  How it works | protec

  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 ...
