Abstract

LA PRESENTE INVENCIÓN SE REFIERE A UN PROCESO PARA EL TRATAMIENTO DE<br /> CONCENTRADOS SULFURADOS DE COBRE, TAL COMO LA CALCOPIRITA, EL QUE SE<br /> REALIZA EN UNA CELDA CONFORMADA POR PAREDES Y UN PISO, EN CUYO<br /> INTERIOR EXISTE AL MENOS DOS CÁMARAS; UNA PRIMERA CÁMARA ANÓDICA CON<br /> UN ÁNODO Y UNA PRIMERA MEMBRANA; UNA SEGUNDA CÁMARA CATÓDICA CON<br /> UN CÁTODO Y UNA SEGUNDA MEMBRANA, EN DONDE DICHO PROCESO<br /> COMPRENDE LAS SIGUIENTES ETAPAS: A) PREPARAR EL ELECTROLITO FUERA DE<br /> DICHAS CÁMARAS, MEDIANTE UNA COMBINACIÓN DE LOS ÁCIDOS SULFÚRICO Y<br /> CLORHIDRICO CON AGUA; B) CARGAR LA PRIMERA CÁMARA ANÓDICA Y SEGUNDA<br /> CÁMARA CATÓDICA CON EL ELECTROLITO PREPARADO EN LA ETAPA A}; C) CARGAR EL<br /> CONCENTRADO DE SULFUROS DE COBRE EN LA CÁMARA ANÓDICA; D) AGITAR EL<br /> ANOLITO MEZCLADO CON LA CALCOPIRITA; E) CONECTAR LOS ELECTRODOS DE LA<br /> CELDA A LA FUENTE DE ENERGIA ELÉCTRICA PARA GENERAR CLORO EN EL ÁNODO;<br /> F1) GENERAR EN LA CÁMARA ANÓDICA ONDAS ULTRASÓNICAS PARA DESTRUIR LA<br /> CAPA DE AZUFRE QUE CUBRE LAS PARTICULAS DE CALCOPIRITA, MEJORANDO<br /> SIGNIFICATIVAMENTE LA VELOCIDAD DE LA LIXIVIACIÓN; F2) SIMULTÁNEAMENTE EN<br /> LA CÁMARA CATÓDICA SE ELECTRODEPOSITA COBRE METÁLICO PROVENIENTE DEL<br /> COBRE LIXIVIADO DE LA CÁMARA ANÓDICA; G) AJUSTAR EL POTENCIAL ELÉCTRICO DE<br /> LA CELDA PARA QUE SE PRODUZCA LA DEPOSITACIÓN DEL COBRE, EVITANDO<br /> ALGUNAS REACCIONES INDESEABLES DE REDUCCIÓN DE OTRAS ESPECIES<br /> IÓNICAS PRESENTES EN LA SOLUCIÓN; H) AJUSTAR LA TEMPERATURA ALREDEDOR DE<br /> LOS 50°C; I) ALIMENTAR CONTINUAMENTE EL ANOLITO DE LA CELDA CON<br /> CONCENTRADO DE SULFUROS DE COBRE Y AGUA, DE TAL FORMA QUE SE GENEREN<br /> CONTINUAMENTE LAS ESPECIES HCI, H2SO4, FESO4 Y CUSO4, EXISTIENDO<br /> TODAS ESTAS DISUELTAS EN FORMA IÓNICA; Y J) RETIRAR CONTINUAMENTE<br /> SOLUCIÓN DE CATOLITO DESDE LA CÁMARA CATÓDICA. ADEMÁS, LA PRESENTE<br /> INVENCION SE REFIERE A LA CELDA PARA REALIZAR DICHO PROCESO.<br />  THE PRESENT INVENTION REFERS TO A PROCESS FOR THE TREATMENT OF <br /> SULFURED COPPER CONCENTRATES, SUCH AS CALCOPIRITA, WHICH IS MADE IN A CELL CONFORMED BY WALLS AND A FLOOR, IN WHOSE <br /> INTERIOR EXISTS AT LEAST TWO CHAMBERS; A FIRST ANODIC CAMERA WITH AN ANODE AND A FIRST MEMBRANE; A SECOND CATHODIC CAMERA WITH <br /> A CATHODE AND A SECOND MEMBRANE, WHERE SUCH PROCESS <br /> UNDERSTAND THE FOLLOWING STAGES: A) PREPARE THE ELECTROLYTE OUT OF <br /> SUCH CAMERAS, BY A COMBINATION OF THE ACID AND <br /> CHLORHYDRIC WITH WATER; B) LOAD THE FIRST ANODIC AND SECOND CHAMBER <br /> CATHODIC CAMERA WITH THE ELECTROLYTE PREPARED IN STAGE A}; C) LOAD THE CONCENTRATE OF COPPER SULFURES IN THE ANODIC CHAMBER; D) SHAKE THE ANOLYTE MIXED WITH THE CALCOPIRITA; E) CONNECT THE ELECTRODES OF THE <br /> CELL TO THE ELECTRICAL ENERGY SOURCE TO GENERATE CHLORINE IN THE ANODE; <br /> F1) GENERATE IN THE ANODIC CAMERA ULTRASONIC WAVES TO DESTROY THE <br /> COAT OF SULFUR COVERING THE PARTICLES OF CALCOPIRITA, IMPROVING SIGNIFICANTLY THE SPEED OF LIXIVIATION; F2) SIMULTANEOUSLY IN <br /> THE CATHODIC CHAMBER IS ELECTRODEPOSITE METALLIC COPPER FROM THE <br /> LEAKED COPPER OF THE ANODIC CHAMBER; G) ADJUST THE ELECTRICAL POTENTIAL OF THE CELL SO THAT THE COPPER DEPOSITATION IS PRODUCED, PREVENTING <br /> SOME INDESEABLE REACTIONS OF REDUCTION OF OTHER SPECIES <br /> IONICS PRESENT IN THE SOLUTION; H) ADJUST THE TEMPERATURE AROUND <br /> 50 ° C; I) CONTINUOUSLY FEEDING THE CELL ANOLYTE WITH <br /> CONCENTRATE OF COPPER AND WATER SULFURES, SO THAT THEY ARE GENERATED <br /> CONTINUOUSLY THE SPECIES HCI, H2SO4, FESO4 AND CUSO4, THERE ARE ALL <br /> DISSOLVED IN IONIC FORM; AND J) CONTINUOUSLY REMOVE <br /> CATHOLIT SOLUTION FROM THE CATHODIC CHAMBER. IN ADDITION, THIS INVENTION REFERS TO THE CELL TO PERFORM SUCH PROCESS. <br />
