Abstract
Un metodo para extraer metales preciosos de una mena polimetalica, que comprende: a) generar hipocloritos a partir de una solucion salina; b) clorar la mena usando hipocloritos en condiciones acidas; e) filtrar para recolectar una solucion impregnada y tratar la solucion impregnada para recolectar los metales preciosos; d) filtrar para separar los metales preciosos de la solucion salina agotada; e) purificar la solucion salina agotada; y f) reciclar los halogenos de la solucion salina purificada en forma de hipohalitos formados por electrolisis de la solucion salina purificada, y que comprenden hipoclorito e hipobromito; donde el paso b) ademas comprende realizar una depuracion para eliminar el exceso de halogenos usando hidroxido de calcio; tratar la solucion impregnada en el paso c) comprende reducir un potencial de oxido-reduccion de la solucion impregnada y usar hidroxido de calcio para la neutralizacion; y el paso e) comprende aumentar el pH de la solucion salina agotada por agregado de hidroxido de calcioA method for extracting precious metals from a polymetallic ore, comprising: a) generating hypochlorites from a saline solution; b) chlorinate the ore using hypochlorites under acidic conditions; e) filtering to collect an impregnated solution and treating the impregnated solution to collect the precious metals; d) filtering to separate the precious metals from the spent saline solution; e) purifying the spent saline solution; and f) recycling the halogens from the purified saline solution in the form of hypohalites formed by electrolysis of the purified saline solution, and comprising hypochlorite and hypobromite; wherein step b) further comprises performing a scrubbing to remove excess halogens using calcium hydroxide; treating the impregnated solution in step c) comprises reducing an oxide-reducing potential of the impregnated solution and using calcium hydroxide for neutralization; and step e) comprises increasing the pH of the depleted saline solution by adding calcium hydroxide
