Vanadium Deposits in the Carrizo Mountains District, Navajo Indian Reservation, Northeastern Arizona and Northwestern New Mexico

Description: From abstract: The Carrizo Mountains vanadium district is in the Navajo Indian Reservation, northeastern Arizona and northwestern New Mexico. From May through October, 1942, two mining companies, operating under lease agreements with the Navajo Service, opened several mines in the district and produced a total of about 6,000 tons of ore, averaging approximately 2.2 percent.

The Preparation of Tungsten Hexafluoride

Description: From introductory paragraph: "Because of the possibility that tungsten hexafluoride might occur as an impurity in uranium hexafluoride it seemed worthwhile to prepare some of the material in order to become familiar with its mode of preparation, reactions, etc."

[Plates I-X]

Description: Illustrations accompanying a report investigating the locations of vanadium-bearing phosphatic shale in West-Central Wyoming and Southeastern Idaho. The set includes seven maps (Plates I and V-X) showing the location of rock formations in the area and three charts (Plates II-IV) showing the correlation between the occurrence of vanadium deposits and the thin persistent beds of phosphate rock, oolite, siltstone, dolomite, and limestone with which they are interbedded.

Table IV - Estimated Reserves of Vanadium-Bearing Rock In Areas of Extraction

Description: Table showing the estimated reserves of vanadium-bearing rock in the Paris-Bloomington, Montpelier, Sublette Ridge, Swift Creek, and Strawberry Creek - Greys River Divide extraction areas in west-central Wyoming and southeastern Idaho. Indicated tonnage and inferred tonnage values are given for each area in millions of tons, along with the percentage of vanadium ore rock, maximum and minimum thickness, and average thickness of the rock in the extraction area.

The Extraction Method of Purification of Uranyl Nitrate

Description: Technical report. Three extractions of a diethyl ether solution of uranyl nitrate with small portions of water are effective in removing rare earths, as is shown by radio-gadolinium and radio-europium tracer experiments. A study of representative ethers, alcohols, ketones, and esters showed that diethyl ether and a mixture of 85% ethyl methyl ketone with 15% xylene are the best solvents for the extraction.

On Certain Phase Equilibria in the Ternary System Uranyl Nitrate--Ether--Water at 25° and at 1°C

Description: This report follows a study that deals with a portion of the ternary diagram previously analyzed, namely the boundary curves which separate the central area of two coexistent liquid phases from the two border stripe representing one-phase liquid systems.

Radiation Problems of the Chemical Plant

Description: "Absorption measurements have been made in a large body of water to evaluate the contribution to the radiation intensity produced by the degradation of radiation without absorption. Radiation intensities three times those expected from a simple exponential absorption were found. Scattering from the air of gamma radiation has been measured and has been found to agree satisfactorily with theoretical predictions. The penetration of radiation through curved pipes in shielding has been measured and … more

The Production of Uranium Metal by Metal Hydrides Incorporated

Description: Synopsis: Metal Hydrides Incorporated was a pioneer in the production of uranium metal on a commercial scale and supplied it to all the laboratories interested in the original research, before other methods for its production were developed. Metal Hydrides Inc. supplied the major part of the metal for the construction of the first experimental pile which, on December 2, 1942, demonstrated the feasibility of the self-sustaining chain reaction and the release of atomic energy.

The Vapor Phase Hydrolysis of the Trichlorides of Lanthanum, Praseodymium, Samarium, and Americium

Description: The following report studies the reactions of vapor phase hydrolysis of the trichlorides of lanthanum, praseodymium, samarium, and americium with gas mixtures of HCl and H2O passing over the solid materials mounted on a cantilever-type quartz fiber microbalance. This report calculates the values of the heats and entropies of the reactions, as well as the heat formation of LaCl3, 1254.9 kcal mol-(-1) that was obtained by determining the heat of the solution of La metal in 1.5M HCl.

Optimum Design of Catalytic Towers

Description: Abstract: "This paper gives an arithmetic method of computing the number of sections required in a catalytic tower to produce a given enrichment. It also tells how to calculate the enrichment of a tower with a given number of sections. The problem of the most economical design of catalytic towers is solved. Methods are given for determining the temperature, the efficiencies of catalyst beds and strippers, the relative production rate, and the water vapor-hydrogen gas ratio which give the optimu… more
