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% .
1998-3-15 1.. Theoretical limitations of the sponge iron reactor (SIR)The iron/iron oxide/hydrogen process is operated in two conditions. In the first step iron oxide is reduced by the gas produced in a gasifier (biomass gas) while this gas is oxidised to a lean gas with low CO and H 2 content. In the second step the reduced iron oxide is oxidised by water vapour whereby the water vapour is reduced to
