Abstract

DONDE EL OTRO METAL SE SELECCIONA DE ALUMINIO, GRAFITO, SILICIO, TITANIO, CIRCONIO, HIERRO Y COBRE. LA RELACION, EN PESO, ENTRE LA MEZCLA DE ZINC Y DEL OTRO METAL ESTA EN EL RANGO DE 100:1 A 1:100, CONTENIENDO EL VEHICULO DE 2% A 80%, EN PESO, DE ZINC. EL ORO TIENE UN TAMANO DE PARTICULA INFERIOR A 100 NANOMETROS E INCLUYE ESPECIES DE ORO METALICO Y ESPECIES DE ORO POSITIVAMENTE CARGADAS, Y EL VEHICULO TIENE UN AREA SUPERFICIAL DE 4 A 180 m2/g. EL VEHICULO SE FORMA POR UNA TECNICA SELECCIONADA DE: PRECIPITACION, CO-PRECIPITACION, IMPREGNACION, OXIDACION DE VAPORES METALICOS Y MEZCLA FISICA DE OXIDO DE ZINC Y DICHO OXIDO METALICO. LA CO-PRECIPITACION INCLUYE: PREPARAR UNA SOLUCION ACUOSA CONTENIENDO, AL MENOS, UN COMPUESTO DE ORO SOLUBLE EN AGUA Y SALES SOLUBLES EN AGUA DE ZINC Y DEL OTRO METAL; DEPOSITAR ORO DESDE LA SOLUCION SOBRE UN VEHICULO DE ZINC Y DE OTRO METAL, LOS QUE PRECIPITAN DESDE LA SOLUCION, Y SEPARAR EL VEHICULO CONTENIENDO ORO DESDE LA SOLUCION; EXPONER EL VEHICULO CONTENIENDO ORO A UN AGENTE REDUCTOR PARA AUMENTAR LA ACTIVIDAD CATALITICA INICIAL DE ORO; Y, CALCINAR EL VEHICULO CONTENIENDO OROWHERE THE OTHER METAL IS SELECTED FROM ALUMINUM, GRAPHITE, SILICON, TITANIUM, ZIRCONIUM, IRON AND COPPER. THE RATIO, IN WEIGHT, BETWEEN THE MIXTURE OF ZINC AND THE OTHER METAL IS IN THE RANGE OF 100: 1 TO 1: 100, THE VEHICLE CONTAINING FROM 2% TO 80%, BY WEIGHT, OF ZINC. THE GOLD HAS A PARTICLE SIZE LESS THAN 100 NANOMETERS AND INCLUDES METALLIC GOLD SPECIES AND POSITIVELY CHARGED GOLD SPECIES, AND THE VEHICLE HAS A SURFACE AREA OF 4 TO 180 m2 / g. THE VEHICLE IS FORMED BY A SELECTED TECHNIQUE OF: PRECIPITATION, CO-PRECIPITATION, IMPREGNATION, OXIDATION OF METALLIC VAPORS AND PHYSICAL MIXTURE OF ZINC OXIDE AND SAID METALLIC OXIDE. CO-PRECIPITATION INCLUDES: PREPARING AN AQUEOUS SOLUTION CONTAINING, AT LEAST, A WATER-SOLUBLE GOLD COMPOUND AND WATER-SOLUBLE SALTS OF ZINC AND OTHER METAL; DEPOSIT GOLD FROM THE SOLUTION ONTO A VEHICLE MADE OF ZINC AND ANOTHER METAL, THOSE THAT PRECIPIT FROM THE SOLUTION, AND SEPARATE THE VEHICLE CONTAINING GOLD FROM THE SOLUTION; EXPOSE THE VEHICLE CONTAINING GOLD TO A REDUCING AGENT TO INCREASE THE INITIAL GOLD CATALYTIC ACTIVITY; AND, CALCINE THE VEHICLE CONTAINING GOLD
