Dense media separation utilises a medium with a density in between the density of the ore and the gangue (commercially worthless) particles. When introduced to this medium, particles either float or sink, depending on their density, as relative to the medium. Separation using this method relies solely on differences in density, without relying ...

How it works. The Dense medium separation (DMS) or heavy medium separation (HMS), or Sink-Float gravimetric separation, also known within the field of the scrap treatment as Flotation, is a process used to separate materials that have different specific weight. To obtain this kind of separation, the material to be separated is immersed into a ...

The DMS improves low grade ores via the mechanical separation of waste rock. Ores are then fed into the milling machines for further processing. It all boils down to taking advantage of the difference in density between waste rock and ore, and separating it accordingly — hence “Dense Media Separation”.

Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 µm with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process involves three steps: feed preparation, dense medium separation, and ferrous-based media recovery.
