Separation Density

The most common media for separation is a fine magnetite suspension in water, ferrosilicon suspension, or a mixture of the two, depending on the required separation density. Magnetite alone is used when a density is required in the range from 1.25 to 2.2 g/cm 3, a mixture between 2.2 and 2.9 g/ cm 3, and ferrosilicon alone for a density range ...
