Flowchart Explanation For Rock Gold Processing plant:
1. Loader or Excavator feed raw ore into the hopper;
2. Vibrating feeder feed primary jaw crusher; primary jaw crusher is to crush big stone to medium size.
3. Output of primary crusher sent to fine jaw crusher by belt conveyor; fine jaw crusher is to crush medium sized stone to small size.
4. Output of fine jaw crusher sent to vibrating screen by belt conveyor;
5. Oversized rock is back to fine jaw crusher for further crushing by belt conveyor;
6. Undersized materials sent to one transit ore bin by belt conveyor;
7. Fine ore in transit bin is sent to ball mill via electromagnetic vibrating feeder+belt conveyor. ball mill is to grind ore to powder size.
8. Discharge of ball mill goes to spiral classifier for roughly size separation. Coarse particles will be back to ball mill for further grinding;
9. Fine particles will be sent to the centrifugal concentrator for concentrating fine gold by a slurry pump.
10. Tailings of centrifugal concentrator go to sluice box for recovering more gold;
10. Concentrates of sluice box and centrifugal concentrator are sent to shaking table for fine concentrating gold.

The ball mill + classifier forms a closed-circuit grinding system, which can achieve more than 90% of the discharge to 200 mesh(0.074mm)

So this flowchart is very suitable for recovering fine powder gold in rocks.
