| Abstract: |
| Ultrasound strengthening leaching on refractory copper oxide ore was studied. Copper leaching rate is 59.35% under the conditions including ultrasonic amplitude of 70% and leaching time of 15 min. Compared with conventional agitation leaching, ultrasound strengthening leaching process takes 1/8 leaching time with 4.95 percent point higher copper leaching rate. Total copper recovery is 90.91% through closed-circuit test of ultrasonic strengthening leaching on undressed ore and flotation for leaching slag. |
