Sustainable handling of iron ore tailings is of prime concern to all stakeholders who are into iron ore mining. This study seeks to add value to the tailings by utilising them as a replacement for aggregates in concrete. A concrete mix of grade 40 MPa was prepared in the laboratory with water–cement ratio of 0.5. The concrete were cured for 1, 2, 3, 7, 14 and 28 days.
The first mix was a controlled mix (without washing, jigging, cycloning, using magnetic separator etc. red mud and IOT) and the remaining four mixtures Even though left over iron ore tailing contains 20-30% of contained red mud and IOT.
conventional concrete, because red mud and iron ore tailing are the waste which comes out from aluminum production plant & iron production plant. These have already caused ecological unevenness in their respective regions and appear as the main source of environmental hazards.
A recycling process of iron from red mud by magnetic separation is proposed, in which iron oxide (Fe 2 O 3) in red mud transforms to magnetite (Fe 3 O 4) by anaerobic co-roasting with pyrite (FeS 2).TG-DTA and XRD results showed that hematite was reduced to magnetite by the thermo-decomposed compounds (iron monosulfide, pyrrhotite and element sulfur) of pyrite.
