chemicals involved in mining coal

Mining and Water Quality | U.S. Geological Survey

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. The acid runoff further dissolves heavy metals such as copper, lead, mercury into groundwater or surface water.
