Abstract

QUE COMPRENDE: a) LIXIVIAR UN MATERIAL MINERAL QUE CONTIENE METALES PRECIOSOS, CON UNA SOLUCION DE TIOCIANATO QUE COMPRENDE TIOCIANATO DISUELTO Y HIERRO FERRICO DISUELTO, PARA DISOLVER LOS METALES PRECIOSOS EN COMPLEJOS DE METALES PRECIOSOS-TIOCIANATO Y PARA REDUCIR EL HIERRO FERRICO DISUELTO EN HIERRO FERROSO DISUELTO; b) RECUPERAR AL MENOS UNA PORCION DE METALES PRECIOSOS DE LA SOLUCION DE LIXIVIACION, MEDIANTE CONTACTO CON UNA FASE DE EXTRACCION ORGANICA AL CUAL SE TRANSFIEREN LOS METALES PRECIOSOS O CON UNA RESINA DE INTERCAMBIO IONICO O CON CIANURO DISUELTO, COMPRENDIENDO EL EFLUENTE ESTERIL DE DICHA SOLUCION UNA CONCENTRACION DE HIERRO FERRICO DISUELTO MENOR A LA DE LA ALIMENTACION; Y, c) INCREMENTAR LA CONCENTRACION DE HIERRO FERRICO DISUELTO EN LA SOLUCION DE LIXIVIACION, CON RELACION A LA CONCENTRACION DE HIERRO FERRICO DISUELTO EN EL EFLUENTE ESTERIL, OXIDANDO EL HIERRO FERROSO A SU FORMA FERRICA CON PERSULFATO. LA SOLUCION DE LIXIVIACION SE MANTIENE EN UN pH ENTRE 1 Y 3 DURANTE EL PROCESO DE RECUPERACION, LA RELACION MOLAR DE HIERRO FERRICO DISUELTO A TIOCIANATO DISUELTO ES DE AL MENOS 2, Y LA CONCENTRACION DE TIOCIANATO DISUELTO EN LA SOLUCION NO ES MAYOR A 0,03 mol/L. LA FASE DE EXTRACCION ORGANICA INCLUYE UN AGENTE DE EXTRACCION QUE CONTIENE FOSFORO. ANTES DE LIXIVIAR SE PREPARA EL MATERIAL MINERAL FORMANDO UNA PILA QUE COMPRENDE MATERIAL PARTICULADO CON MINERALES SULFUROSOS, Y BIO-OXIDANDO DICHO MATERIAL PARA DESCOMPONER LOS MINERALES SULFUROSOS
