A Study And Application Of The Process Of Supergene Enrichment Of Silver Ores., Arthur C. Verling
A Study And Application Of The Process Of Supergene Enrichment Of Silver Ores., Arthur C. Verling
Bachelors Theses and Reports, 1928 - 1970
In many deposits of silver ores the grade of the ore decreases considerably a few hundred feet below the surface. It is believed that in many cases the better ores owe their richness in part to the process of sulphide enrichment. It is recognized, however, that many rich silver ores are hypogene deposits that have been affected very little, if any, by processes of enrichment.

It is estimated that 90 to 95% of the world’s consumption of manganese is used in the steel industry in the form of either ferromanganese or spiegeleisen. The remainder is used in the form of either salts or oxides, chloride, dioxide and monoxide.
A Study Of The Effect Of Oxygen On The Rate Of Dissolution Of Gold In Cyanide Solutions., John A. Cook
A Study Of The Effect Of Oxygen On The Rate Of Dissolution Of Gold In Cyanide Solutions., John A. Cook
Bachelors Theses and Reports, 1928 - 1970
The accepted chemical reactions in the dissolution of gold by cyanide solutions require the presence of gold, cyanide, water, and oxygen. The importance of dissolved oxygen in cyanide solutions as a factor is recognized by those familiar with cyanidation. Manufacturers of cyanidation equipment realize the necessity of oxygen, as shown by the appliances they have developed which are attached to the agitators in order to saturate the cyanide solutions with air.
The Control Of The Grain Size Of Zinc, Oswald J. Wick
The Control Of The Grain Size Of Zinc, Oswald J. Wick
Bachelors Theses and Reports, 1928 - 1970
The use of zinc as a structural metal has been militated against by two of its properties, namely, its low tensile strength and its susceptibility to grain growth. The importance of these factors can be appreciated when it is realized that the tensile strength of coarsely crystalline cast zinc is 4,000 pounds per square inch, while finely crystalline cast zinc has a tensile strength of 12,000 pounds per square inch.
Contact Metamorphism In The Highlands, Frank Trask Jr.
Contact Metamorphism In The Highlands, Frank Trask Jr.
Bachelors Theses and Reports, 1928 - 1970
On the southern margin of the Boulder Batholith, about twenty miles south of Butte in the Highland Mountains, there are many miles of contact between the igneous and sedimentary rocks. As two kinds of igneous rocks and many different kinds of sedimentary rock are present, it is an excellent place for the study of contact metamorphism.

The Effects Of Lime On The Amalgamation Of Gold., Rollien R. Wells
The Effects Of Lime On The Amalgamation Of Gold., Rollien R. Wells
Bachelors Theses and Reports, 1928 - 1970
An amalgam is an alloy of mercury with other metals, and amalgamation is the art of making or forming amalgams. In metallurgical language the word is limited to the means adopted for the recovery of gold and silver from their ores by the use of mercury.
Geology Of Some Gold Deposits Of Montana, Leo Edwin Efraimson
Geology Of Some Gold Deposits Of Montana, Leo Edwin Efraimson
Bachelors Theses and Reports, 1928 - 1970
Gold is one of the rarer metals in nature, and chemically it is one of the most inactive. Gold forms stable, natural compounds with few other elements, and only with metals.
A Treatise On The Use Of Insulating Refractory Brick In Malleable Annealing Ovens, James Joseph Offutt
A Treatise On The Use Of Insulating Refractory Brick In Malleable Annealing Ovens, James Joseph Offutt
Professional Degree Theses
"At frequent intervals, there is developed in the refractory field some product which serves to keep this branch of industry in line in the fast moving modern era. The advent of such materials as high temperature mortars and high alumina, super refractories provided a definite mark of progress. One of the most recent and far reaching developments was made possible by the perfection of light weight, insulating fire brick. This product filled a gap which had long been an aching void to all who had made a careful study of furnaces in an effort to obtain higher efficiency. Formerly, it …
Roofing Granules, Morris Harold Grober
Roofing Granules, Morris Harold Grober
Bachelors Theses
"An abundant amount of chats and clays of various kinds is available in Missouri. In the mining districts of south-eastern and south-western Missouri enormous piles of gang known as chats have accumulated. The mining companies desire to rid themselves of this accumulation and would dispose of the chats at a very low price. In northern Missouri and in the diaspore district of central Missouri suitable clays could be found which may be had for a small royalty, mining and transportation costs. Some of the requirements for roofing granules are that they have (1) a size limited by 10 and 30 …
The Use Of Phosphoric Acid As A Pickling Reagent For Enamels, Alan John Hoener
The Use Of Phosphoric Acid As A Pickling Reagent For Enamels, Alan John Hoener
Bachelors Theses
"A review of the available literature reveals that no one has used phosphoric acid for pickling sheet steel for enameling purposes. Articles have been published indicating the corrosive action of phosphoric acid, but these investigations were carried out in an attempt to find an alloy that would resist the corrosive action of the acid"--Introduction, page 1.
The Effect Of Ammonium Carbonate And Aluminum Chloride On The Porosity Of Refractory Material, William Gail Twyman
The Effect Of Ammonium Carbonate And Aluminum Chloride On The Porosity Of Refractory Material, William Gail Twyman
Bachelors Theses
"At the present time there are many insulating materials on the market. The temperatures at which these may be utilized vary from the lower temperature range of 100 degrees C, to a high temperature range of 2800 degrees C. Those insulating materials falling in the class of low temperature insulators have very little usage in commercial manufacturing processes therefore they will not be discussed in this paper. Materials that have a range from 600 degrees C to 2800 degrees C are of vital importance to the manufacturing processes. It is this type of material which we will endeavor to discuss …

The Use Of Fluorspar As A Flux Ingredient In Ceramic Bodies, Edward Henry Frauenfelder
The Use Of Fluorspar As A Flux Ingredient In Ceramic Bodies, Edward Henry Frauenfelder
Bachelors Theses
"The term "flux" is a relative one and does not refer to any particular class of substances. A flux is any material which will lower the softening, fusion, or liquifying sic temperature of another Bases act as fluxes to siliceous substances while in basic compositions like Portland cement, silica is a flux. Feldspar is a flux for white ware mixtures, and is regarded as a refractory in the low temperature enamels. Although fluorspar is used in considerable quantities in many divisions of the ceramic industry, namely: the glassware division, the enamels division, and in the manufacture of cement, its use …

A Metallographic Study Of Primitive Copper Work., John A. Alley
A Metallographic Study Of Primitive Copper Work., John A. Alley
Bachelors Theses and Reports, 1928 - 1970
The field of archaeology and that of metallurgy appear to be widely separated and in no way related. Work done in recent years, however, tends to show that, in many ways, the metallurgist can supplement and enhance the information gained by the archaeologist, at least in regard to those objects which have been made of metal.
