The Solubilities Of Alkali Chlorides And Sulfates In Anhydrous Alcohols, Emmet Rudolph Kirn Jan 1930

The Solubilities Of Alkali Chlorides And Sulfates In Anhydrous Alcohols, Emmet Rudolph Kirn

Masters Theses

"A search of the literature for data on the solubilities of inorganic salts in various anhydrous alcohols will show that comparatively little work has been recorded. Most of the work has been done on salts in aqueous normal alcohols and practically all of this data concerns only methyl and ethyl alcohols. This information shows a wide divergence in results with different workers. Perhaps these differences in data may be attributed to an error in that the alcohols may not have been absolutely anhydrous, for even small traces of water greatly affect the solubility of the salts. Again, the methods of …


A Study Of The Electrolytic Determination Of Lead, Philip Hall Delano Jan 1930

A Study Of The Electrolytic Determination Of Lead, Philip Hall Delano

Masters Theses

"The electrolytic determination of lead is one of the most used methods, particularly for control work and where large numbers of analyses have to be run each day. The method is adopted because of its simplicity and because of the small amount of the chemist's time required. It is particularly suited for the determination of small amounts of lead. However, it has been noted that deviations from certain conditions produce results which vary widely from the actual amount of lead present, though results which check with each other may be obtained. Certain elements interfere with the determination and must be …


Laboratory Concentration Of The Missouri Iron Ores Of Iron Mountain And Pilot Knob, Strathmore Ridley Barnott Cooke Jan 1930

Laboratory Concentration Of The Missouri Iron Ores Of Iron Mountain And Pilot Knob, Strathmore Ridley Barnott Cooke

Masters Theses

"The purpose of this investigation was to ascertain whether the more important iron ores of Missouri would be amenable to beneficiation to produce high grade concentrates. In the southeastern section of Missouri are found many small deposits of high grade iron ores, and a few large deposits of comparatively low grade ore. The former consist chiefly of red and brown hematite and limonite ores that are in no need of beneficiation. the low grade iron orebodies are relatively large in extent, and, if they could be beneficiated successully [sic] and economically would be of value. Accordingly, the major portion of …


Salts In Tri-State Mill Waters: Their Ill-Effect On The Flotation Of Zinc And Their Removal, Warren Lincoln Howes Jan 1930

Salts In Tri-State Mill Waters: Their Ill-Effect On The Flotation Of Zinc And Their Removal, Warren Lincoln Howes

Masters Theses

"The application of the flotation process has become one of the greatest innovations in modern ore dressing. In a comparatively short span of years it has grown to be one of the most powerful tools of the ore dressing engineer. Flotation is particularly adapted for the recovery of finely ground mineral and has thus enabled the miner to open up enormous deposits of low grade, disseminated ores for profitable treatment. In conjunction with other methods, the process has raised the recovery in practically every ore dressing plant by the treatment of slimes which otherwise would go to waste, carrying valuable …


A Power Study Of A Laboratory Ball Mill, Frederick Clearman Jan 1930

A Power Study Of A Laboratory Ball Mill, Frederick Clearman

Masters Theses

"Ball milling practice in the ore dressing industry is largely empirical. Although many investigators have worked on various of its phases, the present operating methods are mostly a matter of cut-and-try, with the result that the industry is not guided by its underlying principles. Consequently, practice varies extensively with regard to nearly all conditions of operations. Even in neighboring concentrators such factors as speed, ball charge, and ore load differ in similar ball mills. Since fine grinding is continually becoming of more importance, and often accounts for thirty per cent of the milling cost, it is very necessary that a …


A Study Of The Iodine Content Of Missouri Vegetables And Soils, Charles Jackson Potter Jan 1930

A Study Of The Iodine Content Of Missouri Vegetables And Soils, Charles Jackson Potter

Masters Theses

"Investigations have shown that the iodine content of vegetables, water, and soils has a direct relationship to the goiter incidence of a given region. A few countries, notably New Zealand and Switzerland have made a rather complete survey. In the United States, South Carolina has made the most progress in this direction.

At the present time there are no available records of vegetable and soil analysis for iodine in Missouri. Hunze determined the amount of iodine in waters in Missouri. The connection of his results with the author's results will be seen later.

The present investigation was carried out at …
