The “DMS” Sink-Float Gravimetric Separation is a process of mining origin used for beneficiating minerals. In recent times this type of application has been widely used successfully for the separation and recovery of metals from scrap.

Protec’s twenty-year experience in this field allowed extending this technology also to the recovery of metals from incinerator slag and the separation of plastics.

For each separation process Protec has developed a different type of system employing for each of them the most suitable separation drum.
