Abstract
This study investigates the kinetics and the mechanics of the reactions that produce acid in coal mine drainage using fresh mine face samples from five Appalachian coal mines. The results of the study show that pyrite weathering is based on oxidation in the presence of water where the oxidants can be either ferric iron or oxygen. Iron bacteria, especially t. Ferrooxidans, catalyze the rate of pyrite weathering by a factor of 3. An increase in initial iron concentration in a system that models the mine environment acts to inhibit bacterial catalysis of pyrite weathering.
