Static leaching of Spanish uranium ores; Lixiviacion estatica de minerales espanoles de uranio

Abstract

The paper summarizes the experience acquired in Spain during seven years of investigation on the static leaching of uranium ores. The operations covered minerals showing wide variations with regard to both uranium content (250 and 2000 ppm) and the type of rock and gangue (granites, shales, sandstones, sulphides, carbonates, limonites etc.). The studies were carried out on quantities of material varying from a few kilograms to several tons. Leaching agents included water, solid reagents (pyrites), alkaline carbonates and sulphuric acid. The systems used consisted of both simple layouts and other, more elaborate schemes including recycling of the liquors. The uranium was recovered from the liquors first by direct precipitation and later by ion-exchange and extraction with amines.

Los circuitos empleados se refieren tanto a esquemas sencillos, como a otros mas elaborados con recirculaciones de liquido. La recuperacion del uranio de los liquidos se resolvio inicialmente por precipitacion directa, pero luego se efectuo mediante cambio de ion y extraccion con aminas. (author)}
