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 wet recovery

2013-2-19 Dryblowing is a sure way to recover gold and am convinced the bellows type retains gold down to mustard if it is set up correctly and the dirt is dry, I mean dry, not slightly damp. It is a sure way of returning everyday with a little gold as opposed to detecting. Keeps you fit and well blended in with surroundings being covered in red dust.

2016-11-4 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.

2017-12-29 Recovering Fine Gold with a Drywasher. Given a choice, most miners prefer using water to wash and run material, but in some dry, remote areas that is just not feasible. If you focus on the natural conditions that exist in desert regions and work with them, you can maximize fine gold recovery.

Even today, some dry washers have trouble recovering gold after the top layer of dry sand has been removed, due to the moist sand and gravel below the surface. New technological improvements allow modern units such as the 151 drywasher model made by Keene to help dry out this material and increase gold recovery to very high levels.

2019-2-6 velocity. This method of dry recovery can be extremely effective when the proper balance of air separation, vibration and static electricity are employed. The concept of air separation and metered vibration is vital for dry concentration of gold. Keene Engineering has employed an adjustable oscillation system that creates a balance of vibration and air

2018-4-2 GOLD BUDDY drywashers are an excellent tool to recover gold from dry material. Because the nature of the material can vary widely from fine dust to gravel and the gold being recovered can vary in size from chunks to very small pieces the size of face powder a drywasher can be configured to maximize the recovery rate in any circumstance.

2021-5-4 A drywasher recovers gold because of the following characteristics. (1) The recovery box is shaking, allowing more dense material to sink. (2) The material in the recovery box is being fluidized by a constant cushion of air, which also allows the more dense material to sink quicker. When the gold reaches the cloth it is trapped under the riffles.

2014-6-22 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.
