AC Magnet / Eddy Magnet

very interesting. I don't think we have to worry about our cheap or free (from microwaves) interfering with our scrapping endeavors !! I don't think 98% of us could afford a magnet that would separate our non ferrous !

I have two Eriez pan separators, each pan performs a different type of motion. Each magnet has a rheostat where you can aggressively agitate or go to a less aggressive situation where the product on the pan barely moves.

I've only played with the one pan, put the pan on an incline, add some copper, gold and silver then depending on where you have the power set at, the gold will travel up hill until it falls over the edge of the pan into a pail or bucket.

You need to be a bit more aggressive to get the lighter silver to move up hill, to much power on the rheostat and your copper is going to come along for the ride.

Its he same as if you were using a gold pan panning by hand you get to aggressive everything you have in the pan is going over the side.

I'm working on a small eddy current drum which will be approximately 3 inches in diameter, much to small for a scrap yard but just right to recover the precious metals from ball milled integrated circuits. Where your only dealing with about 60 lbs.

My rare earth permanent magnets were recovered from junk stepper motors.

You find stepper motors in photo copiers and printers, larger one from automated machinery like CNC milling machines, lathes and cutting tables. Besides using steppers to make homemade cnc projects you can use them as generators on wind turbines.
