The Application Of A Laboratory Induction Furnace To The Selective Smelting Of A Montana Chromite Concentrate, James H. Mcmahon
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
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
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
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
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.
Some Chromite Deposits In Madison County, Montana, Russell H. W. Chadwick
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
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.
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
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.
