Saw this on Facebook today. Thoughts? Find it hard to believe it won't take micron with it, but they claim it won't

That seems like an extreme amount of magnetite, even for cons. Wow
I have a cheap spring thumb push magnet that works awesome but I don't even use it much.
Seems useful if you have bucket fulls of magnetite but who does? That's a very strange invention indeed.

I think they're using a lot of black sand just to make the point. Most interesting video is the second link where it pulls the black sand out of a snuffer bottle. If it could do that without taking any micron with it, that would be quite a handy tool! But at $120, it is an expensive experiment lol

Price point seems way too high. I can remove magnetic black sands from my snuffer bottle just as fast with my $1.25 neodymium magnet dragging it up the side of the bottle as she did. I see that it looks to work well for large volumes of concentrate which are screed out to about 2" depth. I just have never found myself in that situation. It may be worth it for large operations? Any magnet will pinch a certain amount of micron out of the concentrate and that's super easy to pan out, usually very minuscule.

Watched a bunch of videos and curiosity got the best of me, so I ordered one.

Need to get out in the creek and stop sitting at home watching videos on mining equipment ;)

I was out on CC Saturday and it was quite chilly.

Any ice forming yet?
Kjelsner
Yes. Ice is forming. From ice to ice the creek was only about 20ft wide. Stuff on near the shore was 2 to 3 inches thick.
