Choosing The Correct Gravity Separation Machine

High G-Force Gravity Concentrators. The higher the G-force, the smaller the minerals you can recover with a given technology. All of the Falcon Gravity Concentrators are high G-Force devices that achieve forces from 100-600Gs. When these forces are applied to a mineral feed, particles as fine as 3 microns in size can be selectively recovered.
