What is the primary environmental concern associated with mining activities?

  1. Air pollution

  2. Water pollution

  3. Land degradation

  4. All of the above


Correct Option: D
Explanation:

Mining activities can result in air pollution from dust and emissions, water pollution from contaminated runoff, and land degradation from the removal of vegetation and soil.

Which type of mining is known for causing significant land degradation and habitat loss?

  1. Surface mining

  2. Underground mining

  3. Open-pit mining

  4. Placer mining


Correct Option: C
Explanation:

Open-pit mining involves the removal of large amounts of soil and rock to expose mineral deposits, resulting in extensive land degradation and habitat loss.

What is the term used to describe the process of extracting minerals from ores?

  1. Beneficiation

  2. Smelting

  3. Refining

  4. Tailings disposal


Correct Option: A
Explanation:

Beneficiation is the process of separating valuable minerals from waste materials in ores, typically involving crushing, grinding, and flotation techniques.

Which mining method is considered to be the most environmentally friendly?

  1. Underground mining

  2. Surface mining

  3. Open-pit mining

  4. Placer mining


Correct Option: A
Explanation:

Underground mining involves extracting minerals from beneath the Earth's surface, resulting in less land degradation and habitat loss compared to surface mining methods.

What is the term used to describe the waste materials produced during the mining and processing of minerals?

  1. Tailings

  2. Overburden

  3. Spoil

  4. Gangue


Correct Option: A
Explanation:

Tailings are the waste materials left after the extraction and processing of minerals, typically consisting of finely ground rock and mineral particles.

Which mining activity is primarily responsible for the contamination of water sources with heavy metals and other pollutants?

  1. Acid mine drainage

  2. Hydraulic fracturing

  3. Mountaintop removal mining

  4. Placer mining


Correct Option: A
Explanation:

Acid mine drainage is a major environmental concern associated with mining, resulting from the exposure of sulfide minerals to air and water, leading to the formation of acidic and metal-rich runoff.

What is the term used to describe the process of restoring a mined area to its natural or a more productive state?

  1. Reclamation

  2. Rehabilitation

  3. Restoration

  4. Revegetation


Correct Option: A
Explanation:

Reclamation is the process of restoring a mined area to a more natural or productive state, involving activities such as recontouring, revegetation, and the establishment of ecosystems.

Which mining method is known for causing significant air pollution due to the release of dust and particulate matter?

  1. Surface mining

  2. Underground mining

  3. Open-pit mining

  4. Placer mining


Correct Option: A
Explanation:

Surface mining involves the removal of soil and rock to expose mineral deposits, resulting in the release of dust and particulate matter into the air.
