Uranium Geology The ore occurs as uraninite adhering to the outside of sand grains in the Wind River formation which rest unconformably upon Cretaceous shales. The ores are relatively low in clay content and generally regarded as exceptionally clean ores from the standpoint of objectionable impurities. The arkosic sands in which the ore occurs are … Read more
In the metallurgical treatment of uranium ores large tonnages must be handled. Many ores are low grade so it becomes necessary to employ systems which can be operated on a continuous basis at low cost. A vast amount of research has gone into the development of suitable processes. One is solvent extraction, which has proven extremely … Read more
The plant was originally designed to treat uranium ores with low lime-high vanadium content from the Lukachukai Mountains. The process utilized is known as the “Acid Cure” and had been developed for the most part by the AEC to increase recovery of vanadium values. Briefly, it involved “pugging” the ore with 10% water and 400-500 … Read more
Uraninite and masuyite are the major uranium minerals, essentially fine grained, in the ores studied. Over 40% of the uranium is distributed in the -8µm fractions compared with copper, which is concentrated mainly in the +8-20µm range. Uranium is concentrated mainly in the copper ore zones, with only marginal levels in the gold-only ores. Poor liberation … Read more
The process flowsheet of Uranium generally outlines the latest proven processes for uranium concentration known as “Resin In Pulp” more commonly referred to as RIP To date it is not applicable to ores containing vanadium, where the vanadium must be recovered. Crushing Uranium Ore Depending upon ore shipment schedules, it is desirable to operate the … Read more
