ARD Risk Evaluation and Modelling

Acid Mine Drainage and heavy metal contaminant become the main problem in managing the mining environment. GES offers its expertise in developing an integrated mine waste management.

  • Rock Sampling : Representative rocks sampling plan and preparation depending on geological condition (stratigraphy and lithology) and mining plan.
  • Material Classification : Acid Mine Drainage and heavy metal leaching forming process prediction through mineralogy test, static (acid-base accounting) and kinetic/leaching tests.
  • Formation of geochemical rock distribution model as a mining plan baseline and waste rock pile design.
  • Cover system design and perfor-mance monitoring in waste rock pile.
