· About 40 years ago I built a small puffer dry washer. At the time I read that a fabric by the name of Indian cloth. I used this at Goler Gulch and the cloth worked like magic. The fines stuck to the cloth like glue because of the electrostatic charge. I added riffles and very little gold escaped. I carefully checked the black sand by panning. Hardly contained any gold. Might be better ...

Gold Buddy Dry Washers are ideal for prospecting in dry or desert areas. Drywashing for gold is a surprisingly efficient method of prospecting without water. Recent developments in dry washing technology have made it possible for a one or two man operation to work large volumes of dry placer ground without water, and still obtain good gold recovery. Dry washing machines use an air blowing .

 · However, a larger sized dry washer, somewhere around 5+ yph, would be ideal for some desert loions. It could be set up relatively easily and some water could be used for dust control. I have permits to use heavy equipment on a mining claim I have. A small excavator could be used to feed a large scale dry washer very easily.

 · I think your title"Building the Ultimate Dry Washer, A Dry Washer that equals a dredge in recovery rates" is somewhat misleading. There's simply no way you can build drywasher that will equal the recovery rate of a dredge of the time. It all depends what area you're in, what size gold if found as well the type of ground. It may get in some areas but far less in others.

 · A number of small, handpowered machines are on the market and most work quite well within certain limits common to all dry washers used in gold mining. First, consider two identical gold particles, one in a dry washer and the other submerged in water. It will be shown that the relative weight of the dry gold particle is substantially less than its wet counterpart. This is illustrated by the ...
