Book Description
This report presents the work performed during the period September 1, 1952 to October 31, 1952 on process development for recovery of uranium and vanadium from carbonate leach solutions. Work presented on the electrolytic precipitation of uranium and vanadium includes studies on cathode materials, diaphragm materials, effects of modifying operating variables and experimental procedure, and tests utilizing the low vanadium leach solution received recently from Monticello. Test work is reported on the regeneration of the barren leach solution in the sodium-amalgam process. Other studies are reported on packed columns, leach solution with high initial pH, mercury losses, and results obtainable with low-vanadium leach solution. Additional studies are reported on the possibilities of adsorption as a recovery method. Qualitative studies on the chemistry of uranium in carbonate solutions are discussed in conjunction with the process development studies.

Book Description
This report presents the work performed during the period July 1, 1952 to August 29, 1952. Test data are given on performance of solution spray columns in the process for the recovery of uranium and vanadium from carbonate leach solutions by sodium-amalgam. Studies are presented on the electrolytic precipitation of uranium and vanadium from carbonate leach solutions using a diaphragm cell with a mercury cathode. Test work includes studies on variation in current efficiency with cathode current density, evaluation of diaphragm materials, separate electrolytic precipitation of uranium and vanadium, use of cathode materials other than mercury, and regeneration of the barren leach solution. The results of a few tests using adsorption as a means for the recovery of uranium and vanadium are given.

Book Description
This report presents the work performed during the period May 1, 1952 to June 30, 1952. Investigation of the sodium-amalgam reduction of carbonate leach solution was continued. Additional tests on the reaction characteristics of the process are presented which extend and confirm the work reported in RMO-2605. Tests were continued to obtain information on the operational characteristics of various types and modifications of column contractors in order to evolve a design best suited for use in a continuous production operation. Work was started on a program for the further investigation of electrolytic reduction of carbonate leach solutions. A diaphragm cell which was designed and constructed for the initial tests is described. The results are presented from a group of exploratory tests made to investigate the possibilities of using char sorption as a step in a process for the separation and/or recovery of uranium and vanadium.
