In the past, this low-grade iron ore was crushed and classified into coarse and fine fractions, with the coarse fraction reductively roasted and the fine fraction processed in a gravity-high-intensity magnetic separation-flotation flowsheet. This flowsheet produces a relatively low-grade concentrate assaying around 63% Fe at a low recovery.
