The ore was crushed to −2 mm by a roll crushing mill (XPSF Φ400 × 250), and then ground to ore fines (− mm) by a ball mill (XMQ Φ240 × 90). The ore fines were recombined with different magnetite ratios for singlefactor experiments to explore the effect of the original magnetite improving the iron ore separation index.
