Fine Gold Recovery Devices for Cheap?

Recommended Posts

I watched some of those guys using a paint brush

to move gold particles in slow moving water in a

metal trough, like a sluice, without the riffles,

for a simple description. It had a small header

box, with ball valve to control the speed of the

water. Worked really good.

I learned one of the secrets of the thing was the

black finish was none other than a metal primer spray,

which provided a slight slowing action of the descending

gold and other particles. There could be primer that

is more coarse than others, but I wouldn't know which

might be best for the project.

**(If the sluice is aluminum, as most are, I would be sure

to use primer spray paint FOR aluminum. Don't know about

sluices, but it does make a difference with boat motors.)

Boat motor primer is usually a yellow color, so maybe the guys used what they had, being plain old black primer.

Regulation of water control amount and speed, angle of the box itself, is key, obviously.

Once you get a few of those few items, and with experimenting,

you may have a relatively inexpensive method of fine gold

recovery. Oh yes, don't forget to have a capture bucket at

the end of your setup, in case you think you may have

lost some of your fines.

Hope this helps...

I've heard of people putting sand in paint and then painting the bottom of a bare sluice box.   Like a non-slip step.

I am using a product that is intended to be used as shelve liner. It's a very thin rubber mat called Easy Liner and sold by Walmart. It's the same matting used in the Black Magic machine posted on page 1. I used 3M 77 spray adhesive to secure the mat to the aluminum. The mat has a slight texture to it that gold sticks to.

How would this wonder mat do in a gold pan or maybe 1/4 of the pan surface, or up on the pans slope, might be worth experimenting with it?

  Ps, I got the cheap ABS Black Miller Table off Ebay for $ 50 shipped and altho it included a few extras like Teflon tape and a cheap ball valve, it is NOT as easy to get up and running as the YouTube videos implied. Altho,I have to admit I did NOT like the idea of using a 110 volt pump to power the setup, scares me to think of electric shock hazards? So, I found an Atwood 500 gph 12 volt bilge pump I had and am attempting to mate that to the ball valve.Had to go to Ace hardware and get 2 garden hose adapters with 1/2 and 5/8 inch barbs on them plus garden hose screw on fittings on the other ends, 1 female and 1 male. And finding a suitable tub to fit wasn't easy either.I finally acquired a 10 gallon tote from Ace hardware that is gonna have to work with the sides squeezed together a little bit and a small tub inside to catch my tailings. The cross bar that was provided for the table to set on was just that and no brackets to hold the table in place so I drilled and bolted on 2 right angle metal brackets today. I would say this Miller table is ok for lite duty home use but field use is doubtful unless you baby it.The ABS plastic is almost paper thin, not the rugged thick ABS black plastic like is used on Bazooka sluices, like it needs to be. 

  I hope to have all the bits and pieces together tomorrow for a test run.I also just found my California Sluice Box company concentrator sluice so will try that too. I can fit a garden hose up to that one and it is rugged enough for field use. It uses those drop riffles in a narrow 3 inch wide x 2 foot long sluice to catch the fines and mounts on a 5 gallon bucket.

  Now,if I could just find my digital camera? It disappeared after my last mining trip.Small cameras are nice but they can disappear easily. KInda hard to wrap them in bright red duct tape like my shovels so they stand out better?

How do I classify my fines for the Blue Bowl  without having to spend a lot of money on various mesh screens? What mesh is window screen? How about them colander things we use in the kitchen with the cone shape fine wire mesh? I watched several YouTube Blue Bowl videos but they don't really explain how the Blue Bowl works or the theory behind it? I never saw the gold results afterwards either?

   I actually do have one of these bowl things but never felt very confident on using it, so it sits on a shelf. Guess I need to get brave and try it out before winter gets here. I printed out some directions for using it tonite, will need to look it over and see what parts I have  or need to buy yet.

Thanks for all the responses.



TVANWHO - Window screen is generally measured at about an 18x14 wire mesh - found that info and a lot more on wire screens and wire cloth here: http://www.bwire.com


As far as spending a lot of money on wire screens and attaching them to your bowl - I do not believe that as a DIY project, this would be hard or expensive to execute.  Simply go to the local hardware store - ask what they have laying around - and generally they will have something fine enough for you to use.


Wire mesh - unless you are buying a huge quantity, a rare metal, or something that is so fine that it becomes hard to find and acquire will and should not be very pricey.  Simply cut the mesh to the shape you need with aviation shears and fasten it to your bowl or funneling device!

You guys have any thoughts on these Underflow Mini Sluices 


There is a ton of youtube videos.


Here is the web site of the builder, does look pretty easy to build one DIY.

Just my personal opinion but when it comes to sluices just give me a good old aluminum box with carpet and remove able steel riffles. Good old Keene A-52 is still the standard as far as I am concerned.

  • I think most people don't know how to clean the green carpet in the a52. that green carpet catches fine gold, but you have to wire brush the carpet in a tub of water. if you have never done that with your carpet, try it.

      So, after playing around with a few ideas, I figure it's time to go ahead and make a larger scale sluice.  No tiny 95GPH flow, this is going to be 500GPH.  That's just over 5 times as powerful as my previous "pocket sluice".  This is basically a small Gold Cube.  Half the width, and scaled down in some areas.  This one is designed to take real gold sluice rubber matting.  I bought two types, one is generic "High-Low" matting that's 2.3mm tall.  The other is "Vortex" matting, and it's 7mm tall.
      The trays I have are designed to print with minimal supports and material, hence the honeycomb grid.  There is a little angular lip at the top of the matting area that keeps the top of the mat in place, and places the water and material flow completely onto the mat.  The little pegs at the bottom keep the mat from sliding down, and and small enough to not impede water flow in any meaningful capacity.  The underflow section at the top is actually the exact same dimensionally as the Gold Cube, so that the water flow works correctly.  Under the foot where the underflow is, is a cutout that fits into the raised pegs at the top of the bottom end, so they can stack neatly.  There is only 0.3mm of play between the parts, so that it's a nice, tight fit.
      The top tray, or "slick plate" is the same general idea, and has a 9 degree angle, just like the matting tray.  The red lid slides into the slot around the top, and creates a tight sealed box that directs the water flow.  It has only 0.3mm of clearance.  The back of it will end up having a threaded tube, 3/4" to allow a bilge pump to be hooked up to it.  What's not pictured here is an additional piece that directs water flow down to prevent excess splashing and uneven output.

      I found some good gold in clay. Sticky, greasy stuff but shows promise. So I ask you old sourdoughs, what is the best way to process this material? I have been smooshing it by hand and then panning but it's not very efficient!

      This is a 3D printed blue bowl version 1, it worked amazing for doing my last big clean up and sucked the sand away very quickly. I didn’t want to pay an arm and a leg so I built my own, leave an e-mail if you want the file. The whole project cost me less than 30 bucks or so. 
      -172 GPH Pump 
      -3/8 Tubing 
      -On/Off Valve 
      -12  #10-24x1in Screws 
      -9 #10 Washers 
      -Rectangle Tub 
      -Small Bucket 
      -Printed Parts

      Well, as far as I can tell, it's the smallest FUNCTIONAL sluice box.  This isn't a cute scale model to look like a neat paperweight.  This thing actually WORKS!  Let me know what you think!  This has taken me well over 4 months to develop past where you saw it last time.  I still have a few minor tweaks I want to do to it, but all in good time.
      As long as you can spoon feed it small enough material, this will work for you.  I guess this would be more suitable for processing concentrates, but it should still be a hefty worker!
      * Self-contained power (4x AA rechargeable batteries @ 1350mAh each)
      * 3x 120 LPH micro pumps @ 6volts each
      * Self-recycling water system
      * Can be used as a single or double tier system
      * Sluice trays are set at 8 degrees
      * Removable riffled drop-ins (currently printed in green) (upgradeable/swappable)
      * Debris catch bin for removing excess material from the basin
      * Scotchbrite scouring pad used as a particulate filter to prevent pump clogging
      * Fully disassembles and packs into itself for painless transportation
      * Watertight, isolated battery compartment won't get wet from splashes or overflow
      * Drain holes to prevent water buildup around solder connections to pumps, and in storage area
      * Spare storage area can be used for rubber mats, vials, filters, etc
      * Riffled trays (3D printed) designed for use in this system with its specific flow rate/angle
      * Quickly comes apart for cleaning of the trays or storage
      * Currently takes 687.52 grams of PLA filament @ 1.75mm  (52 hours to print on my settings)
      Things I want to improve in my next version:
      * Isolate the pumps better so they don't suck up material or silt
      * Raise the edges to allow it to process larger piles of material without spilling over the sides of the trays
      * Make a better trap to catch the waste material, rather than let it build up in the main basin
      * Design riffle drop-ins that are more easily removable
      * Possibly design different types of riffle drop-ins
      This one was just before this 2-tier version, when it was at a single level.
        Check out this point in the video, where a pretty good size nugget shows up!

      Just finished this project, figured somebody might like it around here.

      My sister ran into a fossiker when out camping who was having an issue with tiny shot while finish panning.  He was sucking the shot into his snuffer bottle when trying to collect the gold.  Any suggestions?  I have a feeling he's not the first person to be annoyed by this.
