[QUOTE="Silversurfer, post: 363294, member: 8367"] I really think it comes down to classification for 'fines'. If you have the available Mesh sizes I would suggest that you pre classify to at least -10 to -20, -20 to -30, -30 to -40, -40 to -50 ,and so on down to about a -150. Anything smaller than that is not really worth the time and effort of extraction....I know it all sounds a bit of a cliche about classification,but it couldn't be closer to the truth as the gold becomes finer and the possibility of it becoming disturbed while trying to settle in the capture zone of your sluice or miller table. If you go with a recirculating set-up make sure you filter the water as much as possible each cycle. Dirty water will corrupt the whole process of recovering fines,that's why most high bankers have very poor retention rates for fines, I don't care what those knobs at Gold Rat or Gold Hog tell you....they're wrong...if you need more info let me know. Good luck. [/QUOTE]
