The Application Of A Laboratory Induction Furnace To The Selective Smelting Of A Montana Chromite Concentrate, James H. Mcmahon May 1942

The Application Of A Laboratory Induction Furnace To The Selective Smelting Of A Montana Chromite Concentrate, James H. Mcmahon

Bachelors Theses and Reports, 1928 - 1970

The purpose of this experimental work was to determine with the utilization of a laboratory sized induction furnace a method whereby a high-iron Montana chromite concentrate could be successfully smelted to yield a product suitable for the subsequent production of standard ferrochrome.


Induction Furnace Smelting Of Montana Chromite, Millard L. Reyner May 1942

Induction Furnace Smelting Of Montana Chromite, Millard L. Reyner

Bachelors Theses and Reports, 1928 - 1970

In 1939 the total world production of crude chromite was approximately 1,167,000 metric tons; of which the United States produced only 3,672 metric tons and imported over 317,500 metric tons. Imports came mostly from the Philippine Islands, Cuba, South Africa, and Rhodesia.


Mineral Occurences In Certain Pegmatite Dikes In Southwestern Montana, Jacob N. Jovick May 1942

Mineral Occurences In Certain Pegmatite Dikes In Southwestern Montana, Jacob N. Jovick

Bachelors Theses and Reports, 1928 - 1970

Pegmatite dikes are rather common in occurrence in parts of southwestern Montana, particularly in a region to the east of the Tobacco Root range 50 to 75 miles southeast of Butte.


Mineralogy And Genesis Of The Vermiculite Deposits At Libby, Montana, Raymond Kujawa May 1942

Mineralogy And Genesis Of The Vermiculite Deposits At Libby, Montana, Raymond Kujawa

Bachelors Theses and Reports, 1928 - 1970

The problem considered in this report is one of the mineralogy and mode of formation of the extremely pure, large bodies of vermiculite. Mineralogically the ultrabasic intrusive, with which the economic mineral is associated, presents an array of rather unusual minerals. The determination of these minerals, their associations, and the sequence of alteration that lead to the formation of the vermiculite bodies, constitutes the problem.


Chromite Deposits Near Red Lodge And Silver Star, Montana, Edmond F. Smigel Apr 1942

Chromite Deposits Near Red Lodge And Silver Star, Montana, Edmond F. Smigel

Bachelors Theses and Reports, 1928 - 1970

The Red Lodge and Silver Star chromite deposits of Montana have stimulated much interest during periods of war. The Red Lodge deposit is 25 miles southwest of Red Lodge which is also the nearest railroad point. Several workings are scattered throughout the area, exposing lense-like ore bodies averaging 33% chrome oxide. Silver Star is a much smaller deposit 5 miles west of Silver Star, Montana, which is its nearest rail­road point. Lenses of chromite are exposed by pits and trench­es, which average approximately 36% chromic oxide.


Recovery Of Manganese From Oxidized Ores As Iron-And Phosphorus-Free Soluble Salts, Emil Pietz Jan 1942

Recovery Of Manganese From Oxidized Ores As Iron-And Phosphorus-Free Soluble Salts, Emil Pietz

Masters Theses

"There is a great demand at present for this country to develop its manganese resources. The hazards encountered because of the present international crisis make it almost impossible to import high-grade ores. Manganese is one of the most important strategic metals because it is vital to the production of steel. After the stock piles are depleted and the imports decreased, the deficit must be supplied by the domestic deposits. A great deal of research has been done to concentrate the domestic low-grade ores but new problems have always been encountered. The differences in the properties of the low-grade ores from …


Some Chromite Deposits In Madison County, Montana, Russell H. W. Chadwick May 1941

Some Chromite Deposits In Madison County, Montana, Russell H. W. Chadwick

Bachelors Theses and Reports, 1928 - 1970

Chromite occurs in Madison County, Montana, in two areas, one three miles southwest of Silver Star, the other five miles southeast of Sheridan. The ore bodies are small, lenticular masses surrounded by metamorphosed sedimentary rocks of the pre-Cambrian Cherry Creek series. The ore was deposited from the hydrothermal solutions which serpentinized the surrounding metamorphic host rocks.


The Electrowinning Of Manganese From Rhodochrosite, Lloyd L. Thompson May 1941

The Electrowinning Of Manganese From Rhodochrosite, Lloyd L. Thompson

Bachelors Theses and Reports, 1928 - 1970

Manganese is commonly known to be a metal of great strategic importance. It is essential in the production of all steels, first as a scavenger to remove oxygen and sulfur, and second as an alloying element in wear-resis­tant steels.


The Inhibitory Effects Of Carbonaceous Materials On The Cyaniding Of Gold Ores., David Currie Jr. May 1937

The Inhibitory Effects Of Carbonaceous Materials On The Cyaniding Of Gold Ores., David Currie Jr.

Bachelors Theses and Reports, 1928 - 1970

Carbon and carbonaceous material have been known to have a deleterious effect upon the cyanidation of gold and silver ores since the very beginning of the process. Organic matter is a common source of impu­rities in cyanide solution, its reducing effect being notorious.


A Metallurgical Study Of Gold Ores, Alfred A. Bloom May 1935

A Metallurgical Study Of Gold Ores, Alfred A. Bloom

Bachelors Theses and Reports, 1928 - 1970

Gold is widely distributed in the earth's crust in small quantities. Gold is found in nature in two forms; the element itself and the compound gold telluride. In all cases, silver in some proportion is an alloying constituent.


The Effect Of Small Amounts Of Chrome Ore On Dry Press Diaspore Refractories, Allen John Reid Jan 1931

The Effect Of Small Amounts Of Chrome Ore On Dry Press Diaspore Refractories, Allen John Reid

Bachelors Theses

"The term "Diaspore" as used in this paper will be used to mean the diaspore clay from which refractory bodies are made. The pure mineral Diaspore (Al₂O₃ . H₂O) has an Al₂O₃ content of 85%, while the best grades of diaspore clay run from 76% to 79% diaspore. Diaspore clay consists of a varying percentage of diaspore, ranging from 60% to 79%, and the remaining percentage as clay. The most objectionable impurities which occure sic in diaspore clay are alkalies. The chief source of diaspore is the central part of Missouri. It occurs in pot hole formations accompanied by "flint" …


Beneficiation Of Manganese Ores, Michael V. Healey Jan 1929

Beneficiation Of Manganese Ores, Michael V. Healey

Masters Theses

"The purpose of this investigation is to study the means of beneficiating domestic manganese ores in order that a marketable product may be made. Within the limits of the paper the term "Manganese ores" is applied to those ores mined primarily for their manganese content, to the exclusion of manganiferous iron and silver ores"--Object, page 1.
