Ask United Nuclear for one of their ridiculously powerful Neodym. monsters, that might take care of the iron for you.

I know people pull iron ores out of sand using the same idea.

You'd obviously want it as finely dispersed as you could get it, perhaps by dissolving it and then re-extracting.

Honestly though, as much as I hate the unnecessary fear surrounding these kinds of things, I'd still be wary of powering even the ore to a fine particulate and the possibility of it getting into the air.

A half face respirator with a P3 or something on it might be an idea. But that's prevention rather than cure, I wouldn't want it hanging around all over the place to start with.

It won't be hard to check if that's necessary, just check what the guys in the mines & refineries wear if there's dust around.

Uranium ore from Amazon

Amazon is selling small tins of uranium ore. Please, please, do yourself a favor and read the reviews; they almost constitute a genre.

Almost as funny as the reviews (now removed) for the book by Martin Wank entitled "Sex, Freud and Folly: The Truth About Psychotherapy" eg "Wank has a firm grasp of his subject"

If you happen to live in or around Montana or the Appalachians, you're in luck.

Hmmmm... Looks like there are two small red dots in my area... I wish there were highly detailed maps I could get my hands on. Perhaps going to the geology department of the nearest University might lead you to some information regarding local U deposits.

Also, although my state is not well known for uranium deposits, I found a paper published almost 50 years ago that gives a very detailed description of a location with an anomolously large amount of "highly concentrated" uranium ore.

Just keep on looking (those of you that are interested in finding ore). I find this very fascinating (the potential of "proscpecting" for U ores).

I made a webpage about solutions and precipitates of uranium compounds. Its chemistry is quite interesting and I think it would be nice to share with others:

Notice that most of the argument against uranium is that you wouldn't eat it?

These are people who NEED to eat it.

A UVA (black light) will help in the abandoned mines, but really, mostly what you'll get is composed of U238, and not the fisible 235 isotope. In fact, I believe Yellow Cake itself is used in the pottery/glazing business. Until recently, the refined ore represented the naturally occurring isotopic distribution. But now, almost all ceramics grade pigment has already been processed by one of our national plants to remove the valuable 235. And this process is one of the reasons U235 is so expensive. Also, the necessary closed loop controls make control of heroin & cocaine look like a walk in the park. Trying to acquire uranium, even depleted, is likely one step worse than making meth, counterfeiting greenbacks (or whatever colors hey are now), and(or) being a pedophile child molester sexual baby predator.

I can only assume he was talking about pure U235 (which I still think would be a cool thing to have in an element collection!) If you could pull that off (getting a sizable amount) you wouldn't be posting here and you'd be rich; and possibly also an accessory to mass murder.

Well, I don't know... Maybe you would post here...

Depleted is not pure U235. But you knew that.

Just be aware that the chemistry of uranium has hazards as well as the radio-chemistry hazards. Even the fine particles of U238 (stable isotope) are regarded as possible problems with acute human contact.

Contrabasso, I agree about U toxicity, but amateurs do perform uranium chemistry without serious problems.

Yes, I also did some home chemistry with uranium (I posted a web page about that a few days ago), such as reducing it to lower oxidation states and testing its fluorescent properties. I now made some of the formiate, which is not fluorescent.

Uranium salts are toxic, but not as toxic as salts of e.g. mercury, lead and cadmium.

My starting material is some powdered uranium oxide (a dark green powder, mostly U3O8, UO2 and maybe some silicate material in it as well). I think it is crushed pitchblende ore. It dissolves fairly easily in 50% nitric acid, when the acid is heated. Some insoluble crap remains (the silicate stuff) and with H2O2 I can precipitate the uranyl content of the solution. Then I have the material for further experimenting.

Btw, the posted link is a fantastic one. This is really nice home chemistry. Everything (except maybe the last step of reduction to metallic uranium) could be done by even a moderately equipped home chemist.

You're right, I just chose to assume he didn't know what depleted U was.

Yes, the fall semester just started last week. I will be taking one chemistry course (damn scheduling conflicts), a physics course, a math course and a programming course. Also, a couple of hours of undergrad. research in chemistry and possibly physics. Details are in U2U.

This guy here has 3g of depleted uranium for sale for like \$55.
Just found it while lurking through ebay. It looks of a decent size.
