Effect Of The Size Of Particles Of Zinc Ore And Carbon Upon The Rate Of Reduction Of Zinc Ore By Carbon, Keith Oxley Alexander

Masters Theses

"In the retort smelting of zinc ores one of the chief metallurgical problems is to obtain as complete a reduction of the zinc as is consistent with economical operation. Among the factors influencing the completeness of reduction are the temperature and time of distillation, the form in which the zinc exists in the ore, the form of carbon used as reducer, and the size of the particles or ore and reducer"--Introduction, page 1.

A Granular Briquette Resistance Furnace For The Electrothermic Dry Distillation Of Zinc Ores, Milton E. Countryman

Masters Theses

[This thesis] "describes experiments carried on at the Mississippi Valley Experiment Station of the United States Bureau of Mines, Department of the Interior, cooperating with the School of Mines and Metallurgy of the University of Missouri, which had for their purpose the development of a 'granular briquet [sic] resistance furnace' for the electrothermic dry distillation of zinc ores"--page v.

Effect Of Various Factors On The Rate Of Reduction Of Zinc Ferrite, Calamine, And Willemite By Carbon, Foster Cary Nix

Masters Theses

"Zinc ores containing large amounts of ferric oxide, calamine and willemite have been known for a long time among practical zinc metallurgists to be more difficult to reduce than ores of the same type but free from the above named compounds. This has been thought to be due to the high temperatures necessary for the reduction of the zinc ferrite and the zinc silicates by carbon. The ferrite is formed both during the roasting of sulphide ores and during distillation in the retorts, while calamine and willemite are introduced as such in the ores. The amount of ferrite formed during …

Engineering Practice In The Tri-State District, Richard John Stroup

Professional Degree Theses

"Mining operations of the zinc and lead deposits of Southwest Missouri, Southeast Kansas and Northeast Oklahoma forming what is known as the Tri-State District are peculiar in many ways. The 'old country' with its shallow gougings and more or less crude methods has practically passed; methods have been improved with the increased size of operations, and the Engineering Department has grown into an indispensable link in the mining operations of practically all the operating companies. But traditions often die hard. Many phases of mining operations are peculiar to this District alone, and likewise engineering practice has its peculiarities"--page 1.

The Disintegration Of Refractory Brick By Carbon Monoxide, Wilbur J. Darby

Masters Theses

"In experimental work carried on at East St. Louis, Illinois in 1916 and 1917, with a furnace of commercial size for the electrothermic dry distillation of zinc ores, a difficulty that developed was the destruction of the firebrick lining in certain parts of the large condenser. The condenser was satisfactory in other ways, yielding a large proportion of the zinc as liquid metal, with no blue powder; but in order to obtain a proper length of service from the condenser it became necessary to find and overcome the cause of the disintegration of the lining ... it will be evident …

Applications Of Method Of Least Squares To The Adjustment Of Level Circuits: Adjustment Of Elevations In Dawson And St. James Townships, Phelps County, Missouri, Clarence Edward Bardsley

Professional Degree Theses

"An introduction to a thesis on least squares could be drawn out to considerable length in explanation: as the purpose of this thesis has been an investigation in applications of the method of least squares to the adjustment of level circuits, it will be found in the body of the report considerable space has been devoted to the explanation of the different applications of the method, with a view that these investigations may be of use to engineers in the profession; so the introductory remarks will be brief ... The method of least squares takes first rank as an arithmetical …

The Effect Of Sulphur Dioxide Gas On Sweet Potatoes, Cotton, And Sorghum Cane Plants, Milburn Leo Dorris

Bachelors Theses

"The chief allegation made by many of the complainants sic in the vicinity of the zinc smelters is that the emanations from the stacks are detrimental to the yield of the crops, especially Sweet Potatoes and Cotton. They claim that on account of the leaves being burned or bleached, the entire plant is poisoned and weakened and the yield is thereby reduced. It was even claimed by some that the presence of the smoke in the atmosphere around the plant has a weakening effect in that it is cumulative, and, while it does not always visibly show, yet the general …

Investigations In Colloidal Phenol, Charles James Millar

Masters Theses

"In making some experiments with various colloids it was noticed that phenol and water seemingly formed a colloid, so it was deemed advisable to experiment farther and see if this fact could be established. The references on this subject vary widely and for this reason some of them are given here. Ostwald recognised [sic] the colloid state of a phenol-water mixture at the critical temperature but evidently failed to see the possibility of the phenol-water colloid at all temperatures. In the following article I will try to show that the phenol-water mixture forms a colloid, not only at the critical …

The Equilibrium Of The Reaction Zn + Co₂ = Zno + Co, Clarence Ware Burkhart

Masters Theses

"Many attempts have been made in the last twenty years to smelt zinc ores in the electric furnace. The disadvantages of the present retort process have been discussed so often that they need not be dwelt upon here. The principle ones are, the low thermal efficiency of the retort furnace, low metal recoveries, small smelting units necessary, short life of the retorts and the difficulty of treating impure and low grade ores. Electric smelting offers remedies for most of these difficulties"--Introduction, page 1.

The Action Of Tan Bark In The Manufacture Of White Lead By The Old Dutch Process, Elmer List

Masters Theses

"This investigation was undertaken because there is very little definite information in print, regarding the micro-organisms which play such an important part in the Old Dutch Process for manufacturing white lead. The statements concerning this process are very general in character. For instance, one book states, "The first action which goes on is to convert blue lead into basic acetate of lead. This is brought about by the heat of the fermenting tan, causing the evolution of acetic acid from the liquid of the pots." Albert H. Hooker in a little treatise on white lead says: "As it stands now, …

The Middle Ordovician Section In East Central Missouri, Morris James Ingerson, Josiah Bridge

Masters Theses

"One of the most serious difficulties confronting anyone working on stratigraphic problems in the Ozark area is the lack of detailed faunal lists of the various formations. A great deal of general work has been done, but very few detailed faunal studies have ever been published, and correlation of the Missouri section with sections in adjoining states is often difficult.

In a recent paper, Dake has discussed the origin and correlation of the St. Peter sandstone. In this study he found considerable difficulty in correlating the various formations above the St. Peter, and at his suggestion, the present study was …
