Abstract

QUE COMPRENDE: A) PROPORCIONAR UNA SOLUCION ACUOSA DE LIXIVIACION DE TIOSULFATO AMONIACAL, QUE CONTIENE A LOS METALES; B) FORMAR UN COMPLEJO DE TIOSULFATO AMONIACAL CON EL REACTIVO DE EXTRACCION CONTENIDO EN UN SOLVENTE ORGANICO INMISCIBLE EN AGUA (COMO KEROSENE), EXTRAYENDO ASI DICHOS METALES; C) SEPARAR CON UNA SOLUCION CAUSTICA DE pH 11, LOS METALES PRECIOSOS DESDE EL REACTIVO DE EXTRACCION; Y D) RECUPERAR EL METAL PRECIOSO DESDE LA SOLUCION ACUOSA DE SEPARACION, MEDIANTE ELECTROLISIS; SIENDO EL REACTIVO DE EXTRACCION: 1) UN COMPUESTO CON FUNCIONALIDAD DE GUANIDINA DE FORMULA R1R2N-(C=NR5)-NR3R4, EN DONDE DE R1 A R5 SON H, UN SUSTENTO DE RESINA DE INTERCAMBIO IONICO o GRUPOS AROMATICOS Y ALIFATICOS DE HASTA 25 ATOMOS DE CARBONO, LOS CUALES TIENEN UN pKa>12 A 25�C, EN DONDE: PARA EL SISTEMA DE EXTRACCION LIQUIDO/LIQUIDO SE PREFIERE N.N`-BIS(CICLOHEXIL).N"-ISOTRIDECIL GUANIDINA Y PARA EL SISTEMA DE EXTRACCION LIQUIDO/SOLIDO ESTA UNIDA A UNO DE R1 A R5, o 2) AMINA CUATERNARIA MEZCLADA CON UN ACIDO ORGANICO DEBIL, DE PREFERENCIA, CLORURO DE TRIMETIL AMONIO (C8-C10) MEZCLADO CON UN FENOL. DICHO PROCEDIMIENTO PERMITE LA RECUPERACION DE METALES PRECIOSOS PROVENIENTES DE MENAS QUE CONTIENE OTROS METALES PRECIOSOS, TALES COMO ORO Y PLATA QUE INTERFIEREN EN SU RECUPERACION
