Overview

Randomized trial demonstrates efficient lead sulfide purification in complex ores, suggesting a viable industrial application.

Key Points

  • This research aims to develop a hybrid purification strategy to efficiently remove antimony sulfide from lead sulfide ores.
  • Mechanical ball milling to break Sb2S3 inclusions.
  • Anaerobic leaching in a sealed reactor with NaOH at pH 9-11.
  • Thermodynamic analysis using Eh-pH diagrams to identify selective dissolution conditions.
  • Antimony removal exceeded 99% with lead loss below 1%.
  • Zeta potential measurements indicated stable colloidal dispersion (−12.3 mV).
  • High conductivity (204 mS/cm) confirmed favorable conditions for interfacial reactions.
