Advances in Gravity Gold Technology - ScienceDirect
The economic benefits of gravity recovery are application dependent, as shown in Table 19.2. For more than 95% of all applications, gravity recovery targets GRG to supplement cyanidation or flotation, thereby increasing overall gold recovery by 1–10% and reducing some of the costs associated with carbon stripping and regeneration.

Gold Recovery with Centrifugal Gravity Concentrator
Here is how a gravity gold concentrator (centrifuge) works as a separator: Make sure the concentrator has been correctly assembled and that all bolts have been tightened. If required, attach a funnel to the material feed inlet. If necessary, connect a hose to the tailings outlet. Place the concentrator on a raised structure such as blocks.
