(PDF) Recovery of Gold from a Free-Milling Ore by Centrifugal Gravity
4. CONCLUSION The mineralogical analysis of the Mastra gold ore has shown that gold occurs as associated with quartz and sulphide minerals, and as particles of 1-300 μm in size. The gold particles, having a size of ≥150 μm, were estimated to be 50% of the gold present in the ore, indicating its potential for gravity recovery.

Centrifugal Gravity Concentrators
These units consist of a riffled cone or bowl that spins at high speed to create forces in excess of 60 times that of gravity. Slurry is introduced into the cone; the centrifugal force produced by rotation drives the solids toward the walls of the cone. The slurry migrates up along the wall where heavier particles are captured within the riffles.
