There are three stages of the dense medium separation process feeding material pre-concentration, dense medium separation, and ferrous-based media recovery. Advantages of heavy media separation mining 1..Figure 11.1 Principle of dense medium separation. Since most of the liquids used in the laboratory are expensive or toxic, the dense medium used in industrial separations is a thick suspension, or pulp, of some heavy solid in water, which behaves as a heavy liquid. The process offers some advantages over other gravity processes.
