| Abstract: |
| For a certain refractory Cu-Zn ore,a new process of bulk flotation-oxidizing roasting-selective leaching-Cu-Zn electrowinning is proposed.Laboratory and pilot-plant-scale tests have been conducted and satisfactory results are achieved.With this process,over-all recoveries for bulk flotation of copper and zinc are increased by 2.4% and 44.8% respectively as compared with using original process and the recoveries of copper and zinc from blended concentrate to production of 1~# cathode copper and zinc are over 92.5%.In addition,such valuable metals as cadmium,cobalt and silver can be recovered and the acid from Cu-Zn electrowinning or solvent extraction can be recycled. |
