DRY Shaking Air Table to Recovery Gold

Air tables use a shaking motion similar to that of shaking tables, but instead of water, air is used to separate heavy minerals. The table deck is covered with a porous material and air is blown up through the deck from a chamber underneath. The chamber equalizes the pressure from the compressor and thus ensures an even flow of air over the entire deck surface. Generally, air tables consist of ...

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.
