Photo by Rick Anderson. However, iron mining isn't "safe" either. Downstream from Minnesota 's Mesabi Iron Range, the St. Louis River is polluted with high levels of mercury and sulfates, resulting in fish consumption advisories and a 100milelong wild rice "dead zone." That's because to get to the iron,...

Acid Mine Drainage: Chemistry. The orange color is caused by ferric hydroxide ( Fe (OH) 3 ) precipitating out of the water. The precipitate forms as the acid mine drainage becomes neutralized. At low pH values, the metal ions remain soluble. When the pH rises, the iron oxidizes and precipitates out.

The current study correlates arsenic speciation in acid mine drainage and mininginfluenced water with the important waterchemistry properties Eh, pH, and iron(III) concentration. The results show that arsenic speciation is generally in equilibrium with iron chemistry in low pH AMD, which is often not the case in other naturalwater matrices.
