Acid Rock Drainage / Metal Leaching Testing & Evaluation

Metro Testing + Engineering’s Acid Rock Drainage services address the suitability of aggregate and mineral ore for construction use by examining the material’s leachable content after subjecting it to standardized bench-scale laboratory tests. These tests simulate long-term weathering from precipitation and moisture to determine if the material will react with water to leach harmful contaminants to the environment, or cause structural and cosmetic issues such as accelerated corrosion or staining.

 

  • Evaluation and testing for acid rock drainage and metal leaching
  • Static testing and acid-base accounting (ABA) analysis
  • Analysis of whole rock for paste pH, total sulphur, and sulphide sulphur
  • Humidity analysis under controlled conditions using spectroscopy
