| Abstract: |
| Oxidizing roasting and cyanidation leaching process were adopted to treat carbonaceous bearing gold ore from Shaanxi province. The optimum roasting condition is 680 ℃ for 2 h. The optimum cyanidation leaching conditions include concentration of NaCN of 1 000 g/t, leaching time of 24 h, and particle of roasted product of -0.074mm 90%. Under those conditions, leaching rate of gold is 86.91%, adsorption rate of gold is high and the limited step is leaching by CIP (Carbon in Pulp) method. |
