  • Iron Ore an overview ScienceDirect Topics

    Typical harmful minerals in iron ore include pyrite and apatite, which contain the harmful elements S and P. They are also weakly magnetic. But if their magnetic susceptibilities are smaller than for oxidized iron ores, it is still possible to partially remove them from oxidized iron ores by magnetic separation.

  • Environmental Risks of Mining

    Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.
