Consider this situation. I dry wash in a location that is a half mile or more from where I park my truck so I am thinking about keeping the weight carried out to a minimum. That is important when you get to be my age.
I am thinking about re feeding all of my collected cleanups as my last run of the day and just taking the one tray of concentrates home. My thinking is that doing so should super concentrate what I have much like what some people do which is to pre pan wet process concentrate to eliminate obvious waste material and reduce the volume of concentrates they take home for recovery eg. mostly black sands. I have sampled my washer tails from a couple of outings and have found no gold in them. That leads me to believe that re running cons will yield the same results...virtually no losses. One thing that got me thinking about re running dry washer concentrates to super concentration is that some times the tray bogs down when there is an excess of larger material in the tray. Stony feed is the nature of the beast where I currently dig and 1/8" and larger stones make up a fairly large portion of collected concentrates. I think re running collected concentrates will mostly save the smaller and/or denser material (heavy black sands and gold) and eliminate much of the waste. That conclusion partially from a tip from the builder of my dry washer which was that adding a shovel of fines through the hopper usually encourages the larger, less dense stones to move on out and make the washer active again....and it does.
So, the question again; "Do any of you do this"?
