UTILIZATION OF IRON ORE TAILINGS AS REPLACEMENT

2019-4-21  India is one of the important iron ore producers and exporter in the world. However, the rapid growth in production, especially from large surface mines, have already caused ecological imbalance in their respective regions and emerge as the source of main environmental hazards. The waste/tailings that are ultra-fines or slimes, having diameter less than 150 μm, are not useful and hence are discarded. In India approximately 10 – 12 million tons of such mined ore is lost as tailings. The safe disposal or utilization of such vast mineral wealth in the form ultra-fines or slimes has remained a major unsolved and challenging task for the Indian iron ore industry. In future, the proportion of iron ore wastes generated is likely to increase due to higher demand for iron ore as a number of steel plants have been planned for future in many parts of the country. In order to reduce the adverse impact of indiscriminate mining of natural sand, iron ore tailings which is the waste products of mining industries is used as an alternative to the river sand in the manufacturing of concrete.
