Technical. Dense medium ferrosilicon is a fine metal powder, with size distributions below 255 micron. It is used in Dense Medium Separation processes, where the powder is mixed with water to the desired medium density, and added to a DMS plant. The separation takes place in either a static (Drum) or a dynamic (cyclone) separating unit.
