minerals when found and where they were likely to found, it was necessary to study the nature, properties and the modes of occurrence. In order to determine all these properties, it was necessary to classify and compare them with the purpose of ascertaining how they resemble each other, and how they differ"--page 1.

The Volatilization And Absorption Of Silver Chloride, Edgar Joseph Wolf, Victoriano Elicano
Bachelors Theses
"The purpose of this thesis was to study the relation of the loss of silver chloride to such variables as the temperature, as the type of gangue, as the method of carrying on the roast; to determine what becomes of the silver lost and to attempt to recover it. In our work we consider something seemingly overlooked by many, if not all of the workers; namely, that there is a great loss of silver chloride due to absorption, as well as to volatilization. Volatilization has been the hobby of most of the experimeters. We hope to show as a part …
A Study Of The Losses Of Gold During Cupellation In The Presence Of Tellurium, George Albert Easley, Carl Winthrop Keniston
A Study Of The Losses Of Gold During Cupellation In The Presence Of Tellurium, George Albert Easley, Carl Winthrop Keniston
Bachelors Theses
"It is generally accepted that the presence, in the lead button, of a small amount of tellurium causes, during cupellation, a loss of gold. Little, however, is known as to the loss, when tellurium is present, due to variation in the temperature of cupellation...Our work was carried on with the intention of determining the loss of gold, due to temperature in the presence of known amount of tellurium and to compare this loss with that caused by the temperature alone. Has temperature the same, a greater, or a less effect on the loss of gold during cupellation when tellurium is …
