The presentation will discuss current practices to characterize mine rock mined materials for purposes of predicting acid rock drainage/metal leaching. Specific topics covered include:
- Overview of interrelationships between geochemical characterization, modeling, and mine management.
- Geochemical characterization approaches.
- Static tests - when to use and pros/cons of most common tests.
- Kinetic tests - when to use and pros/cons of most common tests.
- Interpretation and use of geochemical characterization data; method uncertainties.
- Resources available for further information on the topics covered.

Specific topics covered during this lecture include:
- Introduction to geochemical modeling: models, codes, prediction, modeling pyrite oxidation.
- Types of geochemical modeling: equilibrium speciation, mass transfer, reactive-transport, transient-state.
- Input data and output (GIGO): Thermodynamic, kinetic, and field data.
- Some examples and applications.
- Confidence in modeling results: issue of validation and verification.
- Modeling guidelines: Issues regulators should know and questions regulators should ask when reviewing modeling efforts.
