Request for help testing

aluminium foil

Oh I have read it. multiple time in fact. It's about as disjointed as a crash crash victim. I had done my own read reach via the library on this
forum. If you are referring to the B-Ni alloy thing. That is complete find to call it that. I have read many sources that saying that will work and
others that said no
Elements Collected: 19/81 (Excluding all radioactive, using placecard for those)
Any tips or good sources are welcome.

It may be 'disjointed' but it contains a lot more information than your post.
B-Ni alloy? The Nd,Fe,B alloy is coated with a nickel sleeve. 'B-Ni alloy' doesn't come into it.
Nd sulphate cannot be displaced with HCl.
NdCl3 cannot be reduced with Mg, Ca, Na or Li. It's thermodynamically impossible.
Via watery chemistry one obtains NdCl3.6H2O, not NdCl3.
As regards these 'many sources', I'd really love to see them! What precisely do they claim 'will work'?
I understand you're an element collector who dreams of adding neodymium to his collection. But extraction of Nd from Nd magnets is seriously
difficult at the home/hobby level and no one here has so far succeeded fully, despite good expertise and valiant efforts.

Despite claiming to have read the thread, all of what you ask has been gone over multiple times and in multiple places in said thread. Blogfast
provides a nice summary of what's wrong in your initial post. To add to that: The nickel coating does need to be removed, because the
acid won't be able to reach the magnet alloy otherwise. Also, the final reduction with a reactive metal must be done under inert atmosphere. It won't
work without one - I've tried it. I also tried magnesium to no avail. We've done the math (in the thread!) and determined that the only one that has
any hope of taking this reaction to completion with good separation is lithium metal reacting with neodymium fluoride. The chloride won't work either.
Had you read the thread as you claimed, you would know these things already.
If the thread is too 'disjointed' then do what I did and make your own summary of the things important to you as you read through it, and refer to
that. I copied out all of the actual experiments then read through that much smaller subset of posts. From there it's easy to tell what works and what
doesn't.
Finally, endlessly speculating different equations while disregarding the hard work of blogfast, myself, and others is bound to get you nowhere. How
about you go ahead and try some of these things that you are convinced will work? That would be a useful contribution to the main thread, and we would
be glad to help you there if you show some effort. The only 'equipment' you need for the first few steps is a few beakers (but it gets much more
complex after that).

MrHS:
Ooopsie. I didn't realise it was THAT DalisAndy. That guy's a whiner beyond helping and who always seems to think he knows best somehow, IMHO. I'm not
wasting my time on this (having already done that, essentially). The trouble with some element collectors is that they want to do complicated
things while knowing as much about chemistry as a cow knows about eating saffron. Harsh maybe but it needs to be said. If you really want to add pure Nd to your collection, buy some, it's not expensive
anymore.
This thread belongs in Detritus because of needless repetition. Starting multiple threads on exactly the same thing is trolling.

Hey let's have a little professionalism here. There's an unfortunate tendency of people to be a lot more confrontational in type than they would in
person. Several examples are above. It was not necessary to say his reax were all rubbish. They may have been but we could have been more helpful and
a gentle approach would be more likely to have an impact.

Professionalism ?
This is a forum for Amateur Science, or so i thought.

I agree with chemrox, just because we are amateurs doesn't mean we can drop our level of respect to a minimum. I run by the rule of if we can't act
like men, then we aren't a team

It's a Wikipedia error. Li doesn't reduce NdCl3. Check the thermodynamics on that reaction.
'Flourine'? [sic] You don't need fluorine to prepare NdF3, as you would know if you HAD read that thread.
No. He thinks he can separate NdCl3 and FeCl2 by running iced water over the mixture. It's plain NONSENSE, like so much on teh Utoobs. You just can't
separate Fe and Nd that way.
You're clueless. As is 'TheChemLife'...

This is terminally silly.
@DalisAndy
Do some experiments, Scientifically and PROVE them wrong.
Photos will help.
They're Chinese copies, so probably piss poor on the piss-proof front.

What is currently standing in the way of that
happening? Space? Money? Parents? Quite often there can be workarounds for such issues.
Until then, asking others to try procedures that they feel confident will not work and be a waste of resources will get you nowhere.

Forgive my highschool level chemistry here for a second, but I'm not sure that's correct.
Based on these half equations:
Nb3+ + 3e- -> Nb -2.32V
Li+ + e- -> Li -3.04V
The reaction Nb3+ + 3Li -> 3Li+ should have a potential of
-2.32 - (-3.04) = 0.72V
and thus be possible. Right?
