Apr 22, 2021 From The Water Filter. Sulphuric Acid is used in iron mining. In nearly all metal mines, and some coal mines, acid drainage occurs because of the oxidation of iron ore found alongside precious mineral deposits. Uncovered by the mining process, the iron reacts with the air and releases sulphuric acid into the water. This process can last centuries.

Water Pollution From Coal Global Energy Monitor

Water Pollution From Coal Global Energy Monitor

Acid mine drainage (AMD) refers to the outflow of acidic water from coal or metal mines, often abandoned ones where ore- or coal mining activities have exposed rocks containing the sulphur-bearing mineral pyrite. Pyrite reacts with air and water to form sulphuric acid and dissolved iron, and as water washes through mines, this compound forms a dilute acid, which can wash into nearby rivers and.
