| Abstract: |
| A new process to leach gold from copper-bearing gold refractory ore was put forward. Copper was inhibited with depressant (MZY) and gold was selectively cyaniding leached. The technical parameters were optimized. The results show that the leaching rate of gold and copper is 83%~84% and 4%~5% respectively when the dosage of lime, MZY and sodium cyanide is 18, 0.5 and 1.2 kg/t respectively. The new process has the advantages of high gold leaching rate, good copper inhibitory effect, and easy operation. |
