Fig 1 Effect of centrifugal force on gravity force. Separation of the ore particle by gravity is dependent on two factors namely (i) settling rate of the particles, and (ii) difference in specific gravity when compared against the medium in which they are being separated, this gives differential settling rate and has been termed the 'concentration criteria'.Settling rate of a …
Gravity Separation For Coarse Particles Sluice Box. A sluice box is a long tray that is often placed in or alongside a river to recover coarse gold or other precious metals from alluvial deposits. The tray is open at both ends, with the upstream section flared open to increase the flow of water through the device.
