Seminar

Acid rock drainage (ARD) and the associated process of metal leaching (ML) can be important issues at any construction project where rock is exposed to flowing water. This seminar will provide an introduction to the methods available to predict the reactivity of rock and the chemistry of drainage in contact with rock, and the use of the results to identify technologies to address ML/ARD. The seminar will appeal primarily to engineers and geoscientists working in the mining, transportation and utility industries. The following topics will also be covered:

• Why is this topic important?
• Overview of regulatory setting in British Columbia
• Brief chemistry background (pH, acidity, metals and other potential contaminants)
• Relevant geological and mineralogical background
• Description and origin of metal leaching and acid rock drainage (ML/ARD)
• Concepts for mitigation of ML/ARD
• Overall approach to prediction of ML/ARD
• Designing a prediction program
• Prediction tools
• Interpreting prediction data
• Hands-on opportunities to examine rock and mineral samples
