| titleOfInvention | Method for recovering gold by using adsorption resin |
| abstract | The invention belongs to the technical field of wet metallurgy, and discloses a method for recovering gold by using adsorption resin, which comprises the following steps: (S1) adjusting the pH value of the gold-containing leaching solution containing gold ions to 1-3, and then adding adsorption resin into the gold-containing leaching solution to adsorb the gold ions in the gold-containing leaching solution; the surface of the adsorption resin is provided with sulfur and nitrogen, and the contents of the nitrogen and the sulfur on the surface of the adsorption resin respectively account for more than 3 percent and more than 20 percent of the total mass of the adsorption resin; (S2) after the adsorption, the gold loaded on the adsorption resin obtained by the step (S1) is eluted, concentrated, separated and regenerated with an eluent, and the gold is recovered. The invention improves the key reaction participators of the method, applies the adsorption resin material with high sulfur element and nitrogen element content on the surface to the recovery of gold, and particularly can be applied to the recovery of gold in low-grade gold-containing materials. The method is simple to operate and suitable for large-scale recovery of low-concentration gold in the leaching solution. |
