Rill Stoping In The Butte District, Butte, Montana, Albert Booth Needham Jan 1925

Rill Stoping In The Butte District, Butte, Montana, Albert Booth Needham

Professional Degree Theses

"Numerous methods of stoping have been used in the mines of the Butte District, Butte, Montana, depending on the shape of the ore bodies, conditions of the walls and presence of fault zones or heavy ground. One of the methods tried out successfully in the past few years is that of using rill stopes, both open and timbered. The ideal conditions for adopting this method of mining require veins with nearly vertical dip so that the ore will slide into the chute. The author attempts to describe the various steps including how the development is done, how the stopes are …

The Fissure System Of El Potosi Mine Of El Potosi Mining Company, Santa Eulalia, Chihuahua, Mexico, Carl E. Millikan Jan 1925

The Fissure System Of El Potosi Mine Of El Potosi Mining Company, Santa Eulalia, Chihuahua, Mexico, Carl E. Millikan

Professional Degree Theses

"The fissures traversing the country were the means of mineralizing the district. The North-South system of fissures have been determined to be pre-mineral, hence the most important. Their intersections with cross fissures are the regions of orebodies, and the intersections have always produced ore of mineable quantity. Especially important are the intersections of fissures in the "favorable" (fossiliferous) limestone beds. The favorable limestones are easily recognizable and can be traced thru all parts of the district because of their distinctiveness and the uniformity of the structure of the region"--Summary, page 19.

Evidence To The Production Of Commercial Oil From The Emerson-Texon Fold, Kurt H. De Cousser Jan 1925

Evidence To The Production Of Commercial Oil From The Emerson-Texon Fold, Kurt H. De Cousser

Professional Degree Theses

"The area consists of a strip of country twelve to twenty five miles wide and nearly seventy miles long, extending from Stiles in Reagan County southwest-ward across Crockett County and Pecos County to the Big Canyon Ranch in Terrell County. Map #2 accompanying this report is a small scale geological map of the general region, which shows the location of the general area covered for this report with reference to drainage railroads &c.. The entire area worked in detail comprises nearly 1300 sq. miles or over 800,000 acres"--Location and topography, page 1.

The Properties Of The Fire Clays Used For The Manufacture Of Zinc Retorts, Adolph Harmon Kuechler Jan 1925

The Properties Of The Fire Clays Used For The Manufacture Of Zinc Retorts, Adolph Harmon Kuechler

Masters Theses

"The ultimate object of this refractories investigation is to develop a body for zinc retorts, or changes in the method of their manufacture, that will result in better retorts than the ones now in use. In doing this, the question of permissible cost must, at all times, be kept in mind. The immediate object of the present phase of this investigation, of which this thesis covers only a part, is to determine the physical and chemical properties of the refractories (fire clays, grogs, bodies, etc.) now used for the manufacture of zinc retorts. This will be a basis for later …


Effect Of The Size Of Particles Of Zinc Ore And Carbon Upon The Rate Of Reduction Of Zinc Ore By Carbon, Keith Oxley Alexander Jan 1925

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.


Effect Of Various Factors On The Rate Of Reduction Of Zinc Ferrite, Calamine, And Willemite By Carbon, Foster Cary Nix Jan 1925

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 …
