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.
Place a receptacle under the barrel to collect the concentrate.
Make sure the water and electricity are properly connected.
Make sure the bowl inside the concentrator can spin freely

	Open the process water valve so that the pressure is within the operating range (70-120 kPa / 10-17 psi).
	Press the “run” button. The bowl will start spinning
	Press the “increase speed” button until the display shows 45 Hz
	Feed slurry into the concentrator. The particles must be smaller than 2 mm
	After about 30-60 minutes, stop feeding slurry into the concentrator.
	Reduce the process water pressure.
	Press the “decrease speed” button until the display shows 5 Hz.
	Open the rinse water valve and use the rinse hose to wash all the concentrate from the bowl.
	Collect the concentrate from the receptacle for further processing
	Close the rinse valve and open the process water valve (70-120 kPa / 10-17 psi). Then repeat Step 5 to Step 10.
