water pollution due to iron mining

Mining and Water Pollution — Safe Drinking Water Foundation

Jan 23, 2017· Types of Water Pollution from Mining. There are four main types of mining impacts on water quality. 1. Acid Mine Drainage Acid Rock Drainage (ARD) is a natural process whereby sulphuric acid is produced when sulphides in rocks are exposed to air and water. Acid Mine Drainage (AMD) is essentially the same process, greatly magnified.

Pollution From Mining TheWorldCounts

The water pollution is caused by acid that drains from the “Iron Mountain” mine, known as acid drainage. Acid drainage is serious stuff. With a pH value of 0, the groundwater near the “Iron Mountain” has been found to be 10,000 times more acidic than battery acid (this is VERY acidic).

Mining and Water Quality USGS.gov

Mine drainage is metal-rich water formed from a chemical reaction between water and rocks containing sulfur-bearing minerals. The resulting chemicals in the water are sulfuric acid and dissolved iron. Some or all of this iron can come out as solids to form the red, orange, or yellow sediments in the bottom of streams containing mine drainage.
