SERVICES: Quantitative Sulphide Deportment

Scope of the study, deliverables and methodology

  • Bulk Mineralogy including sulphide mineralogy and morphology study
  • Size by size modal mineralogy and global modal mineralogy
  • Size by size sulphide liberation and calculated sulphide liberation
  • Sulphides association with gangue minerals at different size fractions
  • Image grid of sulphide association and gangue minerals
  • Elemental S, As and Fe deportment analysis
  • SEM-EDS/Micro-probe compositional analysis of sulphides
  • Mineralogy Grade Recovery curve
