| Abstract: |
| The cyaniding tailing of refractory gold ore was leached with thiourea process. The results show that the extraction rate of gold can reach 82.30% on the conditions including ratio of liquid to solid of 3∶1, pH of 1~1.5, thiourea concentration of 2 kg/t, temperature of 60 ℃ and leaching time of 6 h. |
