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

"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 …

"The Hanyang Iron and Steel Works is located in the city of Hanyang, Hupei Province, inland on the mighty Yangste Kiang, a distance of one thousand seventy-five kilometers from Shanghai. The Works is at the junction of the Yangste and Han Rivers and covers several acres. The Works was established by the Viceroy Tchan and was to have been located at Shanghai, but His Excellency, the Viceroy, was transferred to Wuchang, so he decided to locate the Works in Hanyang - just on the opposite bank of the Yangste, from Wuchang ... The Works originally consisted of two blast furnaces …
