Pyrite Oxidation

Pyrite oxidation occurs when pyrite, a common iron sulfide mineral, reacts with oxygen and water. This process produces sulfuric acid and releases iron ions into the environment. It often happens when pyrite is exposed at the Earth's surface, such as in mining areas or exposed rock formations. The resulting acid can lead to environmental issues like acid mine drainage, which harms ecosystems and contaminates water sources. Chemically, pyrite reacts to form sulfuric acid and iron oxides, making the process a significant factor in geochemical cycles and environmental management.
