The Extraction Of Chromate Salts From Montana Chromite, Server Tasdemiroglu

Bachelors Theses and Reports, 1928 - 1970

In this thesis I have tried to determine the suit­able temperature, time and the amount of soda ash and lime needed for the calcining process. The leaching and purification tests were studied experimentally. The earlier process for making chromate from chromite was not the same as is used today. There­fore I have found it useful to put into this thesis the newest method for making chromate salts and their important uses.

The Testing And Concentration Of Lake Chelan Copper Ore, Thor W. Johnson

Bachelors Theses and Reports, 1928 - 1970

The geologic history of the Holden area and Lake Chelan district is an integral part of the history of the Cascade Mountain Range. The structure is very complex and the rocks, which have been subjected to intense metamorphic action, are portions of a roof pendant and consists of gneisses, schists and quartzites that are often difficult to correlate.

Gas Analysis By Absorption, Albert D. Mcmahon

Bachelors Theses and Reports, 1928 - 1970

There is practically only one method of gas analysis. This was worked out many years ago by Bunsen, Hempel, and Winkler and consists in the successive absorption with different chemicals of the various constituents of the gas. The only improvement to this method is the oxidation and combustion of different components of a mixture followed by absorption.

The Investigation Of Different Variables In The Assaying Of Silver Cyanide Solution, Warren M. Mahan

Bachelors Theses and Reports, 1928 - 1970

The assaying of gold and silver cyanide solutions is by no means new. The first method of analysis which is given in the literature is an evaporation method by S. B. Christy in 1896. However, the fire assaying of gold and silver dates further back than this. There is a method of fire assaying for gold and silver given in literature as early as 1556 in Georgius, Agricola’s De Re Metallica book.

The Measurement Of Current Efficiency In Zinc Sulphate Electrolytes Containing Antimony And Cobalt By Hydrogen Evolution, Arthur R. Hard

Bachelors Theses and Reports, 1928 - 1970

The measurement of current efficiency by hydrogen evolution is based on the assumption that the portion of the current which deposits no zinc will release hydrogen. This assumption is correct for solutions containing no impurities electropositive to zinc.

The Geology And Mineralogy Of The Independence Mining District, Alan Kuhlman

Bachelors Theses and Reports, 1928 - 1970

From 1888 until 1893 the district was a booming mining camp. Seven stamp mills were running and ore was be­ing mined from the Independence, King Solomon, Poorman, Golden, Hidden Treasure and Crown claims. The town of Independence, which was on the Boulder River at the fork of Basin Creek, boasted a population of 400 people.

A Study Of Metallic Eutectics, Robert P. Corbett

Bachelors Theses and Reports, 1928 - 1970

All of the metals have definite melting points. When a metal is heated above the melting point, it exists as a liquid. Now if the melt is allowed to cool, it will solidify when a temperature corresponding to the melting point is reached.

However, if one metal is added to another metal, both of which are mutually soluble in the liquid state, a certain effect can be noted. The melt will not solid­ify when the melting point of the pure metal is reached, but will freeze at a lower temperature.

Areal Geology Of The Post-Paleozoic Surface Of The Northwest Plains, William M. Broderick

Bachelors Theses and Reports, 1928 - 1970

Probably most of the area included in this report has been ex­amined to some extent by oil geologists, and most, if not all, of the important domes have been discovered and surveyed thoroughly. In parts of the area, the bedrock is covered by glacial drift or alluvium materi­al, but it is reasonable to believe that no new domal structure will be found. This means that surface examination alone will be insufficient in locating new oil fields, so future prospecting will be dependent, to a great extent, on studies of sub-surface stratigraphy.
