Bromination Of Gold Ore, Francis Joseph Tayman, Santiago Chamberlain
Bromination Of Gold Ore, Francis Joseph Tayman, Santiago Chamberlain
Bachelors Theses
"The bromination of gold ore, in which the gold is extracted by means of Bromine in water, under local conditions"--page 1.
The Extraction Of Gold And Silver From Ore By The Cyanide Process, Isaac Peter Frazier, Claude Egan Jamison
The Extraction Of Gold And Silver From Ore By The Cyanide Process, Isaac Peter Frazier, Claude Egan Jamison
Bachelors Theses
"The object of our investigation was to determine whether the ore could be treated by the Cyanide Process, and to find the conditions for maximum extraction. The following points were investigated:- 1. Best size for maximum extraction. 2. Best strength of solution. 3. Minimum length of time for maximum extraction. 4. Minimum amount of cyanide solution required"--page ii.

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

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