Concentration Of Manganese Dioxide From Philipsburg, Montana, W. M. Mcauliffe
Concentration Of Manganese Dioxide From Philipsburg, Montana, W. M. Mcauliffe
Bachelors Theses and Reports, 1928 - 1970
Imports of manganese ore probably supply a major proportion of the needs of the United States. Domestic production is reported to be higher than pre-war levels, but does not equal that of the peak production year of 1943. In 1946, the Anaconda Copper Mining Company accounted for 90 percent of the total shipments of manganese nodules, and this company is the largest producer of domestic metallurgical ore in the United States.
Leaching Of Low Grade Rhodochrosite, E. D. King
Leaching Of Low Grade Rhodochrosite, E. D. King
Bachelors Theses and Reports, 1928 - 1970
Although there are many uses for manganese today, none of them approaches its importance as a deoxidizing agent in the manufacture of steels. Without manganese the steelmaking industry would be very seriously handicapped. The metallurgy of manganese has been developed around the high-grade ores, and unfortunately, our reserves of high-grade ores are very limited.
A Preliminary Investigation Of The Hydrometallurgy Of Philipsburg Manganese, W. L. Goodman
A Preliminary Investigation Of The Hydrometallurgy Of Philipsburg Manganese, W. L. Goodman
Bachelors Theses and Reports, 1928 - 1970
In the past the steel industry of the United States has depended almost wholly on imports for its supplies of manganese. Although it is well known that there are enormous deposits of low grade manganese ore in the United States the production of substantial amounts of ferro-grade material from domestic sources presents a field for constructive and practical research.
Geology And Occurence Of Graphite At The Crystal Graphite Mine Near Dillon, Montana, Charles K.W. Hum Hum
Geology And Occurence Of Graphite At The Crystal Graphite Mine Near Dillon, Montana, Charles K.W. Hum Hum
Bachelors Theses and Reports, 1928 - 1970
The problem to be considered embraces the mineralogy and the mode of formation of a very pure and vein-like deposit of crystalline graphite. This deposit is of more than ordinary interest because in its geological relations and in the character of its graphite it shows many similarities to the famous deposits of Ceylon.
Electrolytic Manganese From Aqueous Sodium Manganate Solution, William F. Sullaway
Electrolytic Manganese From Aqueous Sodium Manganate Solution, William F. Sullaway
Bachelors Theses and Reports, 1928 - 1970
The contents of this paper represent attempts to deposit the metal, manganese from sodium manganate solutions. The source of manganese was limited to the nodulized product from roasting rhodochrosite and was therefore chiefly manganese oxide.
Some Leaching Characteristics Of The Butte Rhodochrosite, W. L. Slosson
Some Leaching Characteristics Of The Butte Rhodochrosite, W. L. Slosson
Bachelors Theses and Reports, 1928 - 1970
With the increasing importance of manganese in the metallurgical fields of today and tomorrow, extensive work along the lines of its successful exploitation has been accomplished by many investigators. Since tie current world situation has shut off most of our supply of high-grade manganese ores from foreign sources, the low-grade domestic deposits have entered the fields of investigation very rapidly.
The Determination Of Aluminum In The Presence Of Manganese And Iron By The Use Of A Mercury Cathode, William R. Opie
The Determination Of Aluminum In The Presence Of Manganese And Iron By The Use Of A Mercury Cathode, William R. Opie
Bachelors Theses and Reports, 1928 - 1970
Since 1880, when Wolcott Gibbs made the suggestion that mercury could be used as a cathode in gravimetric electroanalysis, many articles have appeared in literature either criticizing the method or citing successful results which have been obtained by it.
A Study Of The Dissolution Of Pyrolusite In Sulphuric Acid, John J. Worsdell
A Study Of The Dissolution Of Pyrolusite In Sulphuric Acid, John J. Worsdell
Bachelors Theses and Reports, 1928 - 1970
With an eye to the future development of its resources, the large deposits of low-grade manganese ore within Montana's boundaries show great promise of developing an important industry. With the present war demands and the possibility of a future market it is essential that work expended to utilize this important mineral.
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.
An Experimental Investigation Of The Age Hardening Of Copper With Manganese Silicide, Ali Kozak
An Experimental Investigation Of The Age Hardening Of Copper With Manganese Silicide, Ali Kozak
Bachelors Theses and Reports, 1928 - 1970
The subject of the thesis was based upon the theory of precipitation or age hardening of the copper by the compound formed by the Manganese and silicon present in the ternary Cu-Mn-Si alloy. The effect of the heat treatment to such an alloy was to be studied and the best aging time and temperature was to be determined.
Relationships Of Manganese Minerals In The Butte District, Charles F. Parent
Relationships Of Manganese Minerals In The Butte District, Charles F. Parent
Bachelors Theses and Reports, 1928 - 1970
The use of manganese in the steel industry as a deoxidizing and desulfidizing agent makes it a necessity in modern industry, while the various alloy steels using manganese for the quality of toughness are also indispensable. Manganese is also used in the manufacture of such various articles as battery cells, paints and glass.
A Study Of The Concentration Of A Low-Grade Manganese Ore From The Ennis District, John B. Schuettenhelm
A Study Of The Concentration Of A Low-Grade Manganese Ore From The Ennis District, John B. Schuettenhelm
Bachelors Theses and Reports, 1928 - 1970
The purpose of the investigation was to determine the most effective means of concentrating the manganese in the ore. The study was that of identification of the minerals present. This showed the presence of oxides of manganese and iron, and carbonates of calcium and manganese. Methods of investigation were planned to determined whether the ore could be concentrated effectively by gravity concentration methods.
The Electrodeposition Of Manganese From Certain Aqueous Solutions, Fred J. Hill
The Electrodeposition Of Manganese From Certain Aqueous Solutions, Fred J. Hill
Bachelors Theses and Reports, 1928 - 1970
Careful examination of the literature available shows that the electrodeposition of manganese from various aqueous solutions has not been attempted to any great extent. The best method for the electrodeposition of pure manganese consists in the electrolysis of a solution containing manganous and ammonium sulphates.
