| Abstract: |
| Study on extraction of gold and silver from gold-extraction residue with the process of high temperature chloridization was conducted. The results indicate that the volatilization rate of gold and silver is 95.19% and 59.26%, respectively, under the conditions including adopt dry type mixing and powdered roasting, chloridization volatilization temperature of 1 000 ℃, chloridization time of 30 min, and the consumption of CaCl2 of 5%. |
