Progress report for the period May 1, 1952 to June 30, 1952 /

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.From cover: "May 1 - June 30, 1952."Contract AT(49-1)-540."Metallurgy - Raw Materials."This report presents the work performed during the period May 1, 1952 to June 30, 1952.
