Abstract

PROCESO PARA LA SEPARACION DE ORO, PLATA Y/O PALADIO, DEL COBRE Y OTROS METALES CONTAMINANTES, DONDE SE UTILIZA UNA MEMBRANA ADECUADA DE FILTRO, PREFERENTEMENTE UN NANOFILTRO, PARA FORMAR UN RETENTATO QUE CONTIENE LA MAYORIA DE LOS COMPLEJOS DE CIANURO DEL METAL POLIVALENTE. EL FILTRO CUENTA CON UNA CARGA ELECTRICA PARA REPELER EL COMPLEJO DE CIANURO DEL METAL POLIVALENTE DISUELTO Y PERMITIR EL PASO DEL COMPLEJO DE CIANURO DEL METAL PRECIOSO. FINALMENTE EL METAL PRECIOSO ES RECUPERADO POR MEDIO DE: CEMENTACION, AMALGAMACION, PRECIPITACION, INTERCAMBIO IONICO, ELECTROLISIS, ABSORCION Y ADSORCION
