What do you guys think about using this unit to process black sands while on the beach, 5 gallons in 13 minutes and they claim no more than 3% loss, sounds pretty good and the price isnt bad when you convert to American...
I scooped out of a 5 gallon bucket with my home made set up, shoveled the black sand in the bucket and took it over to the sluice then scooped it out...
Running the material a second time doesn’t prove much to me. I would want to look at the tailings and see what it is missing.
I agree with the shovels full comment for processing on the beach. If it is truly only losing less than 3% it might be a useful step for processing concentrates.
