Simulation of particle-laden flow in a Humphrey spiral ...

Abstract This paper demonstrates that our extended smoothed particle hydrodynamics (SPH) model can successfully simulate multiphase flow in a Humphrey spiral concentrator (HSC) with two phases: powder and water. The powder phase in the model was assumed to be a continuum, as the spacing between particles in this state is much smaller than the typical length scale of flow.

Gold Centrifugal Concentrator - Mineral Processing

The centrifugal concentrator rotates at a high speed, generating a high "G" force, which can separate small gravity recovery gold (less than 50 microns), which was of previously unrecoverable with traditional mineral jigs, spiral separator, and gravity tables. In recent years, the application of centrifugal force has proved to be an effective technology for recovering fine and heavy minerals.
