Treatment of Copper-separated Residue from Copper Anode Slime by Chlorination Leaching and Reduction AITranslate
Abstract AITranslate
Gold, selenium and tellurium were separated from copper-separated residue from copper anode slime by Chlorination leaching,and then the gold was selectively reduced from the leaching solution with ferrous sulfate. The results show that under the optimized conditions of leaching time of 150 min,leaching temperature of 60 ℃ ,sodium chlorate conentration of 65 g/L,the ratio of liquid to solid of 4 ： 1, sodium chloride concentration of 50 g/L, sulfuric acid concentration of 300 g/L, the leaching rates of gold, selenium and tellurium can reach 93.7%, 93.7% and 93.7%, respectively. It is feasible to reduce gold chloric acid from the chloridizing leaching solution with ferrous sulfate,and the reduction rate of gold is 99.7%. In the reduction product, gold exists as elemental gold, almost without elemental selenium, elemental tellurium and other impurities.
