Dense Media Separation of Diamonds - DMS Powders
Dense Media Separation is a well-known sink-float method and technology used within the coal, iron ore and diamond industries.In the process of Dense Media Separation in diamonds, a powdered ferrosilicon (which is an alloy of iron) is suspended in water to form a very defined pulp density (heavy liquid), close to the density of diamond (3.52 g/cm3).
