Abstract

QUE COMPRENDE: a) PREPARAR UNA SOLUCION DE HALURO ACUOSA ACIDICA QUE TIENE UN POTENCIAL DE OXIDACION SUFICIENTE PARA OXIDAR EL MATERIAL SULFIDICO Y HACER QUE EL METAL PRECIOSO SEA SOLUBLE EN LA SOLUCION; b) AGREGAR EL MATERIAL A LA SOLUCION DE HALURO DE MODO QUE EL MATERIAL SULFIDICO SE OXIDE Y EL METAL PRECIOSO SE SOLUBILICE; c) SEPARAR DEL MATERIAL SULFIDICO OXIDADO LA SOLUCION QUE CONTIENE EL METAL PRECIOSO, MEDIANTE SEPARACION SOLIDO-LIQUIDO; Y, d) RECUPERAR EL METAL PRECIOSO DE LA SOLUCION MEDIANTE ADSORCION CON CARBON ACTIVADO EN UNA COLUMNA O MAS QUE CONTIENE(N) CARBONO, LUEGO DEL CUAL EL CARBONO SE ELUYE CON UNA SOLUCION DE CIANURO Y EL PRODUCTO ELUIDO SE PASA A UNA FASE DE ELECTROLISIS PARA LA RECUPERACION DEL METAL PRECIOSO. EL METAL PRECIOSO ES ORO, PLATA, PLATINO U OTRO METAL DEL GRUPO DE PLATINO; Y LA SOLUCION DE HALURO ACUOSO ES UNA DE HALURO DE METAL SOLUBLE SIENDO EL METAL COBRE Y/O HIERRO. UN SURFACTANTE TAL COMO UN SOLVENTE ORGANICO O MAS, INCLUYENDO KEROSENE O UN ETER FENOLICO, SE AGREGA A LA SOLUCION DURANTE LA OXIDACION PARA PREVENIR QUE EL METAL PRECIOSO SE ADSORBA AL CARBONO. ADEMAS SE DESCRIBE UN PROCESO PARA RETIRAR UN CONTAMINANTE DE UN MATERIAL SULFIDICO CONTAMINADO, QUE INCLUYE: i) MEZCLAR EL MATERIAL EN UNA SOLUCION ACUOSA EN DONDE UNA ESPECIE MULTIVALENTE DE UN ESTADO DE OXIDACION ALTO OXIDA EL CONTAMINANTE, REDUCIENDO SU ESTADO DE OXIDACION; Y, ii) RETIRAR EL CONTAMINANTE DE LA SOLUCION MIENTRAS SE REGENERA DICHA ESPECIE
