the benefit of being easily recoverable by magnetic separation. Ferrosilicon has a higher specific density (6.8 g/cm 3) than magnetite (4.5 g/cm ) and can therefore produce a higher range of relative medium densities. However, ferrosilicon is more expensive and finds use primarily when the higher separation densities are required.
