Recovery of iron from hazardous tailings using fluidized

2020-2-1  Li et al. presented a technique for recycling iron ore tailings via the coal-based magnetization roasting process followed by magnetic separation (MRMS). Using a similar method, rare-earth tailings containing 13.06% Fe could be transformed to an iron ore concentrate assaying 45.00–49.00% Fe with a recovery of 65.00–77.50% [ 10 ].
