Investigations on the nature and physical concentration of Spanish uraniferous quartzites; Estudios de caracterizacion y concentracion fisica de cuarcitas uraniferas espanolas

Abstract

A study was made of a sample of radioactive material from Santa Elena (Jaen) containing 130 ppm U{sub 3}O{sub 8}, 300 ppm ThO{sub 2}, 4.96% ZrO{sub 2} and 14.29% TiO{sub 2}. Over 150 million tons of material were examined. In the light of the studies carried out the material can be defined as a rutilo-zirconiferous quartzite with a double radioactivity source due to the uranium enclosed in the zircon lattice structure and to the presence of monazite. The possibility of brannerite or davidite being present can be discarded. There is likewise no conclusive evidence of the presence of sphene, rutile being the most abundant titanium mineral. The author determined the features of the ore with a view to its physical concentration and applied magnetic and gravimetric separation and the flotation process. The use of oleic acid as collector has permitted good zircon recovery.

El material examinado es considerable: mas de 150 millones de toneladas. De acuerdo con los estudios realizados se puede definir como una cuarcita rutilo-circonifera con dos fuentes de radiactividad debidas al uranio englobado en la red del circon y a la presencia de monacita. Se descarta la posibilidad de existencia de brannerita o davidita. Tampoco existen pruebas concluyentes de que contenga esfena, siendo el ratilo el mineral de titanio mas abundante. Se han determinado las caracteristicas de la mena con vistas a su concentracion fisica. Se ha ensayado la separacion magnetica, gravimetrica y flotacion. El empleo de acido oleico, como colector, ha dado buenas recuperaciones de circon. (author)}
