Jun 15, 2012 · Most diamond mining is alluvial. Alluvial diamonds are recovered from their surrounding gravels by means of dense medium separation (DMS). DMS uses a water rich suspension of ferro-silicon to float off the quartz sand (with a density of 2.7 gcm^-3) from the diamonds (with a density of 3.45 gcm^-3) which sink to the bottom, pass through an x-ray machine & are then caught in a trap.
