Placer Gold Processing Plant Flowsheet Design （Rotary Scrubber+Knelson Concentrator）

Flowchart Explanation For Alluvial Gold Washing Plant: 1. Loader or Excavator feed raw ore into the hopper; 2.Vibrating screen feed trommel scrubber.Trommel scrubber is to wash off clay from ore, and screen out different sized particles. 3. Overscreen materials of trommel are transported to far place by belt conveyor, this is waste sand. 4. Underscreen materials of trommel are sent to the centrifugal concentrator by a slurry pump.Centrifugal concentrator is to concentrate 0-5mm fine gold. 5. Tailings of centrifugal concentrator will be sent to sluice box for recovering more gold. 6. Concentrates of sluice box and centrifugal concentrator are sent to shaking table for fine concentration gold in order to increase the purity of gold content. This flowchart is suitable for any type of alluvial ores, especially alluvial ores with sticky clay, gold particles with 5mm below. If the gold particle size is bigger than 5mm, just add one more sluice box for recovering gold nuggets with 5mm up.
