Page 208 - EMMONS, WH, and LANEY, FB, Preliminary report on the mineral deposits of Ducktown, Tenn.: Bull.
Page 15 - The formations of the semi-crystalline area, as mapped in the Ellijay folio, the only quadrangle in Georgia where they have been studied in detail, are as follows: (1) Great Smoky formation; (2) Nantahala slate; (3) Tusquitee quartzite; (4) Brasstown schist; (5) Valleytown formation ; (6) Murphy marble ; (7) Andrews schist; and (8) Nottely quartzite. Of these the Great Smoky formation covers the greatest area and is the only one in which pyrite deposits are known to occur, so the others need not...
Page 180 - ... the first pyrite-burning acid plant in the South, and to supply this plant the present Tallapoosa and Little Bob mines were opened. The Atlanta plant was operated only a few years, and in 1890 the only pyrite-burning plant in the United States was a small one at Natrona, Pennsylvania. About that time the price of Sicilian sulphur rose from $22.00 to $36.00 per ton, and many acid plants were equipped to burn pyrite, but only lump burners were used, and the Spanish ore was imported at such a low...
Page 185 - ... the contact of this great granite mass. The width of the granite is about 20 miles as it extends southeast almost to Gainesville. At the Chestatee mine the granite contact passes within a few hundred feet southeast of the vein outcrop, but the line of contact can not be exactly determined, since there is a belt of injection gneiss between the hornblende and granite gneisses. The injection gneiss is exposed along the road 200 feet east of the vein. It consists of alternating bands, from a fraction...
Page 182 - ... descriptions of the deposit have been published by Eckel1 and Pratt." Topographic relations. — The relations of the outcrop of the pyrite vein to the property boundaries and topography are shown on the accompanying property map (fig. 13) and topographic map and section (fig. 14), reproduced from NP Pratt's article in the "American Fertilizer." The river level, according to the topographic map of the Dahlonega quadrangle, is between 1200 and 1300 feet. Beginning at river level the outcrop of...
Page 1 - ... there has been practically no production of pyrite in Georgia. In 1916 only two mines reported production. In 1917 five companies—the Standard Pyrite Company, the Georgia Mining Company, the Shirley Mining Company, the Sulphur Mining and Railroad Company, and the Marietta Mining Company—reported a total production of 23,242 long tons, of which about onefourth was lump ore. Besides these the Chestatee Pyrites and Chemical Corporation, the Arizona and Georgia Development Company, and the Southern...
Page 5 - ... the most reliable barometer of general economic and commercial conditions. Under normal prewar conditions over two-thirds of the sulphuric acid produced was used in the manufacture of fertilizers. Under war conditions there is an enormously increased demand since the acid is used in large quantities in the production of practically all high explosives.
Page 4 - The production of pyrite in the United States in 1916, the latest year for which complete statistics are available, was as follows: Pyrites produced in the United States in 19161 State Quantity (long tons) California 145,762 Illinois 20,482 Indiana 772 Ohio 15,551 Virginia 148,502 Other states a 94,487 a Includes Georgia, Missouri, New York, Pennsylvania, South Carolina, South Dakota, Tennessee, and Wisconsin. Production and imports since 1910 have been as follows: Pyrites produced and imported into...
