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

During strip mining of metalcontaining ore deposits and of bituminous coal, pyrite is exposed to oxygen and moisture and becomes the source of an acidic, ironrich leachate known as acid mine drainage (AMD) (Fig. ). Acid mine drainage can have a pH of less than 2, and at that pH metal solubility is greatly increased.
had a greater impact than any other discovery until dynamite was invented by Alfred Nobel in 1867. Mining technology,like that of all industry,languished during the Dark Ages. Notably,a political development in 1185 improved the standing of mining and the status of miners,when the bishop of Trent granted a charter to miners in his domain.
