Development of the Falcon Gravity Concentration Equipment

A 100 mm (4") lab unit collects about 100 grams of concentrate, enough for screen and assay. The recommended 5 kg. batch of feed gives a 50:1 mass concentration, high enough to define gravity recoverable gold in low grade samples. This large original sample became a useful tool for geologic assessment and testwork.

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.
