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. Water quality is contaminated due to surface runoff and leachate that are generated from large volume overburden and
