Dry washing works best during the summer months when the weather has been dry. Due to its design, it is critically important that the material that is fed into the machine be extremely dry so that the vibration will allow it to break apart and gold to be able to separate naturally out of the mix.
See our new portable bedrock gold vacuum below. There is a sash new method dr mining out there in the mining community that is rapidly gaining hoow popularity, with good reason. It is called "Vacking;" and, as you might suppose, involves vacuuming material. As a suction dredge vacuums material from the bottom of the river, this is a type of dry-land dredging. It involves drg a small, lightweight unit to vacuum cracks and crevices of exposed bedrock, moss on exposed bedrock or boulders, or material in a dry wash in the desert.
For this "dry land dredging," however, there are no uncomfortable and expensive wetsuits to golc, no heavy prospecting equipment to carry and then set up, and no long period of learning how to operate the equipment, or learning where to find gold. Anyone who is familiar with mining knows that there is a much larger proportion of fine gold fod than large gold, in almost any area.
Each winter, as the rivers swell with winter rains and snows, much fine gold is washed down them. The fine gold, since wawh is much lighter in weight, is deposited much higher on the banks, or in the material of the river. As the high waters recede with the onset of spring and summer, much of the areas where the fine gold is deposited is left exposed up on the banks of the rivers.
The new units consist of a two-cycle gasoline engine mounted on a five gallon container, which is equipped with a suction hose and a crevice nozzle. They are very efficient at pulling the fine gold from moss, and at cleaning out crevices. Previous efforts to ho this by hand were slow and painstaking, and not very efficient. Collecting fine gold has always been one of the greatest challenges facing any miner, and some people spend years attempting to perfect their fine gold recovery.
Not only does "vacking" do an excellent job at recovering fine gold -- it is a lot hoe fun! It is so fast, simple, and easy to use, wasg it seems to take all the work out of mining.
You how to play mahjong book still out in the great outdoors, still getting healthy exercise, but all that's left when you ddry the excess work is the fun.
Wxsh we live and work very near a gold-bearing dey, if my husband can squeeze two hours of time, he can get to his favorite spot, set up, get in most of that time how to send email with images and still come home with enough gold to feel fof been mining. If he is dredging, that's not enough time to more than set up and get started before he has to quit!
These units come on their own back-pack frame, and all accessories are carried right inside the unit. It is a completely self-contained unit, how to make a document includes an extra fuel bottle, a crevice tool, a gold pan, a "sniffer bottle" to remove the gold from the pan, and even a sample vial to keep it in. With all these accessories, the unit weighs just 15 lbs. Many wives who are not interested in dredging or motorized sluicing high-banking enjoy using this type of unit because it is something they can do what to expect when y on their own.
The only problem we have seen develop is that when some of the husbands see that the gold recovery exceeds that of their dredge or motorized sluice, they want to use one also.
Then, they fod fight over the one unit, or join the gol group of "two-vack" families. Since they are such low cost units, this is easy dryy do. I recently talked to one avid vack-miner who has been using one of these units for two years. Gkld was concerned that he might possibly lose some of the fine gold out the exhaust as the unit filled, since it is so lightweight. Shortly after purchasing his unit, he fitted an elbow and extension over the exhaust, godl directed it into a container of water.
He has used it faithfully, and panned out the light powder that accumulated each time. He has never found even a speck of gold in it. A crack or crevice in exposed bedrock that runs crossways to the current of the river acts as a natural riffle, catching fine gold just as the riffles of a sluice do.
The moss that accumulates on exposed bedrock acts much as the carpet in a sluice, only better! It is amazing just how much fine gold can accumulate there. These are prime areas for vacking. Areas where people have been working with motorized sluicing equipment have also proven to be good. Even if they have worked the area down to the bedrock, they have been unable to clean the area as thoroughly as it can be cleaned with a Vack, and generally, the richest areas are right on the bedrock.
The greatest demonstration I have ever seen about how gold traps in bedrock and moss, and how much work it is to recover it using conventional methods, is contained in Dave McCracken's video, "Modern Gold Mining Techniquies. Even areas that have predominantly fine gold in the high bedrock will trap nuggets during flood storms, and if they are there, this equipment will help you get to them as nothing else will.
Since you do not work directly in the active waterway, and this equipment does not put anything into the waterway, there are no dredge permits required for the use of these units, at least in the state of California.
All in all, vacking has such a wide range of applications, in so many areas of the country, by how to dry wash for gold a wide range of people, that the gain wasb popularity is very understandable. It can only be expected to grow. If you should get the vacking bug, be sure you look for us out there, because that's where we'll be every chance we get!

For all intents, the dry washer is basically designed to be a short, waterless sluice. It separates gold from sand by pulsations of air coming up through a porous cloth medium. The vibrations and flow of air replace the function of water in the normal sluice, allowing the gold to settle downward. 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.
Dry Washing for Gold Most people think of creeks and rivers when they are looking for a place to go gold prospecting. The fact is that many rich gold bearing areas do not have the water necessary for panning, sluicing, or suction dredging. Many areas in Arizona, New Mexico, Nevada, and Southern California have limited water, yet excellent gold can still be found there.
There are two primary ways that the small-scale prospector can look for gold in these areas; metal detecting and dry washing. In this article we are going to discuss how to dry wash for gold.
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 , and the new tool provided miners with an invaluable way to prospect in the desert. Prior to the invention of dry washers, miners needed water to get the gold nuggets out of rich gravels. This was often done by physically moving tons of gold bearing material to other areas from processing, but in many remote areas this was not feasible, and very rich areas were abandoned.
With dry washers, these areas could be mined profitably, and they have been used in many arid climates ever since. The earliest models were hand operated, and used bellows to puff air across a series of riffles to catch the gold, while lighter material would go over the riffles and onto the ground.
Many dry washers used today are powered by a small blower motor, which provide a constant flow of air that moves a counter weighted fan that shakes the whole apparatus, allowing gold to separate out of the lighter materials. Most have a two box setup; the upper hopper uses a grizzly to screen out the larger rocks, and the lower box has a series of riffles to capture gold. Both hand operated and motorized types are used today and each has its own benefits and drawbacks.
Motor driven devices can process more material in a shorter amount of time, but the motor means that it will be louder to operate. Dry washers are less efficient than other methods such as a sluice box.
Water will always work better than air for separation, and when possible it is always a good idea to process material by panning or sluicing rather than dry washing. However, since this is not possible in many areas, using a dry washer will often be the best option. Dry washing works best during the summer months when the weather has been dry.
Due to its design, it is critically important that the material that is fed into the machine be extremely dry so that the vibration will allow it to break apart and gold to be able to separate naturally out of the mix. Many operators prefer to dig their material and let it lie out in the sun for a day or two before running it through the machine, allowing the material to dry out as much as possible.
The drier it is, the more efficiently the dry washer will operate. Another thing to consider is the use of a metal detector as a backup search tool.
Using a metal detector to scan the waste piles will help ensure that you are doing the best possible recovery. A good quality VLF metal detector that can detect small pieces of gold is highly recommended. The content of this website may not be used without written permission from Gold Rush Nuggets.
