Abstract

PROCEDIMIENTO DE RECUPERACION GLOBAL DE URANIO, YTRIO, TORIO Y TIERRAS RARAS CONTENIDOS EN UN MINERAL FOSFATADO.CONSISTE EN INTRODUCIR ALUMINIO Y/O HIERRO AL LLEVAR A CABO EL ATAQUE ACIDO DEL MINERAL. EL ALUMINIO SE INTRODUCE EN FORMA DE SULFATO, FOSFATO O ALUMINA. EL HIERRO SE INTRODUCE EN FORMA DE SULFATO, FOSFATO O ALUMINA, O UN OXIDO TAL COMO OXIDO FERRICO. EL ALUMINIO SE AÑADE EN UNA CANTIDAD QUE VARIA ENTRE 0,8 Y 1,5 EN PESO, EXPRESADO EN AL2O3, CON RESPECTO AL MINERAL SOMETIDO AL ATAQUE Y EL HIERRO SE AÑADE EN UNA CANTIDAD EXPRESADA ENFE2O3 QUE VENIA ENTRE 0,8 Y 1,5 EN PESO. AMBOS ELEMENTOS SE PUEDEN AÑADIR CONJUNTAMENTE EN EL ATAQUE EN FORMA DE UN SULFATO O UN OXIDO, TAL COMO UN OXIDO FERRICO. EL ATAQUE SE REALIZA EN PRESENCIA DE SILICE O ALUMINIO Y SILICE.
