Description
The authors describe the features of some 70 samples of radioactive lignites from various places in Spain (Huesca, Lerida, Teruel, Galicia and Murcia) with uranium contents varying between 20 and 1200 ppm. They carried out experiments on extraction of the uranium from these ores both by direct treatment and after roasting to eliminate organic matter and bring about concentration. The acid method was considered for leaching of the uranium from the substances in question using agitation and static bed techniques. Investigations were also carried out on the effect of the variables represented by grain size, amount of acid, temperature time and oxidants, in addition to those involved in the roasting process.

Abstract (Spanish)
Los autores presentan las caracteristicas de unas 70 muestras de lignitos radiactivos procedentes de distintos puntos de Espana (Huesca, Lerida, Teruel, Galicia y Murcia) con leyes de uranio comprendidas entre 20 y 1200 ppm. El beneficio del uranio de estos minerales se ha abordado por tratamiento directo y despues de someterlos a tostacion, lo que elimino la materia organica y produjo enriquecimiento. La lixiviacion del uranio de los productos indicados se considero por via acida, utilizando tecnicas de agitacion y de lecho estatico. Se investigo la influencia de las variables tamano de grano, dosis de acido, temperatura, tiempo y oxidante, ademas de las implicadas en los procesos de tostacion. (author)Additional details
