Abstract
Correlations were made on experimental data for four New Mexico ore series to determine relationships between ore grade and uranium extraction during leaching operations. Such relationships provide information needed to predict the long-range supply of minerals to meet national economic and strategic needs. Results show that other ore constituents and gangue materials in addition to uranium grade influence uranium extraction. In general, tailing grades decrease and uranium extraction increases as both h2so4 and nacio3 concentrations increase. Terminal emf and terminal ph also were studied. Similar trends appeared for all ores; however, specific combinations of results also were observed for individual ores and ore series. Experimental results indicate that uranium extractions are higher for lower uranium feed grades than predicted by other estimates.
