Sep 01, 2016 Millions of tons of iron ore tailings (IOT) a by-product of iron ore processing, are disposed of every year in landfills, quarries, rivers, oceans among others thereby posing environmental problems. The major aim of this study is to evaluate IOT as replacement for river sand in concrete and compare with the result of conventional concrete. tailings from the iron sand mining. The total volume of sediments derived from the iron sand mining in the plain is estimated as 7.7 x 107 m3. This figure indicates that 30 to 40% of the earth volume through the iron sand mining in the upper reaches of the river Takahashi was supplied to the western part of Okayama plain. 4.
