Dry washers are devices that are used to separate gold from lighter material without the use of water. They do this by using a regulated air flow, which blows off lighter material and allows the gold to settle. It was actually invented by Thomas Edison in 1897, and the new tool provided miners with an invaluable way to prospect in the desert.

Afghans, especially the tribal, would use handfuls of sand as an abrasive to rub off filth. Another thing was, what you or I would consider stagnant and fetid water is a bath to them. Water is a scarce commodity in the ...

Late spring and, unfortunately, summer is the best time to drywash gold. Drywashers do not work well if the material has any moisture in it. If the moisture is not too bad, you can spread the gravel thinly across a tarp and let it dry. This will probably take some time though, a few hours to a day or more.

The big dry washer I posted pic of averages (40-50) grams per day, smaller ones between 3 and 5 grams per day, depending of course of the gold concentration and the type of material being processed .

Shaking the pan while gently winnowing allows the gold to settle in an action similar to a jig. A far better and more successful method is dry washing, also called dry blowing in Australia. The dry washer allows for the processing of gravels at a much higher rate than possible by winnowing or dry panning.
