The Concentration Of A Pyrolusite Ore, Frank O. Blake, Van Hoose Smith Jan 1910

The Concentration Of A Pyrolusite Ore, Frank O. Blake, Van Hoose Smith

Bachelors Theses

"This is the history of an attempt to produce from a pyrolusite ore, a material sufficiently rich in manganese to be of value in the various industries such as the making of speigeleisen and ferro-manganese, the glass manufacturing, and the chemical industries. The greater part of the manganese used in the United States comes from Brazil, India and Russia. Our American ores are, in general, low grade and requires various preliminary concentration to fit them for use. Although we possess in this country a great deal of manganese ore, which could be put into suitable condition for the market, there …

Laboratory Methods For Copper-Nickel Ores, Walter Irving Phillips Jan 1910

Laboratory Methods For Copper-Nickel Ores, Walter Irving Phillips

Professional Degree Theses

"The Sudbury nickel field, situated in the Province of Ontario, Canada, near the northern shore of Lake Huron, was practically discovered when building the Canadian Pacific Railway. The method of deposit is unusual in that it is not a vein filling but a true igneous deposition. The magma carried besides rock making constituents three principle sulphides, viz. - those of iron as pyrrhotite; of copper as chalcopyrite; and of nickel as pentlandite. These three sulphides, being heavier than the rock matter, and, favored by the slow rate of cooling of the magma, had sufficient time to settle into the lowest …

An Investigation Into The Causes Of Accidents To Shot Firers In Bituminous Coal Mines, George Edwin Lyman Jan 1910

An Investigation Into The Causes Of Accidents To Shot Firers In Bituminous Coal Mines, George Edwin Lyman

Professional Degree Theses

"In many cases the explosions which kill so many shot firers can be directly attributed to the presence of gas, or coal dust, but often there will be explosions of terrific violence in mines which are so wet as to preclude the possibility of dust being held in suspension in the air current, and where no gas has been detected in the history of the mine. Such an instance came under the writer's observation some time ago in which his opportunities of investigation were excellent, and the results of which may perhaps throw light on other apparently mysterious explosions of …

Dredging, Swan River, Colorado, Henry William Lohman Jan 1910

Dredging, Swan River, Colorado, Henry William Lohman

Professional Degree Theses

"Operations for the extraction of gold from the gravels of this river, were started about ten years ago, at which time it was attempted by means of hydraulic elevators, later by means of the early type dredge, Risdon design, of which three were installed, and later still, an early type Bucyrus Dredge. These all resulted in failure, some alleged to have been due to impossibility of reaching bed-rock; small yardage capacity; and fraility [sic] of design. these have been overcome in the latest type of dredge constructed by the Bucyrus Company, description of which follow later. Dredging here, differs from …

Metallurgical Operations Of Pyritic Smelting As Carried On At Ducktown, Tennessee, Byron John Snyder Jan 1910

Metallurgical Operations Of Pyritic Smelting As Carried On At Ducktown, Tennessee, Byron John Snyder

Professional Degree Theses

"The Practice of Pyritic Smelting is a comparatively new method. It has made possible the extraction of metals from very low grade ores economically. In fact, the direct smelting of sulphide ores of any sort is a very modern metallurgy. This method is extensively used in the United States and British Columbia and will prove to be very valuable in the future development of other regions. Pyritic smelting may be considered as the oxidizing smelting of pyritic ores in a blast furnace with the view to producing matte which collects the values. A short discussion of copper smelting in general, …

Reheating Compressed Air By Internal Combustion, Norman L. Ohnsorg Jan 1910

Reheating Compressed Air By Internal Combustion, Norman L. Ohnsorg

Professional Degree Theses

"The perfection of a reheater of high efficiency has been discussed and experimented upon for a period of time nearly as long as the application of compressed air itself. At the present time all the reheaters are by the external combustion of fuel as in the case of stoves or furnaces, where the air pipes are carried through the flames or is surrounded by steam pipes, or by some similar contrivance, all of which the heating efficiency of the fuel upon the compressed air is low, due to the great loss by radiation, and hot escaping gases. Reheating compressed air …

A Study Of The Losses Occurring In The Milling And Smelting Of Missouri-Kansas Zinc Ores, Horace T. Mann Jan 1910

A Study Of The Losses Occurring In The Milling And Smelting Of Missouri-Kansas Zinc Ores, Horace T. Mann

Professional Degree Theses

"At the present time the greater portion of the zinc mined in the Joplin District, is taken from what is known as the sheet-ground. What percentage of the zinc bearing rock is extracted or what percentage is left in the ground when the mine is abandoned, which owing to caving and other causes can not be recovered at some future time, is not known. It is to be hoped that the State Geological Survey will in the near future be able to take up the investigation of this subject. Until they do it will be impossible to make a reliable …

A New Copper District In Southern Arizona, Harry Carleton Chamberlain Jan 1910

A New Copper District In Southern Arizona, Harry Carleton Chamberlain

Professional Degree Theses

"Within the last two or three years, the copper mining industry has been growing at a remarkable rate. Perhaps not so much in the output of refined copper as in the exploitation and development of new fields. The panic of 1907 left its mark only too deep on many of the then producing mines. the inflated price of copper has aroused interest in those who owned or controlled small or undeveloped mines ... One of these districts is the one to be treated of in this report. It is not a new discovery, but rather one of the oldest camps …

Radiation Losses In Metallurgical Furnaces, Frank Richard Loveridge Jan 1909

Radiation Losses In Metallurgical Furnaces, Frank Richard Loveridge

Bachelors Theses

"The conduction and radiation of heat are of great importance in metallurgy. Metallurgical operations require, in the great majority of cases, temperatures above those of normal atmospheric conditions. Loss of heat is loss of dollars. Furnaces of all kinds allow to pass their walls a greater or less amount of heat, i.e. heat is lost by conduction and by radiation. This heat is often spoken of as radiation loss. It is due to the heat being conducted from the inside to the outside of the furnace. The materials of construction, and manner of building the furnace has much to do …
