Purification Department Of Zinc Leaching Division At Anaconda, Montana, J. L. Brown Dec 1949

Purification Department Of Zinc Leaching Division At Anaconda, Montana, J. L. Brown

Bachelors Theses and Reports, 1928 - 1970

The original smelter, known as the Upper Works smelter, was located on the north side of the Warm Springs Creek, just 2 miles east of the city of Anaconda and 26 miles from the city of Butte. By the year 1894 this smelter had a capacity of 500 tons of ore a day.


The Vanadium Plant Of The Anaconda Reduction Works, Tom Liss Nov 1949

The Vanadium Plant Of The Anaconda Reduction Works, Tom Liss

Bachelors Theses and Reports, 1928 - 1970

No complete history of mining and smelting will ever be written that does not include a major discussion of the Butte district. The colorful tale of this area plays a major role in the interesting stories of mining. In the fields of mining methods, labor relations end financial manipulations, the Butte area has set a standard.


The Christensen Sillimanite Deposit Southeast Of Dillon, Montana, Everett O. Bracken Jun 1949

The Christensen Sillimanite Deposit Southeast Of Dillon, Montana, Everett O. Bracken

Bachelors Theses and Reports, 1928 - 1970

The minerals sillimanite, kyanite, andalusite, dumortierite, and topaz comprise a group of minerals whose high alumina content and physical properties are particularly desirable in the manufacture of refractory products. Sillimanite is the least plentiful of the minerals of this group, and for this reason it is not used extensively at the present time. However, it would be very desirable to the refractory industry if a suitable domestic source of supply could be established.


A Mineral Dressing And Economic Study Of A Complex Arsenical Ore, Luigi D. Piana May 1949

A Mineral Dressing And Economic Study Of A Complex Arsenical Ore, Luigi D. Piana

Bachelors Theses and Reports, 1928 - 1970

The factors that influence the choice of a method for treat­ment of an ore comprise the technical and economic limitations and advantages, derived in detail and balanced according to the exigencies of the particular situation.


Separation Of Cadmium From Zinc In The Purification Step Of The Leaching Cycle, L. C. Powell May 1949

Separation Of Cadmium From Zinc In The Purification Step Of The Leaching Cycle, L. C. Powell

Bachelors Theses and Reports, 1928 - 1970

The purpose of this investigation is to determine the effect of the factors listed previously by conducting a series of tests that will indicate the ex­tent to which the purification is influenced by time, temperature, zinc oust size, zinc dust quantity, iron concentration, two stage precipitation, and aeration.


Caustic Leaching Of Montana Chromite, Chester Freshour May 1949

Caustic Leaching Of Montana Chromite, Chester Freshour

Bachelors Theses and Reports, 1928 - 1970

Chromite is the most important ore used for the production of chromium and chromium alloys. At present, the domestic production is insignificant as compared with the amount of chromite consumed in the United States.


An Investigation Into The Precipitation Of Copper From Mine Water, Using Sulfur Dioxide To Reduce The Ferric Ion Content, David S. Gleason May 1949

An Investigation Into The Precipitation Of Copper From Mine Water, Using Sulfur Dioxide To Reduce The Ferric Ion Content, David S. Gleason

Bachelors Theses and Reports, 1928 - 1970

The experiments which were preformed showed that sulfur dioxide would reduce the ferric ion content of the mine waters to a very low figure. The reduction in the ferric ion content would improve the efficiency of the precipitation process, and also increase the recovery of copper.


The Psilomelane Mineral Of The Butte District, Montana, Logan E. Davis May 1949

The Psilomelane Mineral Of The Butte District, Montana, Logan E. Davis

Bachelors Theses and Reports, 1928 - 1970

During the last few years a great deal of research has been done in connection with the black manganese oxide minerals. This is especially true of the so called mineral psilomelane. It has been proven without a doubt that the name psilomelane has been used in the past to include a great variety of similar black manganese oxide minerals. By the use of X-ray equipment these minerals have been definitely identified.


An Isopach Map And A Discussion Of The Cambrian Strata In The Central Cordilleran Area, Rudi Forhan May 1949

An Isopach Map And A Discussion Of The Cambrian Strata In The Central Cordilleran Area, Rudi Forhan

Bachelors Theses and Reports, 1928 - 1970

In the past few years intensive studies have been going on concerning Cambrian formations as a locale for orebodies. Many of the dolomites and limestones of southwestern Montana are susceptible to replacement by mineralizing solutions, especially when overlain by a rather impervious layer of shale, as is the Pilgrim limestone of Upper Cambrian time.


The Livingston Formation Of The South Boulder Area, Nelson A. Jones May 1949

The Livingston Formation Of The South Boulder Area, Nelson A. Jones

Bachelors Theses and Reports, 1928 - 1970

The Livingston formation is a thick succession of late Cretaceous lava flows, tuffs, and bedded water-laid volcanic detritus 200 miles long and 100 miles wide lying along the eastern margin of the Rocky Mountains in western Montana from Augusta to Yellowstone Park. It differs markedly within short distances in lithologic character and sequences, and the total thickness may exceed one mile in some places.


Benefication Of An Oxidized Lead Ore From The Franklin Mine Lewis And Clark County, Jack D. Mclenegan May 1949

Benefication Of An Oxidized Lead Ore From The Franklin Mine Lewis And Clark County, Jack D. Mclenegan

Bachelors Theses and Reports, 1928 - 1970

This thesis is concerned with the beneficiation of an oxidized lead ore. Emphasis was placed upon concentration by flotation rather than by gravity methods, although some investigation was made with the Wilfley shaking table. The concentration of lead minerals received most consideration in the problem, but wherever possible attempts were made to increase the silver and gold concentration along with the lead.


An Isopach Map And Discussion Of Triassic Strata In Southern Montana And Wyoming, Robert G. Thompson May 1949

An Isopach Map And Discussion Of Triassic Strata In Southern Montana And Wyoming, Robert G. Thompson

Bachelors Theses and Reports, 1928 - 1970

Oil and gas have been found in the Triassic strata of Wyoming. Although the Triassic has not as yet proven to be a large producing horizon it is very probable that ad­ditional oil will be found in Triassic strata in the future, and it is one of the goals at which oil well drillers aim their tools.


Foraminifera From The Colorado Shale Of North-Central Montana, Higbee G. Williams, David P. Wilson May 1949

Foraminifera From The Colorado Shale Of North-Central Montana, Higbee G. Williams, David P. Wilson

Bachelors Theses and Reports, 1928 - 1970

The use of foraminifera in the determination of geologic age, and in the correlation of strata, is one of the most important techniques in oil field stratigraphic studies. The petroleum industry in many regions relies on these microscopic life forms to determine the positions of oil-bearing horizons and to determine the tops of beds. In northern Montana the Colorado group of strata, a series of about 2,000 feet of dense, dark similar shales, is known to contain foraminifers.


Geological Report Of Conrow Wood Creek Area 8 Miles N.E. Of Whitehall, Montana, Kenneth M. Judd Jan 1949

Geological Report Of Conrow Wood Creek Area 8 Miles N.E. Of Whitehall, Montana, Kenneth M. Judd

Bachelors Theses and Reports, 1928 - 1970

Plane table and pacing methods were used in the mapping of the individual areas, but an automobile traverse was used to tie the independent areas into a composite group that would be useful for the entire zone. All land marks, section corners, roads, fence lines, drainage, and geologic features were plotted in the field and later transferred to a master map.
