A Test To Determine The Operating Efficiency Of A Steam Driven Electric Power Plant, Walter H. Rosemeyer, Edward Walter Kane Jun 1913

A Test To Determine The Operating Efficiency Of A Steam Driven Electric Power Plant, Walter H. Rosemeyer, Edward Walter Kane

Bachelors’ Theses

In this test it was desired to determine the amount of water evaporated per pound of coal, and the pounds of steam consumed by main engine per kilowatt-hour output. Because of the existing conditions the test was run on only one boiler but on account of the similiarity of construction the results on the other boilers were assumed to be practically the same. The coal used was Hocking Valley Screenings, abituminous coal, which, from tests conducted by the engineer to determine the fuel best suited to the conditions of the plant, was found to give the most economical results. Since …

Flotation Applied To Joplin Sludge, Thaddeus C. Wilson, Gustaf Axel Hellstrand Jan 1913

Flotation Applied To Joplin Sludge, Thaddeus C. Wilson, Gustaf Axel Hellstrand

Bachelors Theses

"The sludge (fine material) which daily is being sent to the tailing dump by the Joplin mills contains values in lead and zinc often in excess, as to percentage, of that of the crude ore. At present no attempt is being made to treat this It is at this point that it is proposed to introduce some flotation process to supplement the ordinary scheme of wet concentration. With this end in view we have conducted a series of experiments in the flotation of a Joplin sludge"--page 2-3.

The Nature Of The Reactions Occurring In The Distillation Of Zinc From Its Ores And The Effect On The Speed Of These Reactions Due To Certain Variables, Robert Glenn Sickly, Charles Yancey Clayton

Bachelors Theses

"The reactions that occur in the metallurgy of zinc are in general well known as to the end results obtained. The zinc smelter desires a maximum recovery in a minimum time. There are certain factors that govern the fulfillment of this desire. The most important of these are TEMPERATURE, TIME, KIND OF REDUCTION MATERIAL, and THE NATURE OF THE ORE. There is much data available as to the temperatures at which these reactions go on and also there is obtainable some information as to the speed with which these reactions progress, particularly as to the length of time required for …

A Series Of Tests On The Condensation Of Zinc Vapor To Metallic Zinc, Frank W. Cody, John W. Greene Jan 1913

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 …

The Effect Of The Presence Of Certain Base Metals On The Ability Of Amalgams To Catch Gold And Silver, Ray Gould Knickerbocker Jan 1913

The Effect Of The Presence Of Certain Base Metals On The Ability Of Amalgams To Catch Gold And Silver, Ray Gould Knickerbocker

Bachelors Theses

"As a general proposition, the conditions that favor successful amalgamation, and the factors that work against the success of the operation are reasonably well known. We know that if mercury contains certain impurities it will not pick up gold and silver efficiently. We know that if the gold and silver are not in proper condition the mercury will not work as it should. We also know what some of these impurities are, and have some idea as to what condition the gold and silver should be in, but the exact data on these conditions and their effects are lacking. The …

Roasting Pyrite For Magnetism With Minimum Sulphur Volatilization, Dale Irwin Hayes, Clark Watson Wright Jan 1912

Roasting Pyrite For Magnetism With Minimum Sulphur Volatilization, Dale Irwin Hayes, Clark Watson Wright

Bachelors Theses

"In Wisconsin and other zinc mining districts the blende is frequently found associated with pyrite and marcasite. In the Wisconsin district, especially, the marcasite content of the mine-run ore is high being frequently equal to and in many cases greater than the sphalerite content. At time the marcasite and sphalerite together constitute as much as 25 or 30% of the min-run ore. The characteristic milling treatment of this ore is; first, hand-picking, and then over grizzlies, tromells, rougher and cleaner jigs. Owing to the fact that marcasite and sphalerite differ but slightly in specific gravity the jig concentrate obtained is …

Efficiency Of The Missouri School Of Mines Power Plant And Cost Of Operation, Cairy C. Conover, John Richardson Kenney, Louie Lincoln Coover

Bachelors Theses

"These tests were made for the purpose of getting the efficiency of the electric power plant as it was being run and the cost of operating it. Tests were first made on the boilers separately. The load at the time of the test was too heavy for one boiler and too light for tow, part of the steam being used for heating the buildings and for the air-compressor. This made it so that no combined test of the boilers and generating couple could be made until the warm weather came and the laboratories using compressed air were closed, which was …
