Abstract
DONDE LA RECUPERACION COMPRENDE: a) AGREGAR Cu(I) A LA SOLUCION PARA CEMENTAR POR UN PERIODO DE HASTA 2 HORAS Ag(I) Y FORMAR UNA SUSPENSION; b) ANTES O DURANTE EL PASO (a), AJUSTAR EL pH DE LA SOLUCION A UN VALOR ENTRE 0,1 Y 5; c) RECUPERAR Ag COMO CEMENTO DE Ag, POR SEPARACION LIQUIDO/SOLIDO DESDE LA SUSPENSION; d) DIVIDIR LA SOLUCION FORMADA EN (c) EN DOS CORRIENTES Y REMOVER LAS IMPUREZAS; e) REMOVER Cu DE UNA DE LAS CORRIENTES, USANDO SULFURO PARA PRECIPITAR Cu COMO CuS; f) REDUCIR Cu(II) A Cu(I) DE LA OTRA CORRIENTE, Y CLARIFICAR POR SEPARACION SOLIDO/LIQUIDO ESTA CORRIENTE POR REMOCION DE Cu METALICO AL PASO (f); g) USAR LA CORRIENTE CLARIFICADA PARA PROVEER Cu(I) AL PASO (a). LA SOLUCION DE SALMUERA ACIDA SE FORMA LIXIVIANDO CON SALMUERA UN RESIDUO DE BIO-LIXIVIACION CONTENIENDO Ag Y Cu, ESTANDO A UNA TEMPERATURA ENTRE LA AMBIENTAL Y 50°C, Y EN UNA ATMOSFERA NO OXIDANTEWHERE THE RECOVERY INCLUDES: a) ADD Cu (I) TO THE SOLUTION TO CEMENT FOR A PERIOD OF UP TO 2 HOURS Ag (I) AND FORM A SUSPENSION; b) BEFORE OR DURING STEP (a), ADJUST THE pH OF THE SOLUTION TO A VALUE BETWEEN 0.1 AND 5; c) RECOVER Ag AS AG CEMENT, BY LIQUID / SOLID SEPARATION FROM THE SUSPENSION; d) DIVIDE THE SOLUTION FORMED IN (c) INTO TWO CURRENTS AND REMOVE THE IMPURITIES; e) REMOVE Cu FROM ONE OF THE CURRENTS, USING SULFIDE TO PRECIPITATE Cu AS CuS; f) REDUCE Cu (II) TO Cu (I) FROM THE OTHER CURRENT, AND CLARIFY BY SOLID / LIQUID SEPARATION THIS CURRENT BY REMOVAL OF METALLIC Cu AT THE STEP (f); g) USE THE CLARIFIED CURRENT TO PROVIDE Cu (I) TO THE STEP (a). THE ACID BRINE SOLUTION IS FORMED BY LEACHING WITH BRINE A BIO-LEACHING RESIDUE CONTAINING Ag AND Cu, BEING AT A TEMPERATURE BETWEEN AMBIENT AND 50 ° C, AND IN A NON-OXIDIZING ATMOSPHERE
