| Abstract: |
| Encapsulation of sulfur is important factors in oxygen pressure leaching of sphalerites.It proves the effect of encapsulation of sulfur on zinc dissolution through contrast experiments,and explores initially the mechanism of the effect of sodium lignosulfonate on zinc dissolution,and the dose of sodium lignosulfonate under the premise of the high zinc dissolution rate. |
