Magnet For Removing Black Sands

Recommended Posts

I'm looking to get a plunger style magnet for removing black sands from concentrates when finish panning.   I've seen a couple which are labeled 8 lb and 16 lb respectively.  Often bigger/faster/stronger means better, but not always.  Any suggestions?  Does the choice matter if the material is dry (as in bone dry) or wet (as in submersed in water)?

Bigger is not better.   When you remove the black sands, you also pick up some gold.  I use a smaller, black one (I'll try to find a picture)

First get last concentrates to one side of pan. Then pick up some black sand and drop it on the other(clean) side of the pan.  Pick it up again(you'll see fine gold left)  Shake the gold back to the first side and drop the bland sand you are still holding on the magnet back on the clean side of the pan.  Pick it up again and shake any gold back to the first side. Do this until you don't see any gold being picked up in the process. Discard that black sand.  Now pick up some new black sand and repeat the process.  Might be hard to understand but I'm cleaning the black sand in my pan.

I agree with the above BUT I have about 1" water in the pan and pick up the black sand under water it seems to wash the gold from the black sand when it is lifted by the magnet

Just my method hope it helps you get finer gold

Yes, those are excellent videos on the subject, in my non-expert opinion.  Thanks for your reply and filtering of the many pertinent YouTube videos.  I've watched the Mike Pung series twice in its entirity and the episodes 2 and 3 several times each.  What I really like about this series is that Mike tells the 'why', not just the 'how'.  Knowing why something works not only makes it easier to remember, but also leads to modifications and/or inovations in future experiences.

Yup... As your skill level increases you will be able to make certain shortcuts that will speed things up for you.

For instance you obviously won't have to classify to every mesh if your not in the very fine gold.

Gaining expertise in your panning will also speed things up dramatically.

Be sure that if your magnet is just a plain magnet, and not a gold recovery magnet, that you put it in a plactic bag or bottle or you can't get the black sand off the magnet.

      Hi there RR, All this gadget is doing is mechanically classifying material into a gold pan. Nothing you couldn't do with a manual classifier over your gold pan which you could possibly get away with. I know with my sluice boxing I made & use a bucket classifier than can process a lot of material pretty quickly to feed down the box.

      I tripped over this extensive article, available as a free download. Here is the abstract:
      The article sets out to clarify the special character of the North American gold pan and why it remains so popular – in spite of widespread dissatisfaction and many modifications and innovations. The North American pan is distinctive in being circular with a flattish floor ringed by an outwardly sloping wall. Its identity is confused by over-use of the terms 'pan' and 'panning'. The North American pan gyrates in a distinctive orbital motion driven by both hands of the panner. Although many other motions are resorted to (tapping, to-and-fro, tilting, and tick-tock), it is the orbital motion and flattish floor that together distinguish the pan from most other hand-held gravitational devices. In spite of its enduring popularity, no scientific tests have been published on the North American gold pan or for any of the innovations covered by 30 US patents awarded since 1861. It remains unclear if the North American gold pan is more efficient at recovering fine gold and flat gold than is a lotok, batea, dulang, ninja bowl, grizzly pan, mat, bucket or any other sort of hand-driven gravitational device. Some innovations are long-forgotten but merit attention. For instance, bars to keep the panners hand clear of the water, cables to hold large heavy pans, and several pans designed for panning without any water. Traditionally the North American gold pan was a combined digging and washing device, but today most models are not designed for digging and require a spade to be used.

      I have been working on this for a couple weeks.  It's a collapsible, customizable, self-contained, super light, 3D printed sluice box!  I know there are other folding sluice boxes, but none of them actually fit in a backpack, or are light enough to carry in one hand.  This solution would be EXTREMELY helpful!
      I'm on my phone trying this, so when I get to my laptop, I'll write in a bit more.
       
       
      So I'm currently in the CAD stage.  I have a guy that does 3D printing for me, and his machine is limited to 12"x12"x15" so I might have to shrink the size of the project down to fit, as I don't have access to, or can even afford, a larger 3D printer.
      I have this up on Patreon to attempt to raise some funding to start getting prototypes printed, and boost this project towards the finish line!

      I took a picture of my collection of crevice suckers for the Classifieds and figured it would make a good photo to post here for people to see a few designs old and new.
