Mining and Water Quality

Mine drainage is formed when pyrite (an iron sulfide) is exposed and reacts with air and water to form sulfuric acid and dissolved iron. Some or all of this iron can precipitate 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, and

Effects of iron-ore mining and processing on metal

Aug 15, 2008 Aug 15, 2008 This study has demonstrated the contrasting effects of iron-ore mining and processing on metal release, speciation, and bioavailability in an impacted tropical coastal lagoon. On one hand, iron-ore mining and processing constitute potential sources of metals to the lagoon, on the other hand they also contribute to reducing metal bioavailability
