Acid mine drainage: Challenges and opportunities

2014-9-1  Effects of acid mine drainage. As can be seen from the previous section, the oxidation of sulphidic minerals (such as pyrite) promotes the creation of sulphuric acid which subsequently promotes the release of a whole range of metals. As a result, AMD contains high concentrations of acid and dissolved metals.

The story of Rum Jungle: a Cold War-era uranium

2021-5-24  The waste rock and tailings (processed ore) at Rum Jungle contains significant amounts of iron sulfide, called “pyrite”. When mining exposes the pyrite to water and oxygen, a chemical reaction occurs generating so-called “acidic mine drainage”. This drainage is rich in acid, salts, heavy metals and radioactive material (radionuclides), such as copper, zinc and uranium.

Understanding Soil Risks and Hazards USDA

Iron sulfide minerals (e.g., pyrite) commonly form in anaerobic soils and sediments in estuarine environments and tidal marshes by a process called sulfidization. During the active process, hydrogen sulfide gas, H 2 S, evolves. The rotten egg smell is positive identification in tidal environments. In geologic deposits on uplands, however, H 2
