Acid Mine Drainage

AMD occurs when sulphide minerals oxidize in exposed tailings and waste rock, producing acidic, metal-laden drainage.

Prevention

Covers (soil, clay, geosynthetic), flooding and alkaline amendment prevent oxygen ingress and AMD generation.

Active Treatment

Lime neutralization, chemical precipitation and reverse osmosis treat AMD to meet discharge standards.

Passive Treatment

Wetlands, anoxic limestone drains and bioreactors treat AMD with minimal operating cost for remote sites.
