Abstract | The present invention provides a method of recovering gold, and optionally silver, from gold-bearing, and optionally silver-bearing, double refractory raw material, comprising the steps of (a) leaching the said gold-bearing, and optionally silver-bearing, double refractory raw material in a chloride containing leaching solution to dissolve gold and to obtain a leach solution comprising gold, and optionally silver, in solution, whereby the redox of leaching solution in the chloride leaching step is above 550 mV vs. Ag/AgCl; and simultaneously contacting the said leach solution comprising gold, and optionally silver, in solution with a re-sorptive material to obtain a gold-containing, and optionally silver-containing, re-sorptive material; and (b) recovering gold and optionally silver from the said gold-containing, and optionally silver- containing, re-sorptive material. |
