Abstract

Procedimiento para la separación selectiva y obtención de plata y oro de soluciones predominantemente clorídicasque como componentes principales contiene otros metales pesadoscaracterizado porque en una primera etapa la solución clorídica se sometea un pH en el que no se pueden formar productos de hidrólisisa un tratamiento de tres etapasdonde en la primer etapaconforme a la concentración de orose agrega carbón activo finamente repartidoen la segunda etapa se dosifica un agente reductor para ajustar un potencial adecuado de ioduro a una temperatura en la que la solubilidad del producto de precipitación que contiene metales noblesque se formasea suficientemente bajaa continuación se agita la suspensión y de la solución clorídica se separan los metales nobles selectivamente precipitados con respecto a los iones de metal presentesjunto con el carbón activo yfinalmentedespués de secareste producto de precipitaciónse mezcla un ligador de ioduro adecuado y el producto de precipitación se funde en forma reductoracomo es conocidoobteniéndose un régulo de metal noble.
