Overview The separation principle of alluvial gold is to use gravity separation to recover the most of gold and its associated heavy minerals from the raw ore first, and then use gravity separation, flotation, amalgamation, magnetic separation, electric separation and other combined actions to separate gold and heavy minerals from each other to achieve the purpose of comprehensive recovery. Alluvial Gold Washing Plant Without Sticky Clay Ore: Alluvial gold without sticky clay Capacity: Customized Equipment Used: Trommel screen + jig machine + sluice box + shaking table + gold amalgamator + gold smelting machine. Processing: 1. The raw ore feed into the trommel screen for washing a few little clays, and can separate the gravel or stone which do not contain the gold inside, which can transfer away by the belt conveyor. 2. The jig machine for catching the big particle around 2-20mm bigger gold particles or nuggets, and a sluice box capture the gold particle or nuggets again in case they flow away from the tailings. Please note the sluice box can be designed with different lengths and widths like 2m,4m,6m length,1m width or 0.5m width, etc., 3. The concentrates under the jig machine go to the shaking table again for a more good separation effect. Because the concentrates still have a little sand. Use the shaking table can separate the sand from the gold in very good effect.
This washing plant is very suitable for recovering alluvial gold ore that doesn't contain sticky clay. If the raw ore contains much sticky clay, we will recommend a trommel scrubber instead of a trommel screen. The capacity for this washing plant can be customized as per request such as 10tph,50tph, 100tph, etc., Placer Gold Processing With Sticky Clay Ore: Placer gold with sticky clay Capacity: Customized Equipment Used: Trommel scrubber + vibrating feeder + centrifugal concentrator + slurry pump + sluice box + shaking table
Processing: 1. Loader or Excavator feed raw ore into the hopper; 2. Vibrating feeder 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. Under screen 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 placer gold 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.
