Abstract

SE REFIERE A UN PROCESO PARA LA RECUPERACION DE ORO Y PLATA A PARTIR DE SOLUCIONES LIXIVIANTES DE TIOSULFATO O TIOUREA QUE CONTIENEN 0.2 MOL/L DE (NH4)2S2O3, 0.05 MOL/L DE CuSO4, 0.025 MOL/L DE EDTA Y 0.1 MOL/L DE (NH4)2HPO4, EN DONDE DICHO PROCESO SE REALIZA POR ELECTROLISIS MEDIANTE UN DEPOSITO METALICO SIMULTANEO EN LAS SUPERFICIES DEL CATODO Y DEL ANODO, TRABAJANDO EN LAS ZONAS DE POTENCIAL QUE PERMITEN LA REDUCCION DE LA PLATA EN EL CATODO Y LA OXIDACION DEL LIGANDO EN EL ANODOREFERS TO A PROCESS FOR THE RECOVERY OF GOLD AND SILVER FROM THIOSULPHATE OR THIOUREA LEACHING SOLUTIONS CONTAINING 0.2 MOL / L OF (NH4) 2S2O3, 0.05 MOL / L OF CuSO4, 0.025 MOL / L OF EDTA AND 0.1 MOL / L OF (NH4) 2HPO4, WHERE SAID PROCESS IS CARRIED OUT BY ELECTROLYSIS THROUGH A SIMULTANEOUS METALLIC DEPOSIT ON THE CATHODE AND ANODE SURFACES, WORKING IN THE POTENTIAL AREAS THAT ALLOW THE REDUCTION OF THE SILVER IN THE CATHODE AND THE LIGANDING OF THE OXIDE IN THE ANODE
