Recovery of Uranium From Congo Leach Liquors With Ion Exchange Resins

Description: A method is described for recovery of uranium from sulfuric acid leach liquors of Congo ores using anion exchange resins. Excellent uranium recoveries were obtained in cyclic tests which indicate uranium capacities of 11 to 26 lbs. of U3O8 per cubic foot of resin per day. Preliminary tests indicate that sulfuric acid may be as effective as hydrochloric acid in providing the required acidity in the eluant.

Application of Heavy Media Separation, Flotation and Carbonate Leaching to Congo Ores

Description: The investigation of magnesitic-dolomite uranium ores from Union Miniere du Haute Katanga, Belgian Congo, was undertaken in order to examine the possibility of separating the uranium minerals from the carbonate minerals by Heavy Media Separation or froth flotation; thus reducing the sulfuric acid consumption during the uranium leach. In addition, the effect of carbonate leaching the whole ore and carbonate flotation products was examined.

Remote Control Equipment for Plutonium Metal Production

Description: Design and construction of remote control equipment for plutonium metal production are described. Criteria for the design of the equipment included the following: rubber gloves were to be completely eliminated; all mechanisms were to be built as integral units to facilitate replacement through use of the plastic- bag technique; no accessory equipment such as switches, valves, piping, or cylinders were to be inside the contaminated enclosure unless required to handle the plutonium; and all unitsā€¦ more

Oralloy Cylindrical Shape Factor and Critical Mass Measurement in Graphite, Paraffin, and Water Tampers

Description: Critical mass of an Oy (93.9%) sphere in graphite is given as a function of graphite tamper thickness. It was shown that approximately 20(in) of graphite is effectively infinite and that the approximately 17(in) used herein is approximately 98% infinite. Critical mass measurements of Oy (93.9%) spheres and cylinders of different diameters are given for approximately 17(in) graphite tamper, for effectively infinite paraffin tamper, and for effectively infinite water tamper. From these measuremenā€¦ more

Three-Velocity Neutron Diffusion Calculations for an Untamped Oralloy Sphere

Description: The results of a series of neutron diffusion calculations relating to an untamped Orally sphere are presented in detail in this report. The three-velocity neutron transport theory was taken as the basis for the analytical work preceding the computations. This particular theory, also known as the transport approximation, is defined in LA-1271 and known to be quite accurate for assemblies primarily involving materials of large atomic weight. For a sphere of uniform density and atomic composition ā€¦ more

Technical Progress Letter

Description: It was agreed at the February, 1951 meeting of the Atomic Energy Commission Technical Information Panel that, wherever practical, progress reports should periodically include a list of previous reports issued in the same series. Such a list would greatly facilitate servicing by installation document rooms since requests are frequently received for reports in a specific series. This report lists the Technical Progress Letters from 1944 to date, and is distributed to recipients of the Letters in ā€¦ more

Process considerations additional product concentration facilities in 202-S

Description: This memorandum discusses investigations concerning the coupling step required to adapt a Redox IIBP to a 234-5 feed which have indicated that a single peroxide strike from a solution 50--60 g./1. in product and about 2 M in nitric acid is adequate. Additional work is planned to demonstrate both peroxide and Pu(IV) oxalate strikes under these conditions. The present Redox PR cage product contains 10 g./1. in product and over 500 g./1. in nitric acid, and probably requires tow peroxide strikes; ā€¦ more
