Understanding the Gold Centrifuge by Comparing it with a Sluice …
Gravity concentration was achieved with pinched sluices and 76cm Knelson bowls, with a significant increase in fine gold recovery. Again, the first material fills the rings completely. At this point, any similarity in the two centrifugal type concentrators begins to separate as the unit greatly enhances and improves the centrifugal factors.Web

Advances in Centrifugal Gravity Concentration
One final note about centrifugal concentrators for gold recovery is that they provide very low concentrate mass yields, often less than 0.05%, and consequently very large mass concentration ratios, exceeding 5000:1, for the largest units. Hence, these units are ideally suited for gold as it occurs at less than 20 g/t in most ore bodies.Web
