Jun 16, 2011 Removing iron by oxidation and filtration. In cases of iron levels higher than 0.3 ppm, sequestration is not possible, and therefore the iron must be physically removed from the water. Removing dissolved iron is a two-stage process • The first stage is oxidising the dissolved iron and transforming it from soluble form to insoluble ferric.

Water pollution due to seepage from tailings pond was studied by Variably Saturated 2-D Flow and Transport Model (VS2DT) and it was found that the pond seepage of iron from tailings pond to groundwater would be negligible even after 3 years. Therefore groundwater would not be adversely affected. Tailings pond, impacts, ground water, heavy.
