Abstract
Un procedimiento para la extracción de uranio de sus minerales ya sea directamente en el propio depósito de mineral o después de que el mineral ha sido separado del suelo, que comprende una fase de oxidación/lixiviación, en la que se utilizan soluciones de carbonato y bicarbonato de un metal alcalinotérreo para la lixiviación bajo presión de dióxido de carbono.A process for the extraction of uranium from its ores either directly in the ore deposit itself or after the ore has been separated from the ground, comprising an oxidation/leaching phase, in which solutions of carbonate and bicarbonate of an alkaline earth metal are used for leaching under carbon dioxide pressure.
