Low dense media process: a new process for low-density ...
The low-density media separation process. The LDMS process is defined as a DMS process where the dense media solid, used to make up the suspensoid, has a density lower than 1.00 g/ml. This way, the suspensoid will have a density lower than 1.00 g/ml. The following equation is valid for calculating the media density, δm: (1) δ m =γδ s + (1 ...

Density Separation - an overview | ScienceDirect Topics
Magnetic density separation (MDS) is a density-based sorting process realized utilizing a "magnetic fluid" constituted by a liquid (i.e., water) and magnetic particles (i.e., iron oxide particles of about 10–20 nm) suspended in the liquid (Bakker et al., 2009).Through a special magnetic field (Rem et al., 2013) an artificial gravity is produced, as a magnetic force.
