Abstract

<p>SE DESCRIBE UN SISTEMA Y MÉTODO PARA MEJORAR LA CINÉTICA DE LA LIXIVIACIÓN Y LA RECUPERACIÓN DURANTE LA LIXIVIACIÓN ATMOSFÉRICA ANTERIOR DE UN SULFURO DE METAL. EN ALGUNAS MODALIDADES, EL MÉTODO PUEDE COMPRENDER LOS PASOS DE: (A) PRODUCIR UN CONCENTRADO DE SULFURO DE METAL (34) POR FLOTACIÓN; (B) MOVER EL CONCENTRADO DE SULFURO DE METAL PRODUCIDO (34) A POR LO MENOS UNA CÁMARA (22A) DE POR LO MENOS UN REACTOR TAL COMO UNA AUTOCLAVE (20); (C) LIXIVIAR EL CONCENTRADO DE SULFURO DE METAL PRODUCIDO EN POR LO MENOS UNA CÁMARA (22A) EN LA PRESENCIA DE OXIGENO (82) A UNA PRESIÓN Y/O TEMPERATURA SUPERIOR A LA AMBIENTE, Y EN LA PRESENCIA DE MEDIOS DE MOLIDO PARCIALMENTE UTILIZADOS (25) Y/O NUEVOS (92) DENTRO DE POR LO MENOS UNA CÁMARA (22A). TAMBIÉN SE DESCRIBEN SISTEMAS (10) Y UN APARATO (20, 200) PARA PRACTICAR EL MÉTODO ANTES MENCIONADO.</p>
