Answer :
A serious environmental hazard, acid mine drainage is the result of the chemical weathering of pyrite that yields sulphuric acid and Iron oxide that will degrade aquatic habitats.
The severe problems that are associated with mine drainage problems include drinking water which is contaminated, disrupted type of growth and reproductive issues of aquatic plants and including animals, and those corroding effects caused by acids on parts of bridges which is a source of infrastructure.
Acid mine drainage is a serious issue occurred as a result of water contamination when pyrite or iron sulfide is made exposed to air and water as well. This exposure at last often results in several reactions that make the reason for evolving out sulfuric acid with dissolved iron.
Whenever pyrite or iron sulfide reacts with oxygen, it then releases the final chemical output called sulfuric acid, which is the main reason for causing acid mine drainage which is considered to be a serious environmental issue to happen across the globe.
