Concentration Of Ores By Flotation, John Gay Reilly, Frank Stillmann Elfred
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 …
Selective Concentration Of A Complex Ore By Flotation, Paul Frederick Pape, Ralph Dale
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 A Joplin Slime By Flotation, Earl Joseph Weimer, Walter Harry Freudenberg
Concentration Of A Joplin Slime By Flotation, Earl Joseph Weimer, Walter Harry Freudenberg
Bachelors Theses
"Concentration of the Joplin slimes by means of flotation is a subject receiving considerable attention at the present time, due to high price of zinc. These slimes are the accumulation of the finer particles of the ore during the milling process, and their zinc content is well worth considering. The practice in the past has been to sluice these slimes into the tailing pond, as no economical method of saving the zinc had been employed. The object of our experiment was to economically extract from these slimes by flotation, a product of sufficient zinc content to be of commercial value"--Introduction, …
Practical Details Of Mine Surveying In Certain Mines Of Northern Mexico, Arturo C. Fernandez
Practical Details Of Mine Surveying In Certain Mines Of Northern Mexico, Arturo C. Fernandez
Bachelors Theses
"The name of this thesis is suggestive of its character. The writer has endeavored to resent in a general way some of the most important details of mine surveying as he has found them in actual practice. For the sake of uniformity the engineering staff in which he worked prepared a set of instructions to be used by the engineers at the various mines. The methods and illustrations described in this paper have been adapted from these instructions and they afford a thorough foundation ready to receive the minor details best adapted to each particular mining district"--Foreword, page ii.
