Gold nugget recovered by simple panning
After washing the concentrates as created by neighbor, all the details of such concentrates have been analyzed. The procedure have been tested and devised which would be the best to collect simply all of the gold.
The concentrate was such that it could contain even 3 grams big gold nuggets, which we did not find today. It contains a lot of fine gold due to the accumulation of black sands found in spaghetti carpets or miners' moss, and it contains a lot of smaller nuggets of the size of about 30-60 mesh.
The solution for the improvement of this operation is very simple. First would be to implement screening and separation of larger particles. Then to place few well known Hungarian riffles to capture those largest nuggets, to exclude the mercury out of the story, as mercury is a pollutant and disease generator, and to use sophisticated sluice for gold recovery. Instead of concentrate of 100 kilograms, one may get just 5 kilograms and then super-concentrate it and pan it to recover the gold.
