Dense Media Separation (DMS) Plants

Dense Media Separation. A heavy medium is a heavy-fluid or heavy suspension fluid with a density greater than that of water (1g/cm3). The process of separating ore particles in heavy media is called Dense Media Separation / Heavy Media Separation (DMS / HMS). The heavy medium separation method is an advanced gravity beneficiation method.

Bulk ore sorting improves profitability and sustainability

This often means that the process includes a blending strategy to ensure a stable feed grade to the plant. Maximizing the value of bulk ore sorting requires a shift in mining practices. The goal should be to exploit the natural variability in the deposit rather than blend it out. A perfect complement to in-pit crushing and conveying
