| Abstract: |
| Effect factors,such as ore size,leaching temperature,leaching time,alkali concentration and liquor to solid ratio(L/S),were studied to check the impact of leaching efficiency of zinc and its concomitant metals from zinc oxide ore with high silicon in the alkali solution.The results show that ore size affected little on it.With the increasing of alkali concentration,leaching efficiency of zinc and aluminium increased remarkably,but that of Pb and Cd increased slowly and Fe can't almost be leached.With the in... |
