Production Of Spelter From Calamine, Merritt W. Yeater

Professional Degree Theses

Calamine is one of the most important ores of Zinc and together with the silicates with which it is almost always associated is extensively employed for the production of Zinc. Smithsonite formerly called calamine when pure, consists of Zinc oxide and carbonic acid containing 52 percent of Zinc. It has a specific gravity of 4.2, hardness 4.5m and color is from pale yellow to green.

The silicate when anhydrous called Willemite, contains 58 percent of Zinc, specific gravity 4, hardness 5.5, and color from white to gray or pale yellow.

When hydrous it is called Calamine, specific gravity 3.16 to …

The Ore Knob Copper Process, Oscar Lachmund

Professional Degree Theses

"The works of the Ore Knob Copper Company are situated in the County of Ashe in the north-western part of the state of North Carolina, about ten miles from the Virginia line at an elevation of 4000 feet above the sea.

The works are 45 miles from the railroad, which makes the transportation very difficult. These unfavorable conditions make it necessary for the owners of the mine to smelt their ores and to send to market nothing except the metal, which alone will bear the cost of transportation. The mine was opened previous to 1860, but has only been worked …

Tunnels And Tunneling, James E. Fulcher

Professional Degree Theses

"A tunnel is defined as a sub-terranean or sub-aqueous way, for purposes of passage. The term is also applied, in mining, to horizontal excavations, such as are commonly called drifts, headings, adits, etc., and used as underground roads, or passages for water or air.

Tunneling, at the present day, has become of such importance, that it is in its-self a profession.

The subject of Tunnels and Tunneling properly treated would require a large volume, but taking into consideration the time and space allotted to the preparation of this thesis, I shall be brief; and in order to treat it to …

Extraction Of Silver By The Wet Way, Justo Garcia Martinez

Bachelors Theses

"The great variety of ores in which silver occurs, usually makes it necessary to employ complicated processes for its extraction.

The extraction of the precious metal admits of two general processes viz. The Dry, and Wet Way and as I have chosen the latter for the subject of my thesis, we will be dispensed with the Dry Way, and will try and give all the processes and forms in which silver is extracted by the Wet Way"--page 1.

Leaching Processes For Silver Extraction, Phil Van Frank

Professional Degree Theses

"The leaching process for the extraction of silver are comparatively modern, being introduced in 1849. They belong to a period in which the metallurgist has brought to his aid knowledge derived from chemical research. Under favorable circumstances leaching procedures process many advantages over amalgamation or smelting. For successful use the ores treated for silver must not contain large per cents of lead, zinc, antimony or arsenic. The objections to these bodies will be named later on. When silver is extracted by smelting or amalgamation, a costly plant is necessary, which requires constant repair and in time wear out and be …

Smelting Processes For Silver Extraction, John R. D. Owen

Professional Degree Theses

"The base metals used for the extraction of silver from its ores by smelting are lead and copper, and the different methods employed may be accordingly classified under the general headings of "extraction by means of lead" and "extraction by means of copper"--page 3.

Limes, Mortars, And Cements, Curtis Alexander

Professional Degree Theses

"Lime, calcic oxide, or quick-lime contains 40 parts of the metal calcium and 16 of oxygen by weight and has a specific gravity, depending on its porosity from 2.3 to 3.8. It is a white alkaline earthy substance, quite infusible and is the only oxide of calcium. It is obtained pure by heating pure calcic carbonate to full redness; which expells the carbonic anhydride"--page 1.

Stresses In Suspension Bridges, William M. Claypool

Professional Degree Theses

"A suspension bridge is one in which the roadway over the stream or span to be crossed is suspended from chains or wire ropes.

A suspension bridge consists of the towers or piers over which the main chains or cables pass; the anchorages to which the ends of the cables are attached; the main chains or cables from which the roadway is suspended; the suspending rods or chains which connect the roadway with the cable and the roadway.

The sub-structure consists of the foundations, piers &c. The super-structure consists of the roadway and the chains or cables"--page 1.

Interoceanic Canal Projects, Frank W. Wilson

Professional Degree Theses

"The construction of a canal to connect the Atlantic and Pacific Oceans has been discussed since the discovery of the New World and the whole world has only been waiting until some feasible and economical plan should be offered by which this construction could be made.

The narrow neck of land lying between the continents of North America and South America seems especially adapted to this purpose and has for years tempted exploring parties thither to seek for a practicable canal route. Of late years however another scheme has been proposed which surpasses in magnitude and in economy as well, …

The Production Of Spelter As Practiced At The Glendale Zinc Works, Arthur Neustaedter

Professional Degree Theses

"Description of the Zinc Works. The "Glendale Zinc Works" are situated in the southern part of the city of St. Louis, on the line of the St. Louis Iron Mountain and Southern R.

Metallurgic Industries Of South Missouri, Philip Gallaher

Professional Degree Theses

"The metallurgic industries of South Missouri consist chiefly of iron, lead and zinc industries. These are widely distributed over the southern counties and in many localities the works are extensive, proving in many cases to be great sources of wealth. In the production of Iron the profit is small. Yet this industry, owing to a growing demand, is steadily increasing"--page 2.

The Systems Of Amalgamation, Floyd Davis

Bachelors Theses

"Mineralogists have shown that gold, with few exceptions, occurs in the metallic state, disseminated in ores or scattered throughout alluvial deposits of old river basins. Silver is quite similar in its occurrence, but it is almost universally found in combination with other elements. The means in which these metals occur forms a large factor in determining the most economical and efficient systems of metallurgical treatment"--page 1.

Hydraulic Mining, Arthur Neustaedter

Professional Degree Theses

Hydraulic-mining has undoubtedly its origin in America and principally in the west, when gold was found in 1848 it was imbedded in strata of clay, land and gravel, the question arose how should we get it out of the clay and etc.? and here is the origin of hydraulic-mining. First there was used the simple “pan”, then something better was found, the “cradle,” and then it came to the “tom”, “sluice” and lastly to “hydraulic mining”, all of these come under the head of hydraulic-mining, but the last which bears that name is resorted to only in situations where the …
