High GForce Gravity Concentrators. The higher the Gforce, the smaller the minerals you can recover with a given technology. All of the Falcon Gravity Concentrators are high GForce devices that achieve forces from 100600Gs. When these forces are applied to a mineral feed, particles as fine as 3 microns in size can be selectively recovered.

Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.

Gravity Spiral Concentrator Working Principle. The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a buildup within that circuit and the eventual escape of some of that gold into the tanks and thereon into the final tails.
