Abstract
QUE COMPRENDE: a) HACER REACCIONAR UNA SOLUCION DE TIOSULFATO AGOTADA CON SULFURO PARA PRODUCIR AZUFRE ELEMENTAL Y UNA SOLUCION DE TIOSULFATO REGENERADA; b) SEPARAR DE LA SOLUCION DE TIOSULFATO REGENERADA EL AZUFRE ELEMENTAL; c) REDUCIR BIOLOGICAMENTE EL AZUFRE ELEMENTAL SEPARADO PARA PRODUCIR SULFURO, EMPLEANDO HIDROGENO, ALCOHOL O ACIDO ORGANICO COMO DONADOR DE ELECTRONES; Y, d) RETORNAR EL SULFURO DE (c) A (a). LA SOLUCION DE TIOSULFATO REGENERADA RESULTANTE DE (b) TIENE UNA CONCENTRACION DE TIOSULFATO ENTRE 0,01 y 0,10 M. ADEMAS SE DESCRIBE UN PROCESO DE EXTRACCION DE METALES DESDE UNA SUSPENSION CON CONTENIDO DE METAL, QUE INCLUYE: PONER EN CONTACTO LA SUSPENSION CON UNA SOLUCION CONTENIENDO IONES DE TIOSULFATO Y OXIGENO PARA PRODUCIR UNA SOLUCION DE TIOSULFATO METALICO; SEPARAR EL METAL NOBLE DE LA SOLUCION DE TIOSULFATO METALICO AL PONER EN CONTACTO LA SOLUCION CON UN ABSORBENTE, EN PRESENCIA DE IONES COBRE, PRODUCIENDO UNA SOLUCION DE TIOSULFATO AGOTADA Y ABSORBENTE CARGADO CON METAL; Y REGENERAR LA SOLUCION DE TIOSULFATO AGOTADA MEDIANTE LOS PASOS (a) A (d). EL ABSORBENTE ES UNA RESINA DE INTERCAMBIO ANIONICO
