The Precipitation Of Calcium Tungstate From Sodium Tungstate Solution, Martin E. Messner

Bachelors Theses and Reports, 1928 - 1970

In view of the great need for tungsten in the present industrial world it is necessary that all known tungsten sourves be utilized to the greatest possible extent. Scheelite ores promise to be an increasingly important source of tungsten, inasmuch as the discovery of vast new deposits has been made and known deposits of high grade ores have practically been depleted.

The Effect Of Manganese On The Age Hardening Of Aluminum-Copper Alloys, Keith P. Burgess

Bachelors Theses and Reports, 1928 - 1970

It is known that age-hardening occurs in alloys of the solid solution type containing a hardening constituent, of a metal or metallic compound which is more soluble in the solvent phase at higher tempertures than at lower temperatures.

A Study Of The Beneficiation Of Low-Grade Domestic Chromite, Darrell Edward Bodie

Bachelors Theses and Reports, 1928 - 1970

Chromite, a strategic mineral, is being consumed in ever increasing quantities in the United States today. Although the United States imports practically all of the chromite that is being consumed, it is gradually becoming necessary to exploit the low-grade deposits that are located within the United States, and also the low-grade deposits of Canada.

A Petrographic Analysis Of The Basal Member Of The Kootenai Formation, Frank E. Coupal

Bachelors Theses and Reports, 1928 - 1970

The basal member of the Kootenai formation in south­western Montana is typically a fine to medium-grained "salt and pepper" sandstone and chert-pebble conglomerate. The section between Delpine, Montana, and Melrose, Montana, generally thickens and markedly coarsens to the West.

The Benefication Of A Low-Grade, Montana Scheelite Ore, Walter G. Parker

Bachelors Theses and Reports, 1928 - 1970

The increasing importance of tungsten as an industrial metal and the recent discoveries of extensive deposits of low-grade tungsten ores in Montana led to the investigation which is reported in this paper. The purpose of this investigation was to determine if a saleable concentrate could be obtained from one of these low-grade, Montana scheelite ores.

Oil Shales In Montana, Richard N. Miller

Bachelors Theses and Reports, 1928 - 1970

Montana has long been known to have very large resources of coal and oil, and undetermined amounts of oil shale. The reserves of coal and oil have been proven, in part, and have been produced commercially, but not much is known about the extent and apparent value of the oil shales. Under present .conditions, and according to standards set by the United States Bureau of Mines, the shales are not of commercial value. They are, however, a potentially valuable mineral resource, and portions of them will possibly be utilized, although not in the near future.
