Fine Gold Mining Machine Machines Dry Washer Design

Given a choice, most miners prefer using water to wash and run material, but in some dry, remote areas thatnbsp 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. The number one rule is that the drier the soil, the better. Damp soil conditions are very much a hindrance for drywashers. Beyond that, learning the different soil types you may encounter in the desert and how to deal with them can increase your gold recovery.

  • Recovering Fine Gold With A Drywasher Gold Prospecting

    Clay is generally known as a great gold robber, making clay-bound gravels the biggest difficulty to overcome. In most of the placers directly derived from weathering lode deposits, the placers are in ravines, gullies and hillsides with sometimes very little gravels and mostly decomposed fragment of rock and fine silt from the decomposing host rock. Host rock containing a lot of feldspars are most problematic. As feldspar breaks down, it creates some difficult clays and silts that bind fine gold to small rocks and sand with the clay and silt particles forming larger clods.

    Loamy or sandy conditions are much easier to process with a drywasher than clay-bound material due to the absence of clods and clumps. But if dirt clods are giving you grief, break them down with a large hammer on a canvas tarp, or use a mortar and pestle dolly pot.

    Once you are set up to run material, process in short runs before cleaning out the riffle tray perhaps after every three 5-gallon buckets. Frequent clean ups minimize the amount of fine gold that may creep or walk down the riffle tray with the tailings. This method uses your dry washer as a form of a classifier to screen off larger material while getting rid of much of the fine silt and lighter weight material.

    Re-running tailings can aid in the recovery of lost goldmdash especially small gold dust and flakes. The second pass through is usually much quicker than the first time because the material has already been classified. With some placers, especially flat, fine gold, rerunning material can be very lucrative. In places where gold is more coarse and angular, very little gold will like be recovered by running the tailings a second time.

  • 187 Drywashing For Gold

    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.nbsp The vibrations and flow of air replace the function of water in the normal sluice, allowing the gold nuggets to settle downward.nbsp Screened gravel passes down an inclined riffle box with cross riffles. The bottom of the box consists of a thin, light weave canvas or some other fabric through which moving air easily passes upward.

    The first design concept you need to think about is the air source. Do you want to build a bellows puffer, or a powered blower type of unit. Both work well, but the puffer type is plainly easier to build. Because of this, I recommend a Puffer type dry washer if this is the first one you are building. Remember that dry washers are such that you could always modify it in the future to switch from a Puffer type to a blower type if thats what you eventually decide you really want to do.
