So I found a Jobe black sand magnet on EBay for 8 bucks so why not. I got it today and separated the magnetic sand out and found that you are all absolutely correct. Just as AZADAM said it did suck up gold even after banging it all around and repeatedly picking up and dropping the sands.
Neodymium magnets are a member of the rare earth magnet family. They are called "rare earth" because neodymium is a member of the "rare earth" elements on the periodic table. Neodymium magnets are the strongest of the rare earth magnets and are the strongest permanent magnets …

Rare Earth Magnetic Plate Separators – Cleaning. Cleaning magnetic equipment is a lot easier to do once a little forethought is applied to the configuration of your project. For example, your system could include a hinged ferro plate to allow for easy cleaning and inspection, or if your plate magnet configuration is located in a place that is ...
Since the early 2000's, art conservators have been increasing our use of rare earth magnets for all types of conservation work. The small size-to-strength ratio of these magnets has allowed them ...
Despite their name, experts say the world is not likely to run out of rare earths anytime soon. Schodde keeps a database of about 58,000 significant mineral deposits around the globe. This includes 270 rare earth deposits, plus several hundred other deposits containing minor amounts of these metals. About 30 of these are currently being mined.
The magnets sold by the most of the major prospecting shops to separate out black sands will not do. Those old style magnets will pick up magnetite, but not hematite. The new powerful rare earth super magnets are necessary because they will pick up the hematite, which is only very slightly magnetic.
25 years ago I bought a couple 'rare earth' magnets that were about 1"L x 1/2"W x 1/4" thick at an electronic surplus store. When I showed them to my coworkers they were amazed at how powerful they were. You could toss these things at a steel cabinet from 12' feet away and they "snapped" on with such force it was scary.
Black Sands Processing & Content Assaying. It appears none of the gold prospectors spend nor time or money on assaying their black sands for gold value determination. Instead, they use a rare earth magnet to tells them what is in there and see that most of the gold is magnetite with sometimes hematite. What little remains goes under the ...

I've had a lot of good results with rare earth magnets. I can get 3 to 4 times as much black sand out of my gold with them. With a little extra time I can get the gold virtually 99 percent clean, and avoid the chemicals/extra costs. If you want to try I got mine from a place called Grainger (6-7$).

Heavy Minerals Sands Processing by Rare Earth Magnets. The first known attempts to apply a REM roll separator to a heavy mineral sands application were made in South Africa and Western Australia in 1985. At that time, an ilmenite beneficiation process, which was normally achieved with cross-belt separators, was tested with a full-size machine.
Rare earth elements are an essential part of many high-tech devices. The U.S. Geological Survey news release "Going Critical" explains: "Rare-earth elements (REE) are necessary components of more than 200 products across a wide range of applications, especially high-tech consumer products, such as cellular telephones, computer hard drives ...
1. Blue Bowl Technique – This method of black sand gold separation actually works by using water in a similar fashion as a swirling toilet. It washes out the black sand and tends to keep the now cleaner gold at the bottom of the blue bowl. This is a really slick device, and is one of most popular tools out there.
Over the past decades there has been an explosion in the demand of rare earth metals, as more and more devices requiring rare earth metals rise. Devices such as computer memory, rechargeable batteries, magnet, and even defense equipment/devices such as night vision goggles, precision-guided weapons and GPS equipment require rare earth metals.
