A strong candidate for gravity separation is the recovery and concentration of hematite (ρ 2 = 5000 kg/m 3) from silicates (ρ 1 = 2650 kg/m 3), which in a medium of water (ρ L = 1000 kg/m 3) gives R = 2.4. Hence for most examples of gravity concentration the density driving force for separation is a buoyant density ratio smaller than 2.4.
