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 …

Dense Media Separation

Dense media separation processes find wide use. Prior to the development of complex DMS systems, separating valuable product from waste byproducts was challenging. Yet, DMS changed the refining process for any compound where the refined product varies in density from the unrefined product. The Scrap recyclers also apply the same process.

XRF works best on the heavy metal fraction to produce individual commodities or groups, he says. For example, it can separate copper-bearing metals from other nonferrous metals, like zinc and stainless, in one pass. Then, in a second pass, it can separate that concentrated copper fraction into copper, brass, and printed circuit boards.
