The beneficiation of iron tailings by flotation poses more challenges than iron ore beneficiation. The challenges are mostly due to the fine particle size of the tailing, which falls below the optimal range for flotation (<10 μm). Also, the presence of slimes creates selectivity problems by coating the particles.
