In the context of iron ore beneficiation, separation media are invariably made up of suspensions of water and very fine ferrosilicon (FeSi) particles containing ∼15% Si with density of roughly 6.8 g/cc. These suspensions perform as dense liquids with relative densities (RDs) up to 3.4 using either milled or atomized FeSi.
