A drywasher is a common desert mining tool for gold mining.. A drywasher is like a highbanker, [clarification needed] since it uses a motor and a form of sluice, but it has no need for water.It drywasher operates by the use of air. By forcing air to flow up through the material as it moves down the sluice, the heavier materials, like gold, will stay at the bottom and get trapped by the riffles ...
Dry Washing Gold. Perhaps the most widely used dry recovery technique is dry washing gold, using a dry washer. The dry washer is basically a short, waterless sluice. It separates gold from sand by pulsations of air through a porous medium. Screened gravel passes down an inclined riffle box with cross riffles.

Using a gold wash plant, exposed gold-bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant.The stockpiled gold-bearing gravel is then fed into the wash plant by a front-end loader or large backhoe. This practice promotes equipment efficiency by allowing the bulldozer to continue mining while the loader or backhoe feeds the wash plant at a steady rate.
Most traditional methods for recovering gold from gravels require an ample supply of water. However, an old prospector's adage has it that gold is where you find it. In the southwest, the "where" is all too frequently situated miles from even a trickle of water.Dry-washing of gold-bearing soil or gravel provides an effective solution to this dilemma.
It is critical that the gravels are fully dry because in even slightly damp materials, the clay will clump with the gold preventing good recovery. As a result, any gravel must be thoroughly dry before treatment. During dry times of the year the gravels may be naturally without water, but after stormy periods drying may be required.
Using a dry washer is a great way to find gold in many areas in the southwest. Limited water makes gold prospecting difficult in many regions, making common mining methods like panning, sluicing, and dredging impossible. They are a great way to find gold in …
Dry washing requires that the sand and gravels being dry washed are powder dry. If necessary, shovel the material onto a tarp to dry in the sun, then poured into the grizzly. Dry washing is very efficient, but not quite as efficient as dredging. But, when water is scarce or non-existent, dry washing is the method of choice. Good Luck.
I do wash and fold because I have to use the laundry room in the basement of my condo. At $1.75 to wash and $1.75 to dry a load and the fact that if you don't get the laundry out the second it is done, someone dumps your clean laundry (either wet or dry) on a less than clean surface, it's more than worth it to me.

The Keene Hand Crank Mini Dry Washer is one of the lightest, most compact, and effective drywashers that you can purchase today. The oversized hopper allows you to control the flow of material to your desired setting, and the crank turns easily.
Recent developments in dry washing equipment have made it possible for a one or two-man operation to work larger volumes of dry placer ground without water, and obtain good results in gold recovery. Dry processing recovery systems generally use air flows to do the same job that water does in …
"If the ground has not been worked over many times and the bottom of the wash not carefully searched, a painstaking cleaning of crevices and potholes may yield lucrative results." Lucrative is an ill-defined word here. GPAA member Judy Miller has searched for gold in these stream beds using both dry- and wet-wash methods.

The riffles are installed the opposite direction in a dry washer as compared to a water box. Even though I live in Arizona I am not a fan of dry washers because the material needs to be very, very dry, they are way to dusty for me and in my opinion the fine gold loss is higher than a water box.
Dry-Washing for gold goes back to the earliest days of gold discovery, where water was not available to separate the valuable minerals from waste sand and rock. The early miners devised crude methods of utilizing the flow of air and vibration to concentrate and separate valuable materials like gold and gemstones from sand and gravel.

A dry washer separates gold from sand by pulsations of air coming up through a porous cloth medium. It is the gold prospecting equipment of choice in desert areas. The vibrations and flow of air replace the function of water in the normal sluice, allowing the gold nuggets to settle downward.
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 ...
Not a good practice. Note: Make sure the wash doesn't pool too much. As a wash dries it shrinks a little. Too much wash in a small area could lead to unsightly stain-like dark edges. As with painting, apply washes in layers if you want more pigment applied to your model. Ultimately, liberally apply wash, but maintain control.
