Ammoniacal Sulphate Leach Of Ananconda Zinc Calcine Recovery Of The Zinc By Electrolysis., Authur Jewett Bovee Jr.

Bachelors Theses and Reports, 1928 - 1970

Zinc is produced from ores by two general methods, distillation and electrolysis.

The general principles involved in the electrolytic zinc process of today were known as far back as 1880. Difficulties encountered in purifying the solution for electrolysis and lack of suitable mechanical apparatus were the main reasons that such a long time elapsed before the process was used to produce zinc in commercial quantities.

The Effect Of Impurities On The Electrodeposition Of Zinc From Zinc Sulfate Solution Containing Antimony., Emmitt L. Klebba

Bachelors Theses and Reports, 1928 - 1970

It has been proven by research and years of experience, that before electrolytic zinc is possible, the electrolyte, as zinc sulfate solution must be prepared as pure as is economical. In other words, the ideal electrolyte must only be a solution of one metal - zinc. Every other metal and carbon must be excluded if good recovery and a firm deposit is to be obtained.

Alloys Of Lead And Tellurium, Ettore A. Peretti

Bachelors Theses and Reports, 1928 - 1970

Prior to the last few years little practical use was made of the element tellurium, which is obtained from gold and silver tellurides and from the slimes of electro­lytic copper refineries. Lately, however, more study has been made of its properties when alloyed with other metals. It was the purpose of this thesis to study the effects of the addition of tellurium to lead, particularly in small amounts.

A New Giant Camel, Titanotylopus Nebraskensis, Gen. Et Sp. Nov., Erwin H. Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum

The purpose of this bulletin is to figure and describe a .amel brought to light in the field season of 1933, which seems to be the giant of all camels found in the State. The specimen consists of the right ramus with the symphysial portion. The mandible is 26% inches long, or about the length of one's outstretched arm to the finger tips. This jaw is nine inches longer than that of Camelops kansanus. Such an extraordinary jaw indicates a camel nearly twice as large as Alticamelus altus. In reference to its unusual size we are proposing for it the …

A New Rhinoceros Mount, Trigonias Osborni, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum

On February 9, 1934, a pair of rhinoceroses, Trigonias osborni, was installed in the Founder's Room in Morrill Hall, the Nebraska State Museum. They are figured and accorded brief consideration here in order to maintain the printed records of such acquisitions in the Nebraska State Museum. The two skeletons, carefully posed, were put in the south wall case to be associated with a pair of Diceratherium from Morrill County. and the mounted skeletons of two Brown County Te leo ceras. In this gallery two long built-in wall cases insure ample facilities for the proper installation of six rhinoceroses, for each …

Conodonts From The Quadrant Shales Of Montana, Don R. Cubbage

Bachelors Theses and Reports, 1928 - 1970

Conodonts have not been known to exist in Montana prior to the discovery of the specimens discussed and described in this paper. With this fact in mind, the author has endeavored to correlate the species of seven genera found in the Quadrant formation of Montana with similar micro-organisms from other North American areas.

A New Ovibovine, Symbos Convexifrons, Sp. Nov., Erwin H. Barbour

Bulletin of the University of Nebraska State Museum

In Bulletin 25, entitled The Musk-oxen of Nebraska, the writer figured and briefly catalogued the ovibovines of this State as known at that date. In the meantime an interesting new form unlike that of any species falling within our experience presents itself from the Pleistocene of Cherry County, Nebraska. The new specimen cannot be assigned a place in any of the four following genera: Preptoceras, Euceratherium, Ovibos, or Bootherium, but may possibly be referable to the genus Symbos, to which we are assigning it provisionally. It is so unlike Symbos, however, that it may be a distinct genus. …

Roasting And Leaching Bulk Copper-Zinc Sulfide Concentrates With The Subsequent Recovery Of The Metals By Electrolysis, Carl Wesley Sawyer

Bachelors Theses and Reports, 1928 - 1970

The aim of this research was to investigate the possibilities of roasting and leaching a bulk copper-zinc sulfide concentrate, and the subsequent separation of the metals from the leach solution by electro­lytic deposition.

Bulletin of the University of Nebraska State Museum

The object of the present paper is to provide a suitable brief statement of the present state of knowledge of the Pleistocene geology of Nebraska, for an adequate understanding of the Pleistocene Mammal list, by Mr. C. Bertrand Schultz, which forms Part II of this report. The "outline" is necessarily brief and does not contain many detailed sections, nor lengthy discussions of controversial points. It is lacking in adequate detailed descriptions of new formations and may not be entirely convincing to many readers. The only excuse which the writer can offer for the shortcomings of the following pages is the …

The Hampton Tusk [Manuscript], Emmett J. Cable

Mastodon Tusk Background Material

On September 23, 1933, there was unearthed a large tusk in a gravel pit on the farm of W. S. Heuermann, section 21, Reeve township, Franklin County, about four miles south of the town of Hampton, Iowa. While loading gravel, one of the workmen, Lars C. Jensen, noticed something sticking out of the gravels that resembled a horn. Upon closer examination it was found to be a giant tusk, the largest of its kind, according to the best information available, ever found. The tusk was complete before it was broken by the workmen. The length was 11 feet, 7½ inches, …

The Equilibrium Relations Of Nickel Sulfide With Copper And Sodium Sulfides, Walter A. Hamilton

Bachelors Theses and Reports, 1928 - 1970

The equilibrium relations of many of the metallic sulfides have long been a source of scientific and commer­cial interest, of particular interest, are the sulfides of nickel and copper, since the economic recovery of both of these useful metals, from their ores, involves the formation of a sulfide at some stage of the operations.

A Mounted Skeleton Of Megabelodon Lulli, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

A skeleton of Megabelodon lulli, partly composite, was mounted in the laboratory May 31, 1933, and was formally installed and placed on exhibition in Elephant Hall, June 7, 1933.

Effect Of Manganese And Arsenic Upon Current Efficiency In The Deposition Of Zinc From Zinc Sulphate Solution, Justin Kelly

Bachelors Theses and Reports, 1928 - 1970

Throughout the entire experiment the electrolysis were conducted in an eight-hundred cubic centimeter beaker. An excellent circulation of the solution was assured by means of an electric stirrer, vigorous gas evolution from the anodes, and by means of a regulated feed-discharge system. By means of this balance, solution of the same impurity concentration as that of the electrolyte was fed in the cell just as fast as the discharge was syphoned out.

The Nebraska Meteor And Meteorite Of August 8, 1933, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum

At approximately 10:30 a. m., mountain standard time, on August 8, 1933, a large meteor, traveling in a westerly direction, exploded over the panhandle of Nebraska. The phenomenon was witnessed by many citizens throughout the region, and by a number of students from the University of Nebraska, who were engaged at the time in palaeontological field work in northwestern Nebraska .

The Relation Of The Native Forest Cover To The Physical And Chemical Nature Of The Soils Of The Mammoth Cave National Park Area, Sheppard Walker

Masters Theses & Specialist Projects

This study was undertaken for the purpose of determining the relation existing between the native forest cover and the chemical and physical properties of the soils of the Mammoth Cave National Park area. The study was suggested by certain references in the literature to a correlation existing between forest cover and the geological, chemical and physical nature of soils of this area. The recent attempt at reforestation in the Mammoth Cave National Park area renders such a study timely, and it is believed that the results reported in this paper will materially aid the Mammoth Cave National Park Commission and …

A Brief Study Of The Cherokee Formation Outcrop In Kansas, Roland G. Holmes

Electronic Theses & Dissertations

The Cherokee formation is one of the important rock formations of Kansas. There has been much work done upon the coal beds of this formation but so far as is shown by a search of the available literature, there has been no work carried on making a study of the rock beds of the formation by means of chemical analysis.

This paper is an endeavour to do three things: (1) to make a brief study of the rocks of the Cherokee formation at various horizons, (2) to attempt to show by chemical analysis the position of the land mass from …

Leaching Copper Minerals In The Butte District, Kenneth C. Bellows

Bachelors Theses and Reports, 1928 - 1970

The history of mining in Butte is woven about three of our principal metals. The gold placers first attracted the attention of miners in 1863, and reached their peak production in 1867. Silver was the second metal mined, and this operation required the erection of large mills with a consequent increase in mining activity that made the district a prominent producer. Although the presence of copper in the silver ore had been known, the credit for the first development of the copper veins is due Senator W. A. Clark. The original Colusa, Mining Chief, and Gambetta claims were developed to …

A Study Of Montana Bentonite, William P. Ryan

Bachelors Theses and Reports, 1928 - 1970

Research has been undertaken both under Government and private auspices in an endeavor to develop uses for bentonite. Perhaps, the work done to date has had only in consideration the possible industrial importance of bentonite. No simple, quick methods for the determination of the properties or qualities of any particular bentonite have been developed.

In an attempt to establish whether or not there is a means of making rapid simple determinations of the quality of Montana bentonitic clays, and in particular, with regard to the uses to which the clays may be suited. The problem also involves a study of …

The Calcite Veins Of The Livingston Formation, John Moore Conrow

Bachelors Theses and Reports, 1928 - 1970

An interesting group of calcite veins occur near Livingston Montana in a zone about eight miles wide and forty miles long in the edge of the Plains region of Montana in front of the Main ranges. The zone extends from the Boulder River south of Big Timber, through Springdale and Hunters Hot Springs, to Potter's Basin just north of Wilsall in Park County. The group of veins is particularly interesting because they cut relatively flat lying strata, suggest a structural relation­ship to one another, and they are nearly pure calcite.

The present investigation was to determine the position of the …

A Microscopic Study Of Some Volcanic Rocks In The Vicinity Of Butte, Evan Gustafson

Bachelors Theses and Reports, 1928 - 1970

The rhyolite rocks in the vicinity of Big Butte present a very interesting, though complicated study. It seems that no extensive or conclusive work has ever been done upon these extrusives.

I have found that the rhyolites present a very interesting problem, especially microscopically, and that no doubt an intensive study along these lines will solve the problems concerning age relations of different flows and origin of the magma that produced the material for emanations.

Effect Of Impurities Upon Current Efficiency In The Electrolysis Of Zinc Sulphate Solution, Robert Jess Smith

Bachelors Theses and Reports, 1928 - 1970

There are many elements which are detrimental to the current efficiency in the electrolysis of zinc sulphate solution. Fortunately the majority of these elements are easily removed in the purification process and cause no further trouble. The elements that are likely to cause trouble in ordinary plant operations are antimony, arsenic, cobalt, nickel, manganese and germanium. The following tests were made to determine the mutual effect on the current efficiency when several of the impurities were present in the electrolyte.

A Study Of The Composition Of Zinc Complex Cyanide Solutions By The Conductometric Method, Robert James Woody

Bachelors Theses and Reports, 1928 - 1970

As the method or analysis used up to the present time has failed to give quantitative results in determining the composition of zinc cyanide baths, conductometric methods were adopted in this study. Supplementary tests were also carried out in this investigation.
