Selective Concentration Of A Complex Ore By Flotation, Paul Frederick Pape, Ralph Dale

Bachelors Theses

"The problem of the Mining Engineer and Metallurgical Engineer who wishes to treat the slimes and fine sands of a complex ore is the recovery and separation of minerals so as to render a subsequent treatment of any mineral profitable. The minerals must be separated into groups which can be treated by different processes, because a combination of numerous minerals is extremely undesirable at the smelting plant. In a lead ore the presence of zinc often depletes its value to such an extent that it is unprofitable to treat it; likewise with other minerals and ores. Many systems of selective …

Concentration Of Ores By Flotation, John Gay Reilly, Frank Stillmann Elfred

Bachelors Theses

"Flotation is a new step in the separation of valuable minerals from gangue. This process has only been in commercial use for about six years. There has been several theories advances as to how the ore is concentrated, and the theory that is now usually accepted is that the oil covers or wets the sulphide mineral particle and does not the gangue; and this mineral particle, by means of induced aid is concentrated on the surface. The authors of this thesis have not attempted to explain the reason or reasons why minerals will float; but have accepted the theories advanced …

Some Studies On The Effect Of Different Storage Temperatures Upon The Fat Constants And Acidity Of Print Creamery Butter, Arthur D. Lynch

Electronic Theses and Dissertations

The observation of butter under different storage temperatures is interesting because of its practical bearing upon the factory phase of the dairy industry. Admittedly butter must be stored. It is consumer steadily. It is produced in varying quantities. It is a perishable product. Economic conditions have created the butte store house whereby uneven supplies may be more evenly distributed. Under all practical storage conditions butter deteriorates. Chemical changes occur, more or less pronounced, injuring the quality and thereby affecting the market value. One of the chief constituents which under goes noticeable chemical change is the fat, which is over 80% …

A Thesis Submitted To The Faculty Of Marquette University, Lester James Myers

Bachelors’ Theses

Since the commerce of a country or city determines its position in the world of finance to such a great extent, it is natural to investigate the conditions which govern the country's or city's demand for its share of this commerce, and see if the natural location, and still does not receive its share of the commerce of the country, there is a decided chance for the investigation and removal of the obstacles which are the cause of this condition.

The Design Of A Twelve Story Reinforced Concrete Warehouse, A. M. Fromherz

Bachelors’ Theses

In submitting this design I do so with the one point in view, namely, to endeavor to determine when reinforced concrete becomes impractical for design purposes.

To produce a maximum condition of loading on the lower floors I have taken up the design of a warehouse which is to carry a live and impact load of 400# per sq. ft., plus the dead load on each of the twelve floors. This condition of loading is not practical for design, but it will produce our desired conditions.

From the design it can be readily seen that the columns become excessive in …

A Thesis Presented To The President And The Faculty Of Marquette University For The Degree Of Bachelor Of Science In Civil Engineering And Bachelor Of Science In Electrical Engineering, Anthony B. Czachurski, Benjamin D. Ratke, Joseph G. Casey, William H. Stephan

Bachelors’ Theses

In the work covered by this thesis it is desired to examine an undeveloped water power for the purpose of producing electrical energy as a commercial comodity. Experience has taught that it is best to ascertain first where the product will find its market, and to follow up a satisfactory showing at that end by determining the power capacity of the source, the feasibility of harnessing the same, and the cost of accomplishing this. This program would be adopted in any commercial enterprise to insure a reliable conclusion, and will be followed as closely as possible in the work covered …

The Decreasing Of City Garbage And Sewage Sludge, O. Henry Babcock

Bachelors’ Theses

At the present time there seems to be no general solution of the problem of garbage and sewage sludge disposal, and the chances are that there never will be. The problem in each city is different so that no set rule can be given that will apply to every city. Therefore it is an original problem with each city, governed by cer­tain conditions existing there.
