Over kill for sure! a rare earth magnet of a handy size (bought online)would do just fine and put it into a medicine bottle to keep the magnetic material off the magnet. Just shake it up-n-down to drop the material. OR just go to any mining supply shop and buy one.

Never throw away what you take a magnet to. Think of a oreo cookie with the two black halves as black sands and the center as your gold. The stronger the magnet the more gold you will capture this way. Just run through a sluice or some concentrator prior to disposal-Roses are iron loving plants-and see what gold was wedged in between.

Indeed. Crush or crack and pan separately if you want to be thorough.

Otherwise just let it dry, separate it again, making the iron sand jump up to the magnet (so it leaves the non magnetic material behind in the pan) and pan out what's left. Toss the magnetic in your garden knowing there's still a little gold in there :(

I use Rare earth magnet and run it under your gold pan to move the black sands around.

Then I use a garret magnet to move the sand back and forth in two containers so I can see if any gold was stuck and use tweezers to pick out the gold that went along for the ride and what's left is us usually non magnetic material.

I save the black sands in bucket to be processed when I have enough to heat crack or melt down and send to refiner to deal with...

My goal is to have a 5 gallon bucket to heavy to lift with black sands by the time I'm retired

I clean the magnetite about 4 times and pan the dregs. Magnetite then goes to the blacksmith for making crucible steel.

I built a "magic wand" from an acrylic tube, rod, and sheet, and 3 Nd magnets. I use a piece of 1/8" silicone gasket to make a baffle around the tube to prevent sand from riding up.

I recently came across the magnetic half of an aquarium glass cleaner. Made a cradle to be able to peel off the sands. Works great.

A good super magnet ranging from the size of a dime to quarter sized, a 3 inch X 1/8 inch bolt and a 35mm film cassette will make up a great tool for removing those magnetic sands.

Simply make a small hole in the lid of the cassette lid and run the bolt through it. Put a nut on the end of the bolt and tack it in place with some super glue and set the magnet on it. Snap the lid onto the cassette (with the magnet inside of course) and you're ready to rock n roll. Run the contraption over your cons till it's covered with the magnetic sands then pull up on the bolt to release them into your holding container.

When I'm using my magnet, I prefer to do it with about an inch of water in the pan. Draw the magnetic sand up through the water to the magnet. This washes the sands and helps to keep the gold on your pan instead of allowing it to be trapped. When finished I dry the sands and go though them again with the magnet in small amounts. Anything that is left gets run through my rod mill and then cleaned yet again. I've been able to pull out quite a bit of micron sized gold this way. Remember... It may be small, but it all adds up!

I modified an old lip stick and glued a small Neodymium magnet inside.
Quite handy in my pockets when i prospect with light equipment :)

I use a cow magnet, you can get them from the farm store or might kick a few cow pies'
I slide off the black sands easily with my index finger wrapped around it.

Keep the magnetite in water when cleaning it of other material. Otherwise it gets dusty, and you don't want to breathe it. (be wary of silicosis, blastomycosis, or valley fever) Clean the magnetite about 4-5 times to get most of the junk out, and take small bites with the magnet. Work the magnetite and make it move around before letting it jump to the magnet. That helps to make it drop the junk. Also stratify it between cleaning steps to help it drop material.
