The Geology Of The Southern Central Portion Of The Morrison Cave Area., Arthur Talpt
Bachelors Theses and Reports, 1928 - 1970
Morrison Cave is located about 50 miles southeast of Butte, Montana. It was named after the man who discovered it. Later it was taken over by the State and renamed Morrison Cave State Park. Recently the government with the aid of the Civilian Conservation Corps has built a new road to the cave and has made the interior more accessible. The name of the cave is now Lewis and Clark Cavern National Monument.
The Presence Of Rhenium In Montana Manganese Ores., Henry E. Swanson
The Presence Of Rhenium In Montana Manganese Ores., Henry E. Swanson
Bachelors Theses and Reports, 1928 - 1970
Rhenium properties offer many interesting possibilities, therefore any ores containing rhenium would be of considerable value. Its close relationship to manganese in the periodic table led to the belief that manganese ores would be an excellent place to search for the metal. Investigation of the literature of rhenium revealed that no ore was known to contain more than 0.001 per cent of rhenium.

A Study And Application Of The Process Of Supergene Enrichment Of Silver Ores., Arthur C. Verling
A Study And Application Of The Process Of Supergene Enrichment Of Silver Ores., Arthur C. Verling
Bachelors Theses and Reports, 1928 - 1970
In many deposits of silver ores the grade of the ore decreases considerably a few hundred feet below the surface. It is believed that in many cases the better ores owe their richness in part to the process of sulphide enrichment. It is recognized, however, that many rich silver ores are hypogene deposits that have been affected very little, if any, by processes of enrichment.
The Extraction Of Manganese From Manganese Flue Dust., John Raymond Moore
The Extraction Of Manganese From Manganese Flue Dust., John Raymond Moore
Bachelors Theses and Reports, 1928 - 1970
It is estimated that 90 to 95% of the world’s consumption of manganese is used in the steel industry in the form of either ferromanganese or spiegeleisen. The remainder is used in the form of either salts or oxides, chloride, dioxide and monoxide.
The Control Of The Grain Size Of Zinc, Oswald J. Wick
The Control Of The Grain Size Of Zinc, Oswald J. Wick
Bachelors Theses and Reports, 1928 - 1970
The use of zinc as a structural metal has been militated against by two of its properties, namely, its low tensile strength and its susceptibility to grain growth. The importance of these factors can be appreciated when it is realized that the tensile strength of coarsely crystalline cast zinc is 4,000 pounds per square inch, while finely crystalline cast zinc has a tensile strength of 12,000 pounds per square inch.
