I haven't recovered much gold but the best recovery has been though the gold wheel. I run three sizes through it and clasification is very labor intensive, so I'll only use the wheel when sampling or running two gallons of concentrates. My three batches I run are -100, -50 and -20. Bigger than that I'll pan. I also run each batch through twice. THe first to get the black sand, and if its more than I can pan easily, I'll run through a second time to get the gold. I've used this for drywash concentrates, but not for my wet wash concentrates. So far my Gold CUbe and 10" sluice has not gotten enough concentrates to run through the wheel.
