Top processes
- Pyrite is exposed to Oxygen when drainage lowers the water table or sulfidic sediment is excavated
- Oxygen oxidises pyrite: Fe2+ and sulfate are released, giving about 2 mol H+ per mol FeS2 before Fe2+ is oxidised
- Fe3+ attacks pyrite directly, 10 to 100 times faster than Oxygen, making more Fe2+ and acid
