Reverse Flotation Iron Ore Tailing Environmental Impact

  1. Reprocessing of Sangan iron ore tailings by flotation

    Hence the iron ore minerals with lower magnetic susceptibility or interlocked with gangue minerals have no opportunity for upgradation and proceed to the tailing dam Flotation is a powerful technique for upgradation of these materials and it is the focus of this research A sample of 43 09% Fe and 12 1% FeO was taken from the tailings of second step of magnetic separation The ore minerals of the
