This book was released on 1961 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is one of a series prepared by the Federal Bureau of Mines on methods and costs of producing uranium ore on the Colorado Plateau. The information it contains was gathered in 1955-58 and applies to eight small operations. (See fig. 1.) Mining costs have increased since the data were I collected, but the information should be helpful in estimating future costs I at similar deposits. The Bureau of Mines had early experience in the production of carnotite-type ores on the Colorado Plateau. 3 4/ Under a cooperative agreement with the National Radium Institute in 1914-16, the Bureau mined and concentrated carnotite ore for recovery of radium, uranium, and vanadium. The ore was taken from claims in or near Long Park Montrose County, Colo., about 3 mi. south of La Salle Mining Co.'s La Salle mine, which is one of the mines described in this report. The Bureau leased the claims from Crucible Steel Mining & Milling Co., a subsidiary of Crucible Steel Co. of America, and from 1914 to 1916 produced 990 tons of high-grade ore, containing 2.6 pct. U308, and about 2,000 tons of mill-grade ore, containing 0.85 pct. U308. The high-grade ore was shipped directly to a radium-recovery plant built in Denver in 1914 under the cooperative agreement. There, commercial methods of extracting uranium, vanadium, and radium from carnotite ores were developed by Bureau personnel. The lower grade ore was concentrated at a small mill in Long Park before being shipped to Denver. The final recovery was 69,000 lb. of U308 and 8.8 g. of radium. The direct mining cost of producing the high-grade ore, including the labor to hand sort and sack it, was $35.96 per ton. Freighting the ore 58 miles to Placerville, Colo., the nearest rail point on the Rio Grande Southern Railway, cost $25.28 per ton, which included $4.55 per ton for ore bags and twine. Four-or six-horse teams pulled two wagons in tandem and made the round trip in 7 days. Four-horse teams hauled 3 1/2 to 4 tons, or about 105 72-lb. sacks of ore, and six-horse teams hauled 5 to 5 1/2 tons. The cost of shipping the ore to Denver, Colo., including the cost of loading the ore into narrow-gage cars at Placerville and transferring it to standard gage cars at Salida, Colo., was $8.59 a ton. Indirect costs at the mine were $9.92, the amortization charge was $1.19, and royalty was $10.47 per ton. The total cost was $91.41 per ton.

Book excerpt: This information circular is one of a series published by the Federal Bureau of Mines in which the methods and costs of producing uranium ore on the Colorado Plateau are discussed. This report describes the three largest company-operated uranium mines of Climax Uranium Co. - the G-1, the Mineral Joe, and the Frank No. 1. Climax Uranium Co., a subsidiary of American Metal Climax, Inc., was [corporated] May 11, 1950, just 2 years after establishment of the domestic uranium program by the Atomic Energy Commission. Twenty-five years earlier Arthur H. Bunker, now chairman of the board, American Metal Climax, Inc., organized and operated the U.S. Vanadium Co. at Rifle, Colo. 3/ Soon after Climax Uranium Co. was organized, it entered into a contract with the Federal Government to build a uranium-vanadium processing mill in Grand Junction, Colo. Under the contract Climax leased from the Federal Government certain uranium-bearing lands that had been withdrawn from public entry in 1948. From Minerals, Engineering Co. on June 12, 1950, Climax acquired other uranium-vanadium properties on Calamity, Outlaw, and Monogram Mesas in Colorado and on Polar Mesa and in the Yellow Cat area of Utah. To house the milling equipment, Climax leased the old Grand Junction sugarmill building of the Holly Sugar Co. Milling facilities, based on a then new process developed for treating both uranium and vanadium, were completed, and the plant went into production in 1951

Available in PDF, EPUB and Kindle. Book excerpt: This information circular is one of a series of published by the Federal Bureau of Mines describing methods and costs at various mining operations. The Schwartzwalder uranium mine, situated about 20 miles west of Denver Colo., is an important source of uranium ore in the Front Range. Production was begun in 1953, and nearly 36,500 tons of ore had been shipped by September 1, 1958. The mine is operated by Denver-Golden Oil & Uranium Co., Denver, Colo. Much interest has been shown in the property since uranium mineralization was found by Fred Schwartzwalder in 1949. The Atomic Energy Commission, Federal Geological Survey, Office of Minerals Exploration (formerly Defense Minerals Exploration Administration), and Federal Bureau of Mines have done work in the area, and various private concerns have shown interest in the property

Available in PDF, EPUB and Kindle. Book excerpt: Now expanded to include the story of nuclear testing and its consequences, Uranium Frenzy has become the classic account of the uranium rush that gripped the Colorado Plateau region in the 1950s. Instigated by the U.S. government's need for uranium to fuel its growing atomic weapons program, stimulated by Charlie Steen's lucrative Mi Vida strike in 1952, manned by rookie prospectors from all walks of life, and driven to a fever pitch by penny stock promotions, the boom created a colorful era in the Four Corners region and Salt Lake City (where the stock frenzy was centered) but ultimately went bust. The thrill of those exciting times and the good fortune of some of the miners were countered by the darker aspects of uranium and its uses. Miners were not well informed regarding the dangers of radioactive decay products. Neither the government nor anyone else expended much effort educating them or protecting their health and safety. The effects of exposure to radiation in poorly ventilated mines appeared over time.

This book was released on 1959 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: This information circular is one of a series, published by the Federal Bureau of Mines, on methods and costs of mining uranium ore on the Colorado Plateau. This report describes the relatively small-scale operations of the Salt Wash miner: The mining method followed, the equipment used, and the production costs. It describes 10 lease-operated mines of Union Carbide: Nuclear Co. that are typical of Salt Wash operations on the plateau. These mines lie within the Uravan mineral belt3/ and arc in the Gateway, Bull Canyon, and Uravan mining districts. (See fig. 1.) Generally the ore bodies occur as irregular, discontinuous layers of ore minerals within sandstone beds in the Salt Wash member of the Jurassic Morrison formation. The ore bodies sometimes occur as rolls, pod associat with carbonaceous trash, or tabular masses. Their size and erratic distribution preclude the use of a prearranged and uniform stoping system. The mining method is simply to follow the ore and leave open scopes behind.

Book excerpt: This report is one of a series published by the Federal Bureau of Mines to describe methods and costs of mining uranium on the Colorado Plateau. The Navajo Uranium Division of Kerr-McGee Oil Industries, Inc., mines uranium from several deposits of carnotite-type ores, which lie buried in the Lukachukai Mountains on the Navajo Indian Reservation, Apache County, Ariz. the country is rugged and isolated. Constructing and maintaing roads has been a continuous task. The ore bodies occur within the Salt Wash member ofthe Jurassic Morrison formation and are similar to other such deposits on the plateau. The current mining activity in the Lukachukai Mountains is a result of uranium-ore discoveries in 1949, although the Navajos undoubtedly knew of the outcrops of yellow uranium minerals long before that time. The ruggedness of the country and the heavy soil cover over much of the surface hampered prospecting, but probably the main reason the ore was not found sooner is that no one took the trouble to look for it in the Lukachukai Mountains.
