  • Assessment of Environmental Impact of Iron Ore Mining

    Thus, Iron ore has been mined for the past three thousand years by ancient and modern mankind 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 theHowever, mining of iron ore has copious negative impacts on the environment As the mining method is usually open cast, it degrades natural(PDF) IMPACTS OF IRON ORE MINING ONElba Island was a hotspot of iron mining and smelting in Italy since Etruscan times (6th century BCE) Whereas the environmental burden of modern (base) metal mining in Tuscany is well studied, the impact of both ancient iron mining and smelting on soils in the region is poorly understood Therefore, we took soil samples from an ancient smelting site and adjacent areasThe environmental impact of ancient iron mining and
