An Investigation Of The Possibility Of A Missouri Furnace Obtaining An Iron Ore Supply From The State, Donald Foster Updike

Professional Degree Theses

"The material for this thesis and the observations and conclusions drawn are all the result of the writers connection with a group who were engaged by Brown Brothers to determine the possibility of supplying the St. Louis Coke and Chemical Company with iron ore from the state. The original idea was to try to obtain the Coke Companies complete requirement from the state.

Accident Prevention In Cement Plants, Edward Rees Abbott

Bachelors Theses

"The cement industry as a whole took up accident prevention work along with the pioneers. With the organization of the Portland Cement Association, a Bureau of Accident Prevention was formed. This Accident Prevention Bureau, by sending out literature, holding competitions, collecting and tabulating results of accidents collected from every cement manufacturer and affiliating with National Safety Council as the Cement Section, has made rapid strides each year, until today it is doubtful if any other branch of manufacturers can show more improvement in accident records than the cement industry. In spite of their marked improvements each year, there were 47 …

Hydro-Electric Treatment Of Joplin-Miami Zinc Concentrate, David Francis Walsh

Masters Theses

"The Electrolytic Process is a process capable of almost unlimited mechanicalization. For obvious reasons it is more economic to treat high grade concentrates; yet, the extremely high grade concentrates are not essential. The Electrolytic Process can treat economically concentrates as low as 30.% zinc under certain conditions. It is significant that as the grade of concentrates offered for treatment is lowered, the treatment cost per ton of concentrates decreases for the Electrolytic Process; whereas, it will increase, as previously stated, for the Retort Process. It is seen then that the position of the Electrolytic Process is strengthened where lower grade …

The Roasting And Magnetic Separation Of Wisconsin Ores And The Utilization Of The By-Products, Earl George Deutman

Professional Degree Theses

"In the Wisconsin field, the zinc blende is usually found associated with iron sulphide in the form of marcasite. This ore, after being milled and concentrated at the mines, is sent to separating plants for further treatment by roasting and magnetic separation, inasmuch as the mixed blende and marcasite concentrate, owing to the high iron content, is not suitable for the zinc smelter, and the magnetic separation scheme of separation must be resorted to"--page 1.

A Metallographic Study Of Copper Mattes, Edward James Torrence

Bachelors Theses

"The metallographic knowledge of copper mattes or mattes in general for that matter, although extensive, is, to put it mildly, rather diversified. One authority, for instance, believes that mattes are sulphide dissolving compounds there being no eutectiferous series involved. Another believes that the matte constituents enter into a eutectiferous series, compounds being present. Still a third contends that there are no compounds formed but that a simple eutectiferous range exists between certain limits outside of which the end members of the series form solid solutions with each other. In so far as there exists seeming absolute proof for all of …

High Speed Steel - Its History, Development, Manfacture, Metallography, And Constitution, Including An Extended Bibliography, James Presley Gill

Masters Theses

"There is no doubt but that the making of Steel was known and practiced by the early Greeks probably several centuries before the birth of Christ. There have been discoveries of pre-historic forges and smelters evidently used for the making of iron and steel and it is certain that implements made of these materials dates back to antiquity. As to the methods of making the steels of antiquity there is little known, but it is quite probable since iron has a strong affinity for carbon that in the forging of the iron it's contact with the carbonaceous fuel would absorb …

Some Typical Bridges For Logging Railroad Construction, Frederick Hauenstein

Professional Degree Theses

"In some of the pine regions of the Ozark Mountains, a considerable portion of the country is rolling and rough, comprising a succession of hills and hollows. The most efficient method of logging such a tract is obtained by locating the logging road so as to secure a down grade haul for the logs, with consequent up grade return for the empty cars. This necessitates locating the main line of the railroad along the principal creek, and then laying spurs up the different tributary creeks as they are met. Such a procedure requires much crossing and re-crossing of creeks and …

The Thermal Conductivity Of Refractories, Boyd Dudley Jr.

Professional Degree Theses

"The usefulness of correct data in regard to the thermal conductivity of refractories and other materials used in the construction of metallurgical and industrial furnaces is quite generally recognized. Numerous investigations of this property of refractories have been conducted, and in many cases the published data of different investigators are somewhat conflicting. This is particularly true of figures pertaining to materials intended for use at high temperatures, and it is with such materials that the metallurgist is mot interested. The difficulties in the way of precise determinations of thermal conductivities at elevated temperatures are numerous, and it is not particularly …

Leaching Copper Tailings, Howard Gove Halsey, Frederick Gallaway Moses

Bachelors Theses

"There are, scattered throughout the country, enormous amounts of rock that, by the discovery of a quick, cheap, and practiable sic method of extracting their metallic content could be turned into valuable ores. This has already been accomplished for gold and silver by the adaption of the cyanide method to their treatment. The next in order, both because of the value of the metal and the amount of material available in mill dumps and in the ground, is copper. there are dumps containing millions of tons of this material lying idle because of the fact that with the present methods …

A Series Of Tests On The Condensation Of Zinc Vapor To Metallic Zinc, Frank W. Cody, John W. Greene

Bachelors Theses

"The purpose of this Thesis is to try to show the effect which certain variables, which are always present in practice, have upon the condensation of Zinc Vapors to Metallic Zinc. That these variables can and do play an important part in the Zinc Smelting Industry can be shown from the fact that all of the zinc obtained at the present time is won from ores by reducing the oxide of zinc to metallic zinc by means of carbon. This operation necessarily takes place at a temperature above the boiling point of zinc. This means that the zinc immediately on …
