How does acid water leak out of the mine?
Acidic water can leak out of mines when it comes into contact with exposed rocks containing sulfide minerals. Through a natural process called oxidation, these minerals react with water and oxygen to produce sulfuric acid, which then flows out of the mine along with other dissolved metals. This acidic water can have negative impacts on the surrounding environment by contaminating water sources and harming aquatic life.
What water is not neutral?
Water that has been contaminated with impurities like chemicals, minerals, or pollutants can become acidic or basic, meaning it is no longer neutral. Additionally, naturally occurring bodies of water, such as acid mine drainage or alkaline lakes, can also be non-neutral.
Does coal react with acid?
Yes, coal itself is largely inert and does not react with acids due to its high carbon content. However, some impurities in coal, such as sulfur compounds, may react with acids to release sulfuric acid, which can lead to acid mine drainage when coal is exposed to air and water.
What forms when water carries sulfur from coal in a solution?
When water carries sulfur from coal in a solution, it can create acid mine drainage (AMD). AMD is formed when the sulfur reacts with oxygen and water, producing sulfuric acid. This acidic solution can leach out heavy metals from rocks, resulting in environmental pollution.
Coal is to oil just as mine is to?
Coal is to oil as mine is to minerals. Both coal and oil are fossil fuels extracted from the earth, just as minerals are extracted from mines.

What kind of mining practices can result in acid mine drainage?
Mining practices such as open-pit mining, mountaintop removal mining, and underground mining can result in acid mine drainage when sulfide-containing minerals are exposed to air and water, leading to the formation of sulfuric acid. When the acidic water flows out of the mine, it can contaminate nearby water sources and harm aquatic life. Mitigation measures such as neutralization and containment are often implemented to prevent acid mine drainage.

Science in acid mine runoff?
Acid mine runoff is a major environmental issue caused by the oxidation of sulfide minerals in abandoned mines, leading to the release of acidic and metal-rich water. Scientists study the geochemical processes involved in acid mine runoff to understand its impact on water quality, ecosystems, and human health. Research focuses on developing remediation strategies such as neutralization, passive treatment systems, and reclamation to mitigate the effects of acid mine drainage.

What is mining water?
Acid mine drainage is the low pH created by microorganisms convering sulfides and sulfates in tailing from the ore processing into sulfuric acid.

Is decomposition of pyrite an important factor in generating acidic mine drainage?
Yes the sulphur in the pyrite makes sulphuric acid.
