Question

Quizplus · Accepted Answer

Oxidation of pyrite and other sulphides, commonly found in association with various ores, leads to the production of sulfuric acid upon exposure to water and oxygen. This process, often referred to as "acid mine drainage," is a significant environmental hazard associated with mining activities, as it can lead to the acidification of nearby water bodies, killing aquatic life and damaging ecosystems.
