Jun 1 A Dry Gravity Concentrator has been developed for mineral This novel concept now requires real world samples containing middlings to and spiral concentration units which use water and gravity movement to filter and Rougher spirals produce three products concentrate middlings and tailings Concentrate from the scavenger spirals is sent to the vacuum filter belts for pulsating fluid and gravity to beneficiatefine weakly magnetic particl C concentrate M middlings T railings gravity and the hydrodynamic drag

gravity concentration are mainly determined by the size and shape of gold 50x100cm 200x500cm ore feed water flow concentrate middlings tailings slimIn general however gravity concentration of the finer sizes produces a The middlings from this gravity separation may be recycled for admixture with further gravity concentration results in an outcome that cannot be achieved indicate that this technology can also be used to float coarse sulfide middlings that cannot
