This Machine Separated Fine Gold From Black Sand in 2 Minutes | Goldbay

Five and a half minutes of careful hand panning still left black sand mixed through my concentrate and when I checked the material I had washed away, there was a surprising amount of fine gold in it.

So I put the same 59.49 grams of mixed mine material back together and ran it through the Gold Drop.

The Gold Drop, invented by John Richmond of Sluice Goose Industries, is designed to separate microfine gold from black sand using controlled water flow. For this cleanup, I fed the concentrate through the funnel, reduced the flow from 0.5 to approximately 0.35 gallons per minute, and watched the gold collect in the vertical cleanout tube while the lighter material moved into the waste side.

From loading the material to opening the cleanout gate, the process took roughly two minutes.

The result was much cleaner gold than I had been able to produce by hand, without repeatedly chasing the same black sand around the pan or wondering how much fine gold had escaped with it.

This is one of the most practical uses I’ve found for the Gold Drop, especially when dealing with fine mine gold that is extremely difficult to clean without losing some of it.

I’ve been chasing gold since I was 11 years old. I’ve sold natural gold, nuggets, rare specimens and paydirt since 1999. Nowadays I'm lucky that I get to follow my dreams and mine full time. My hands-on experience spans gold prospecting, hard-rock mining, metal detecting, gold recovery, ore processing and crystallized gold specimens. I've also appeared on National Geographic’s Meltdown, demonstrating how gold recovery works in the real world.

On this channel, I follow gold from the first signal on the metal detectors to the final result - discovering pockets and veins, extracting gold-bearing quartz, testing equipment and recovery methods, crushing and processing ore, cleaning specimens and establishing what the recovered gold actually weighs and what makes a natural specimen valuable.

In Siberia, private prospectors primarily mine this fine gold. A method for quickly purifying this gold in the field was discovered by chance. All prospectors carry Rolton instant noodles. The containers with these noodles have a lid made of very slippery white plastic. All you need is the lid and a thin tube (like a pen tube). This white plastic has an interesting property: dry fine gold adheres to it, but the black sand does not. Apparently, this is due to the strong electrostatic properties of the plastic. Simply gently blow through the tube onto the mixture of gold and concentrated gold on the lid, and all the concentrated gold flies away, with no gold loss at all. But if this method doesn't suit you and you don't like eating Rolton, then, of course, you can look for ways to spend more money on equipment.

Great demonstration Dave! You have added an aspect of the Goldrop that I had not considered me not being a gold miner. With your insight, you have truly demonstrated the versatility the Goldrop has to offer. From processing pay dirt with 99+% recovery rate of 100 mesh Gold as established by Dave Kopp at Yuba Industries to finish a final cleanup of the recovered Gold with ease to add to the vault in the mattress as demonstrated by Dave who doesn't sleep and has no mattress! This set up is amazingly small and compact for your purpose. For the prospector, the system is expandable with multiple siphon drums to accommodate greater quantities of water to bulk process a yard of pay dirt a day classified 1/8" giving the prospector wet wash capabilities in dry desert conditions. A very much more efficient processor for Gold recovery than a dry wash puffer box sluice. Goldrop's versatility gives the Gold miner and prospector a big advantage with such a small device as Goldrop. Thanks for sharing your knowledge!

That is Jam Up and Jelly Tight !!!!

I will forever call this "The Percolator". I love watching this thing work. I can't help but wonder how this would work on a larger scale... if it would even work, or if it would require a modular setup with several similarly sized units. Calibrating the precipitation chamber seems like it would be the biggest issue.

Cool old video. There's a five dollars or so, 5 quart plastic dog bowl by Fortiflex you can get at farm supply stores that has a raised ring in the bottom center. You put your dirty gold with sands around the outside with about a quart of water, on a flat, level surface and swirl it gently so a wave travels around the bowl. All the black sands will slowly navigate toward the center of the bowl. The tiniest specks of gold won't make it over the raised ring if you're doing it correctly. You can do the same thing in any flat bottom round bowl or tub without the ring just not as effective. They also have a 12 quart pan with the ring in the center, costs a bit more but works even better and faster. No sanding of the bottom is required.

They sell a magnet with a release handle to pick up the black sand magnetite and release over a different pan.

Use a magnet, put it all into an ultrasonic cleaner with the magnet suspended , don't forget to add few drops of Jet Dry 😂

The best way is just dry the gold so dry where you can blow the sands away. It will separate, you can literally magnetize it first and get all the most of the black sands that are magnetized, but the little bit that's left over you can put down on the ground and blow the sands away perfectly away from the gold. It's easy and fast.

A trick I use to separate gold from black sand is to slowly drop the sand and gold mixture in front of a fan and by the time it hits the ground (gold pan) only gold is in the pan and the black sands are blown beyond the pan where I lay a long strip of black paper so I can see if gold is landing on the paper and usually all the gold lands in the pan…

I imagined one of these 20 years ago. Cool beens

@chrisdaniel1339 1 month ago

Use a rare earth neodymium magnet in a plastic bag to remove the magnetite which is magnetic, then there is less black sand to deal with.

@jeremystanton382 6 years ago

Wish I could afford one. The gold here is so small. I'm finding it, but it is a pain to pan. Was thinking about a blue bowl🤷‍♂️.

@richardduncan9740 1 month ago

Not exaggerating I could pan this out, BUT I would do it 1/4 teaspoon at a time with a rare earth magnet close at hand, and it would take almost an hour.
