Abstract
UN PROCESO PARA LA LIXIVIACIÓN DE UN MATERIAL MINERAL PARTICULADO QUE COMPRENDE LOS PASOS DE ALIMENTAR EL MATERIAL MINERAL PARTICULADO A UN PASO DE LIXIVIACIÓN (10) EN EL CUAL SE LIXIVIA POR LO MENOS UN METAL VALIOSO PRESENTE EN EL MATERIAL MINERAL PARTICULADO PARA OBTENER UNA SOLUCIÓN DE LIXIVIACIÓN PARA FORMAR UN LICOR DE LIXIVIACIÓN CARGADO Y UN RESIDUO SÓLIDO QUE CONTIENE MATERIA MINERAL SIN DISOLVER, DONDE EL PASO DE LIXIVIACIÓN SE REALIZA EN CONDICIONES TALES QUE EN DICHO PASO DE LIXIVIACIÓN SE FORMA AZUFRE ELEMENTAL, DONDE EN EL PASO DE LIXIVIACIÓN SE AGREGAN CUENTAS O PARTÍCULAS QUE CAPTAN AZUFRE ELEMENTAL DE MANERA TAL QUE LAS CUENTAS O PARTÍCULAS TOMAN EL AZUFRE ELEMENTAL O LO RECOGEN; Y SEPARAR LAS CUENTAS O PARTÍCULAS DEL LICOR DE LIXIVIACIÓN CARGADO Y EL RESIDUO SÓLIDO. LAS CUENTAS O PARTÍCULAS SE PUEDEN TRATAR PARA ELIMINAR EL AZUFRE Y LAS CUENTAS O PARTÍCULAS SE ENVÍAN DE RETORNO AL PASO DE LIXIVIACIÓN. COMO ALTERNATIVA, NO ES NECESARIO QUE EL MINERAL COMPRENDA UN COMPONENTE SOLUBLE Y PUEDE SER UN SULFURO DE HIERRO Y/O ARSÉNICO REFRACTARIO QUE CONTIENE METALES PRECIOSOS QUE REQUIERE SU OXIDACIÓN ANTES DE SOMETERLO CORRIENTE ABAJO A PROCESOS CONVENCIONALES TALES COMO UNA CIANURACIÓN.
