Abstract

SE REFIERE A UN METODO PARA LA PREPARACION DE UN CONCENTRADO DE COBRE APROPIADO PARA TRATAMIENTO PIROMETALURGICO A PARTIR DE UN CONCENTRADO EN EL CUAL SE ENCUENTRA PRESENTE EL ZINC EN FORMA DE IMPUREZA. EL ZINC ES REMOVIDO DEL CONCENTRADO LIXIVIANDO EL CONCENTRADO CON UNA SOLUCION QUE CONTIENE ACIDO SULFURICO A PRESION Y TEMPERATURA ATMOSFERICA EN PRIMER LUGAR EN CONDICIONES DE OXIDACION, DE MODO QUE, ANTES DEL FINAL DE LA LIXIVIACION UN AGENTE DE REDUCCION ES ALIMENTADO EN LA ETAPA DE LIXIVIACION PARA PRECIPITAR EL COBRE DISUELTO. AL FINAL DE LA ETAPA DE LIXIVIACION LA CONCENTRACION DE ACIDO SULFURICO SE REGULA AL ORDEN DE 0 - 100 g/L PREFERENTEMENTE 5 - 25 g/LREFERS TO A METHOD FOR THE PREPARATION OF A COPPER CONCENTRATE SUITABLE FOR PYROMETALLURGICAL TREATMENT FROM A CONCENTRATE IN WHICH ZINC IS PRESENT IN THE FORM OF IMPURITY. THE ZINC IS REMOVED FROM THE CONCENTRATE LEACHING THE CONCENTRATE WITH A SOLUTION CONTAINING SULFURIC ACID AT ATMOSPHERIC PRESSURE AND TEMPERATURE IN THE FIRST PLACE IN OXIDIZING CONDITIONS, SO THAT, BEFORE THE END OF THE LEACHING, THE LEACHING AGENT IS ALLOWED IN A REDUCTION LEACHING AGENT TO PRECIPITATE THE DISSOLVED COPPER. AT THE END OF THE LEACHING STAGE THE CONCENTRATION OF SULFURIC ACID IS REGULATED TO THE ORDER OF 0 - 100 g / L, PREFERABLY 5 - 25 g / L
