- I experiment with dry shaking gold out of LA beach sand using a wet shaker table. Yes, it works! and I found some gold. Take a look, tell me what you think and make suggestions.

I've been wondering when this test would show up :) I see you have been busy refining and making new tables - looks great! Agitation, vibration, mass and gravity become very complex for a trey to recover heavies. It's understandable to see why mercury is still the cheapest and fastest choice for mirco fine gold, even today.
An oscillator can be designed to create various types of vibrations depending on its mechanism and settings. In the case of mineral processing equipment such as the blue bowl concentrator that we employ, the oscillator is used to impart controlled vibrations to the concentrator bowl. These vibrations help in the separation and concentration of heavier materials like gold from lighter materials such as sands and gravels. In fact, when an oscillator generates vibration, the position and frequency of the vibration can create geometric patterns or shapes, especially when applied to certain materials or mediums. This phenomenon is known as "Cymatics."
Cymatics is the study of visible sound and vibration patterns. When a surface or medium is vibrated at specific frequencies, the material responds by forming patterns that are characteristic of that frequency. These patterns can range from simple lines and curves to intricate geometric shapes depending on the vibration frequency and the properties of the material.
In theory, on a perfectly level table, gold and other heavy particles can settle in predictable patterns due to their specific gravity and the dynamics of how they respond to vibrations or movements. This predictability is a key principle in mineral processing and prospecting.
I recommend classifying the material, so you know the range you are working with. The "Falcon Gold Tracker MD20" should be able to detect where the gold has settled within the generated pattern much more quickly than your microscope. Once you know where the gold is, just vacuum it up.

The idea of cutting grooves or channels into a shaker table or concentrator surface to direct gold into specific zones is an intriguing concept in theory, especially in mineral processing and prospecting scenarios. Here’s how this approach might theoretically work:
Pattern Recognition: As I mentioned, once you understand the predictable pattern where gold tends to accumulate on a leveled table due to its specific gravity, you can identify these zones or lines.
Groove Placement: By strategically cutting grooves or channels into the table surface at these identified zones, you create pathways or channels where the heavier gold particles can naturally gravitate towards during the shaking or vibrating process.
Overburden Removal: The grooves would ideally direct the gold into these channels while allowing lighter materials (overburden) to remain outside these channels or be pushed towards the table edges. This separation makes it easier to vacuum or otherwise remove the lighter materials first, reducing the overall processing time and improving efficiency.
Collection Efficiency: Once the overburden is removed, you can focus on collecting the concentrated gold from the grooves or channels where it has accumulated. This targeted approach minimizes the handling of excess material and maximizes the recovery of valuable minerals.
In practice, the effectiveness of this method would depend on several factors:
- Accuracy of Pattern Recognition: How well you can predict and replicate the gold distribution patterns on the table.
- Precision of Groove Placement: Ensuring that the grooves are positioned correctly to intercept the gold-bearing zones without disrupting the overall flow of material on the table.
- Operational Adjustments: Fine-tuning the shaking or vibrating parameters to optimize the collection of gold into the grooves.
While this approach sounds promising theoretically, it would likely require experimentation and adjustment to achieve optimal results in real-world applications. Engineers and prospectors continually innovate and refine techniques like these to enhance mineral recovery processes in mining and mineral processing operations.
It's good to see you innovating as you are!
What is the MD20?
@@jessegallardo9156 The Falcon Gold Tracker MD20 is a specialized tool that enhances the efficiency of gold prospecting, particularly in finding fine gold particles that are often overlooked by less sensitive metal detectors. The Falcon Gold Tracker MD20 is capable of detecting extremely small particles of gold and other metals. It is designed to find pieces as small as 1/10th of a grain.
@@jessegallardo9156 Falcon MD-20 is a small, hand-held metal detector of extreme sensitivity. Last I looked, they cost about $300. Every serious prospector should have one.
Yes they ship a 50 mesh piece in test card @Jatslo
Your science based approach to extracting and refining is amazing. I'm in SoCal as well and have always wondered how to get any real values from beach sand. Thank you for your efforts and education.
Yeah, it's there in small quantities, sometimes. The best time seems to be after a winter storm. Look for the black sand and don't expect much. Lot's of work. Thanks for the comment!
On the tall riffle dry wash sluice mabey try bolting a vibration motor on it setting sluice at differing angles?
I've tried a vibrator and it may work, but it's hard to control.
Thanks for the video!!!
Mesmerizing to watch the blacks immediately forming it's river along the top. Take that magnet and put it in a plastic container, then pick up the magnetite and you only have to reach in and remove the magnet to drop the magnetite, which leaves you a perfectly clean magnet. I use a neodymium magnet on a string, then drill a hole thru the lid of a plastic peanut butter jar, then dump the magnet in, with the string hanging out of the hole - works great.
Maybe try the San Gabriel River maybe it's closer to you thanks
Very innovative. Thanks for the info.
I've been developing a dry sluice for a couple of years. I now have a riffle and motion that works really well, even for flour gold. The last test I did was to see if it would recover gems from mixed gravel, sand, and silt. I used 1/4" alumina spheres as the test objects, and the sluice recovered 100% of them, with the bulk in the upper 30% of the sluice. From what I've learned, both the motion, and riffle shape are important. I enjoy your videos, and respect the effort you've put into your designs.
Hi Jim, I'm interested in your design. Any further information would be appreciated. -- Dave
@@orophilia Dave, I'm still developing other tools using this particular motion. I only give out info on my designs by selling plans to build them. I don't do moneyed videos, so have no other means of keeping the shop stocked with tools and supplies. I respect your fabrication skills, and would enjoy being in touch with you, but only by email, or phone, and with the understanding my projects aren't publicized on the 'Net, except by me. I put my contact info on another of your videos last winter, with a request you contact me. 😀
May I suggest you try running, your cons. Through a grease splatter screen new of course it works great for me , then I put a strong magnet in a plastic bag and then I, take the magnet out and put that into separate container try, the table then , can't hurt to try...Good luck!!
I wonder if the grooves are even necessary. The top of the table seems to be doing a good job of separating without them.
Yeah, there are a lot of ways something like this could work.
Interesting concept
will you sell one of the table if so how much and shipping cost? I have everything else for the rest of it just the top.
Hi Gary, I'm sorry, but I don't sell anything. -- Dave
@@orophilia WHAT ABOUT PLANS THEN
Interesting! I wonder if it would work on very fine crushed ore.
Yes, I think it would. -- Dave
@@orophilia Did you manufacture that Shaker table yourself or was it purchased?
It would depend on how the ore was crushed.
@@futuregoldchannel The way it's supposed to be ultra fine after classification.
Quedó fabuloso
you're no good at this
Probably not. Thanks for the comment!
@@orophilia You get the talkers and the doers. Keep on trying, you will only get better while the talkers will still only be that, the talkers.
Dave's a really talented fabricator, and has the ability, which is rare, of thinking outside the "box".
