Looking for a gold recovery product that can process tons of concentrates into mere ounces? The Gold Cube can retrieve your gold from the material you've gathered from rivers, beaches, black sand, etc. With a 12-volt battery (not included) you're ready to clean up your concentrates QUICKLY!
Why would you want a 4 Stack versus the 3 Stack? Both set-ups do exactly the same great job of recovering fine gold. Having a four stack is like having a 48 inch sluice instead of a 36 inch sluice. That extra foot of sluice provides a little more assurance you'll catch the gold. A fourth stack on your Gold Cube kinda does the same thing. It's definitely not mandatory, but can help make sure you capture every little bit of gold in your material.
No matter which size you choose, the Gold Cube is a small enough to fit into the trunk of your car and consists of stacking trays made of indestructable plastic LDPE (low density polyethylene) that's as thick as a cutting board. Includes the manufacturer's 30-day money back guarantee; pump carries a 1 year warranty.
4-Stack Deluxe Gold Cube includes:
• One Slick Plate
• Three Separator Trays (each tray approx. 16 x 16 x 8 inches)
• Stand (improved September 2022 - no welds to break!)
• Pump - The wires on the pump are about 24 inches; alligator clips are included so you can easily clip on the wires
• Hose Adapters
If you've got lots of paydirt to process, the Gold Cube offers you convenience and accuracy, hence the company slogan "Cube It or Lose It." This new technology is far more efficient than panning out your gold by hand. And with the Gold Cube, the vortex it creates acts like quicksand and buries your gold so you don't lose it like is possible with a sluice.
But how does it work exactly? In mining, the low pressure zone behind a riffle— in a sluice or dredge— is called an eddy. The eddy rolls horizontally and the vortex churns vertically like a tornado. "What happens in the vortex is the tornado effect that stirs up the dirt. It's like when you've got a pan with gold in it and you shake it... the gold sinks to the bottom," says inventor Mike Pung. "The material is churning and is really soft in the water, so the gold sinks to the bottom and it's going to stay there until something heavier wants to displace it. And since I've got gold sinking to the bottom of a vortex pocket that already full, gold will sink to the bottom and something equal to that size is kicked out. So the Gold Cube and the vortex technology basically operates on a replacement system."
In other words, gold, because it is about 19.3 times heavier than water, simply keeps pushing out the small gravels and lighter sands as it flows through the Gold Cube and gets trapped. Once a pocket is completely full of gold, heavier material and new gold entering the Gold Cube are forced to find another pocket.
ACTUAL CUSTOMER COMMENT: "I just wanted to say thank you for the best system I have purchased for gold mining. And believe me I have bought more than 5 different systems. I primarily mine on the Pacific Coast dealing with heavy black sand, and there gas not been a system that does a better job than the Cube. And what's real nice it works that we'll on the hard rock stuff we do as well. I tell all my buddy's about it. Just wanted you to know what a quality product you have. Thank you."
Which is Better: 4 Stack or 3 Stack? There are several factors to consider: price, size (footprint), and the type of gold you may encounter. The following advice is direct from Mike, inventor of the Gold Cube... Many gold prospectors with the typical sluice box witness very flat gold (glitter gold) that has the tendency to drift or “sail” over riffles. Flat gold lends itself to slight current manipulation and water surface tension that may allow it to float. The Gold Cube design eliminates surface tension in what we call the “G-Force Separator”, which forces everything below water under a gate. This breaks the surface tension and forces the gold to the bottom of an axial trough. The combination of gravity and hydraulic pressure makes it impossible for the gold to float or sail. To illustrate this — if you were to drop a flat washer and a steel bearing, both weighing the same, into a swimming pool at the same time, the steel bearing would hit bottom, first. In the same way, the flatter the gold; the more time it takes to settle. Location is not the only factor to be aware of, though we have found that there are areas where the gold is typically very flat. Keep in mind, it is all about the shape of the gold, and not where it is located. Many placer areas close to the source have gold that is chunky, roundish, and not flat. If you plan to limit your mining to this type of area, then a 3 Stack may be your machine. You can add a tray, later, if you decide to go to the beach or find a tailings pile with super-fine gold. The beauty of the Gold Cube is that you can always add a tray, trommel, or a Gold Banker, or a Nugget Zone when it becomes necessary.
