| Abstract: |
| Dearsenization pretreatment of refractory gold ore with high arsenic and sulfur bearing was conducted in argon atmosphere at high temperature. The effects of desulfurization temperature, time and oxygen flow rate on gold leaching rate with aqueous chlorate solution were investigated with dearsenization sample as raw materials. The results show that gold leaching rate is 95% above under the conditions of desulfurization temperature of 650 ℃, oxygen flow rate of 200 mL/min, and duration of 2 h. |
