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.

The grade of the chromite concentrate reached 15.40% Cr 2 O 3 at a fluidization water pressure of 100 kPa and centrifugal acceleration of 150 G. At 200 G, the grade of the concentrates was below 11% Cr 2 O 3 at all levels of fluidization water pressure, resulting in low values of metallurgical recovery. The results indicate that high centrifugal accelerations, such as 200 G, caused the ...
