GRAVITY CONCENTRATION OF GOLD FROM CYCLONE FEED IN GRINDING
Cyclone underflow contains the greatest opportunity for gravity concentration since it is the highest grade. (Please refer to flowsheets included.) Recovery across the enhanced gravity device will be improved by the absence of slime. Free gold that escapes from grinding circuits via cyclone overflow will all be recovered by

Gold lost in ball mill
If the cyclone underflow gold grade was higher than the cyclone overflow grade then you have free gold and you should look at putting a centrifugal concentrator in the grinding circuit. For low tonnage operations you can feed 100% of the ball mill discharge to the concentrator (this requires an extra pump, but is worth the effort).

Hydrocyclone Working Principle
The entrance to the cyclone was designed this way to allow the incoming feed to help generate and not interfere with the spiral path that the ore must take inside the cyclone. The centrifugal force ( the central Hydrocyclone Working Principle ) that is generated by this spin, forces the “bigger particles outwards towards the wall of the cyclone.
