Introduction Iron ore. Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH)n(H 2 O)) or siderite (FeCO 3).Roughly 98% of iron ore on the global market is ...

However, mining of iron ore has copious negative impacts on the environment. As the mining method for Iron is usually open cast, it degrades natural landscapes, surface and ground water, flora and fauna, as well as the ambient air quality within the mining area and its environs.
MoreHamm et al. (2005) used a PNM to study the impact of back-filling material on water quality evolution in a flooded iron-ore mine in Lorraine. The codes used for porous media, however, are not designed for resolving flow and reactive transport in a network of fractures or mine galleries.

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 mercury into groundwater or
