Utilisation of iron ore tailings as aggregates in concrete

2021-2-12  of iron ore results in the generation of 2 tonnes of iron ore tailings (Price, 2004). It can therefore be estimated that about 632 million tonnes of iron ore tailings are generated yearly in WA. This quan-tity is so huge to the extent that if sustainable handling of these tailings is not found, it could lead to
