| Abstract: | Chlorination leaching and adsorption of gold on high-pressure oxidation residue of a domestic refractory gold concentrate were investigated.The results show that the gold leaching rate is 96.5% under the optimum conditions including sodium hypochlorite concentration of 10 g/L,pH=4,sodium chloride concentration of 75 g/L,temperature of 40 ℃,ratio of liquid to solid of 3∶1,stirring speed of 300 r/min and time of 120 min.The gold absorption rate is 99.2% when the above gold leaching solution is absorbed with 1 g/L 717 anion exchange resin at room temperature for 30 min.This process is simple,rapid with less pollution. |
