Process Of Coal Mining Pollution
Pollution from Mining
Subsurface mining frequently goes below the water table so water must be constantly pumped from the mine. Acid mine drainage results from the outflow of water from metal mines, coal mines, or other areas in which the ground has been disturbed. Metal salts, such as Fe +2, are oxidized upon contact with air to more highly acidic aquo species....

Mining | National Geographic Society
· Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times. Prehistoric people first mined flint, which was ideal for tools and weapons since it breaks into shards with sharp edges....
