| Abstract: |
| Gold-bearing filtrate was treated by iron powder reduction to recover Au, Ag and Cu. The effects of iron powder dosage, reduction time, and reduction temperature on reduction ratio of metals were investigated. The results show that Au, Ag and Cu content in gold-bearing filtrate drops from 2.4, 53 and 950 mg/L to 0.05, 0.4 and 7 mg/L, respectively, and Au, Ag and Cu content in filter cake is 386.8 g/t, 5 521.7 g/t, and 29.8%, respectively under the optimum conditions including iron powder dosage of 5 kg/m3, reduction temperature of 40 ℃, and reduction time of 30 min. |
