 I just got a heap of dirt from the outdoors!
Well actually, it isn't just dirt. I found it in a construction yard where people left iron equipment in the rain for a month. Iron oxide powder, looks pretty pure, very fine. I got about 3 kg. Now I'm wondering if I should ensure the purity of it, is extracting it with a magnet worth it, or shouldn't I bother? Do the ingredients for thermite need to be super pure?

Well, if its 50/50 dirt that's one thing, but if its 5% dirt that's another. Is super pure required? Not nearly. |

Re: I just got a heap of dirt from the outdoors!
use a magnet and wash to remove salts and use a magnet again ...
i find it easyer to simply stick the earth in a bucket with a hose in it usally a 5 gallon in my case and turn the hose to fill then turn it most the way off just enough stir up the bottom a bit and over fill then i smashed a hard drive took the high power magnet out put a bag over it and attached a string and swung around the inside of the bucket.... most the earthy mud gets washed out and the iron in the water moves around and should goto the magnet once out ... just pull the bag off the magnet over some paper .. and put under a hot 100 watt bulb or somthing and dry out

Re: I just got a heap of dirt from the outdoors!
A little bit of dirt really doesn't do anything to your thermite, maybe make it a little harder to light ... you won't be able to use it for welding, but I doubt that was what you were planning to use it for.
