It can be seen from Figure 4 that the magnetic separation effect of BOF slag is the best after 60 min of oxidation at 1050 °C. Therefore, the influence of different gas flow rates (0.5, 0.75, 1, and 1.25 L/min) on the magnetic separation effect is investigated under this temperature condition. The magnetic separation effect is shown …

Since the distribution of helpful metal minerals in the slag is complex, there is often continuous metasomatism, and weakly magnetic fayalite accounts for a large proportion of the slag; the magnetic separation effect is unsatisfactory. Magnetic separation is often used with other copper slag beneficiation methods.

Molybdenum distribution is closely related to magnetite/hematite-Fe and S. The magnetic separation results indicated that Mo and Cu were enhanced in magnetic products by 34–41 and 15–21%, respectively. Cleaner non-magnetic residues were found to decrease significantly by 37–44, 58–60, and 11–19% for Cu, As, and Cr, respectively.
