| Abstract: |
| The recovery of valuable elements from flotation tailings was conducted by a technical process consisting of regrinding of tailings, mix-flotation of lead-zinc ore and activated flotation of zinc. The results indicate that the recovery rates of lead and zinc in mixed concentrate were 36.4% and 18.0% respectively, the recovery of zinc in coarse concentrate was 57.6% in the open circuit experiment; Under the conditions that the grinding fineness of -0.074mm was accounted for 82%, Ethyl thiazide and butyl xanthate were selected as collectors for mix-flotation of lead and zinc, sodium sulfide and copper sulphate were used to activated zinc ore with butyl xanthate and isoamyl xanthate used as collectors. The valuable elements in the original flotation tailings could be effectively recovered. |
