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.

Heat Of Formation Of Slags, George P. Woodhall, Walter Adams Luther

Bachelors Theses

"First it was intended to find out the number of heat units per gram of slag that each individual slag would require. The color and blending of the slag were also to be noted. Causes and any derivations that may appear. If any fixed law was visible it was thought to bring it forth. The percentage of iron oxide and calcium oxide was to be varied and the silicon to bear the same proportion in every case"--Object of Thesis, page 1.

The Mining & Construction Of A Smelter For The Production Of Zinc-White From Western Lead-Zinc Ores, Hector George Sylvester Anderson, V. B. Hinsch

Bachelors Theses

"On account of the high price of the old Dutch process of making white lead and the undesirability of sublimed white-lead as the bulk of the pigment, the use of zinc-white as an adulterant of the lead-white made by the old Dutch process is new extensively used by all paint manufacturers. The advantages of its use in conjunction with white-lead in the manufacture of white paints is the fact that it does not combine with sulphur as does white-lead itself. The specifications of the U. S. Light-house Dept. require 75% of zinc-oxide and 25% of white lead as a mixture. …

The Diente Mining District, Abraham L. Fernandez

Professional Degree Theses

"Like every other camp whose ores are inaccessible to market at a profitable cost, the Diente Mining district has remained hardly developed until the advent of the smelters at Monterey. Since then large sums of money have been invested in the proper installation of machinery for the extraction and transportation of its product, and the deposits have been and are being worked systematically and on a large scale"--page 1.

Notes Relative To The Ores Occurring At Mercur, Utah Together With A General Description Of The Metallurgical Practices Applied To Them At Delamar's Mercur Mines, Daniel Cowan Jackling

Professional Degree Theses

"The most notable increase in the gold production of Utah is due to the extensive operations of DeLaMar's Mercur mines in the Mercur district, which are at the present time producing more than two-thirds of the total tonnage of the entire camp. The nucleus of this great property consist of 143 acres, called the Golden Gate Group, by which name the property is still locally known, was purchased by Captain J. R. DeLaMar in 1895"--page 1.

The Determination Of The Fusing Point Of A Few Igneous And Metamorphic Rocks, Fred H. Perkins

Bachelors Theses

"There are two methods of arriving at the refractoriness of a rock. One is the physical, the other is the chemical. The physical methods attempt to determine it directly by subjecting it to heat, and the temperature obtained is registered by use of numerous methods, a type of each kind I will describe in this paper. The chemical methods attempt to arrive at the result by calculations based upon a chemical analysis, though one or more physical determinations have to be made as a basis for these calculations. As the former method is direct, my operations are based upon this …

Electrolysis Of Water In A Copper Sulphate Solution, Hermann Otto Schulze

No abstract provided.

Design Of A Mining Plant, George C. Clark

Bachelors Theses

"It is to be hoped that in the perusal of this short discussion, the idea will not be lost sight of that the work has been done by a novice - probably a needless caution as the fact is patent at every step. Again, while the work is supposed to be laid along practical lines, no attempt has been made to abbreviate and show merely what is absolutely necessary. As the subject is treated as a thesis and not as a proposition to contractors, the attempt has been made to show the method of arriving at conclusions, and when necessary …

Gold Chlorination, Edwin Thompson Perkins

Bachelors Theses

"In a process of gold chlorination recently introduced and apparently used with success in Southern Australia, potassium permanganate, common salt and sulphuric acid were used as the generators of the chlorine. A series of experiments was made to determine the efficisacy of these reagents and for developing chlorine as compared with other methods in use"--page 1.

Pennsylvania Coal Fields, Arthur D. Terrell

Bachelors Theses

"The use of mineral coal dates back before the Christian Era.

The mining of coal, however, is much more recent.

About the 18th century coal mining began to be scientifically executed.

The area of Anthracite coal fields in Penn. is not quite 500 square miles included in outcrop lines of its lowest beds"--page 1.

Some Quantitative Experiments On The Electro-Deposition Of Copper, Jerrold Roscoe Underwood

Bachelors Theses

"The object of these experiments was to determine in a quantitative way the effect or effects, if any, of these various metals on the purity of the copper precipitated electrolytically. The material worked with was from a copper anode from ( ) carrying a silver, a trace of gold, arsenic and antimony as well as other metalic sic impurities"--Object, page 1.

The Electrolysis Of The Water Of A Copper Sulphate Solution, Ralph Barker

Bachelors Theses

"The idea prevails generally, that when an electric current is passed through a copper sulphate solution, the water will be electrolysed sic when the difference of potential between the electrodes reaches about one and one-half volts. The object of the experiments detailed below was to determine whether or not the density of the solution has any effect on the electrolysis of the water, and if any such existed, to find out if there was any relation between them"--page 1.

Some Experiences With A Pan Amalgamation Mill, Guanacevi, Mexico, Arthur J. Stewart

Bachelors Theses

"The work of the chemist and assayer at a pan amalgamation mill is cheifly sic routine work. The work of one day differs, generally, very little from the work of an other day. But occasionally some contingency arises which taxes his ability to the utmost"--page 2.

Hydraulic Separation, Albert Edwin Eardley, John Simpson Cameron

Bachelors Theses

"Before beginning a discussion of the various experiments performed with the hydraulic separators in the Laboratory of the S. of M., a brief statement as to the principle upon which their working depends, and their functions in the dressing of ores should be given. The crude ore when first delivered from the mine is usually not of sufficient richness to be economically handled by the smelters; it therefore becomes necessary to eliminate as far as possible that part of the ore which is of no material value, and among the various forms of apparatus now in use for this purpose …

Contact Plane Concentration, John A. Rogers, George Walter Dean

Bachelors Theses

"Contact plane concentration depends upon the principle that a thin sheet or film of water flowing over a plane surface may be so adjusted that its quantity and velocity are just sufficient to bear away the lighter particles of gangue, leaving behind only the heavier particles of the mineral to be concentrated, adhering by friction to the plane, the concentrates being removed by any convenient method. Thus we see it is best adapted to the concentration of minerals having widely differing specific gravities but may be used for the concentration of all ores and minerals with any specific gravity whatsoever"--page …

Limitations Of Sizing In Concentration, Walter G. Martin

Bachelors Theses

"All ore reaching the mine mouth consists of two portions, the portion containing the mineral which is valuable, and the gangue or worthless portion. The ultimate object then of concentration is the complete separation of these two portions and in the cases when more than one mineral exists with the gangue, to separate the different mineral products from each other"--page 4.

Crushing Machines, Samuel J. Gormly

Bachelors Theses

"Crushing machines may be divided into: crushers, rolls, and pulverizers. Ore as it comes from the mine is usually in larger lumps which require breaking up preparatory to the subsequent treatment it may receive. For this purpose mechanical means must be employed, and the following pages are intended as a rational treatment of the most approved methods, in ore crushing at the present day"--page 1.

The Cyanide Process For Gold, John C. Reid

Bachelors Theses

"Since the discovery of Cyanogen in the latter part of the 18th century records of many experiments are in existence, showing, that at various periods, exhaustive researches have been made, in which the point at issue was to investigate that property which now constitutes the foundation of what is known to Metallurgical Science of today as The Cyanide Process, vis. The solvent power of alkali cyanides on gold & silver"--page 2.

Russell's Lixiviation Process For Silver Ores, Frank L. Tyrrell

Professional Degree Theses

"It has long been known that there are many ores worked in which a large per cent of silver and gold are continually lost, either in tailings or slimes. As far back as 1848 Dr. Percy suggested the extraction of silver from argentiferous ores, by its conversion into the chloride. The chloride was treated with sodium hyposulphite"--Russell's Process, page 1.
