During the period of April 27 to June 8, 1956, Rio de Oro Dysart Shaft Ore from the Ambrosia Lake District, New Mexico, was treated in the Acid Leach - Resin-In-Pulp Pilot Plant at Grand Junction, Colorado. The report contains information on grinding, leaching, sand-slime separation, ion exchange, solvent extraction of H2SO4 pregnant eluates, and precipitation. Results show the ore to be amenable to the Resin-In-Pulp process.

The preliminary operation of the Acid Leach - CCD - Solvent Extraction Pilot Plant at Grand Junction, Colorado, was conducted from November 8, 1956 to January 3, 1957 using White Canyon ores. The report contains information on the grinding, leaching, and liquid-solid separation by continuous countercurrent decantation. Detailed information is presented on the liquid-liquid solvent extraction of the leach liquor using organic solvents containing di-2-ethylhexyl phosphoric acid or triisooctyl amine. Results show White Canyon ores to be amenable to the Acid Leach - CCD - Solvent Extraction process. Using di-2-ethylhexyl phosphoric acid, reagent consumptions were relatively high, whereas with triisooctyl amine excellent recovery of uranium was obtained with moderate reagent requirements.
