| Abstract: | The method of sulphur recovery from high - sulphur slurry in direct atmospheric leaching of zinc concentrate is intro- duced. The sulphur constitution in flashing process is changed, sulphur in hot - melting filtration is produced. It is a physical change, short process and simple equipment, easy operation and low production fee. It can solve the problem of sulphur recovery from high - sulphur slurry in direct atmospheric leaching of zinc concentrate and renovate the direct atmospheric leaching process. |
