Moreover, centrifugal machines can be applied to small and medium feeds (e.g., after pre-concentration to recover liberated gold particles early on). Falcon and Knelson concentrators are the most popular models …
A Genuine Canadian Success Story
The Knelson™ concentrator is a centrifuge that combines enhanced gravitational force with a patented water injection process to create a fluidized concentration surface into which fine gold grains, due to their high specific gravity, can penetrate and become trapped.
Gold Gravity Knelson Centrifugal Concentrator Separator
The Gold Centrifugal Concentrator works with the same principle to Falcon or Knelson Gold Concentrator, but half or 1 in 10 price of them. Gold Centrifugal Concentrator can be used not only forplacer gold mining, but also for hard rock mining to recover the natural gold, replacing amalgamation and to recover gold from the tailings.
Modeling of Knelson Concentrator Operating Parameters …
Abstract In this study, modeling and optimization tests were conducted on enrichment of chromite ore by Knelson concentrator. For this purpose, the three-level Box–Behnken experimental design method was applied. The analysis of variance (ANOVA) was used at 95% confidence interval to test the significance of independent variables …
