| Abstract: | The technological researches for recover elementary sulfur by distillation under normal pressure from sulfur residue after high- pressure acid leaching of sulfide zinc concentrate has been carried out and the influential factors for distillation were analyzed. The result shows that the elementary sulfur with the purity of above 98% can be produced by distillation process under normal pressure. The sulfur in distillation residue can be decreased to 24.48%, which is in the form of compounds. |
| Keywords: | distillation under normal pressure sulfur residue extraction elementary sulfur |
