Initial tests of La Sal shaft ore in the Alkaline Leach Pilot Plant

Initial testing of La Sal ore in the Alkaline Leach Pilot Plant at Grand Junction, Colorado, took place during the period February 15 to March 7, 1955. By the use of an extended leaching time of 112 hours and a temperature of 172°F, a dissolution of 99.1 percent of the uranium was obtained. Three-st...

By the use of an extended leaching time of 112 hours and a temperature of 172°F, a dissolution of 99.1 percent of the uranium was obtained. Three-stage filtration of the pulp gave a soluble loss of 1.5 percent and a filter rate of 276 pounds per square foot per 24 hours, using 0.05 pound of Separan-2610 per ton. The best filter rate obtained was in excess of 600 pounds per square foot per 24 hours. Overall recovery of uranium in the "yellowcake" was 95.7 percent for the entire run. The product assayed 75.5 percent on a dry basis, and slightly better than 80 percent U3O8 if washed on the filter before drying. Indicated reagent consumptions are 20 pounds of caustic soda and 0.1 pound of Separan per ton of ore. Fuel oil requirements for pulp heating were 21.3 gallons per ton of ore. Contract no.
