Extract Lanthanum from Mischmetal.
1. Dissolve in HCl.
2. Precipitate oxalates, Mg and Fe will stay in solution.
3. ???
How do I separate lanthanum from cerium? I know it has to do with the ability of cerium to form an IV oxidation state, but I have no idea as to how
that helps.

Mischmetal contains more than just Ce and La: there's at a minimum a good dollop of Nd in there, probably also Pr. Separating these is a nightmare...

In 1-5% amounts, yes. Recrystallization could remove that.

You have a CoA of your metal?

No, that's just the average amount I found after some research. (I wish I knew a place with CoA's...)
EDIT: If anyone does know the percentage amounts, these are rods of mischmetal from magnesium firestarters.

Also common lighter flints. Interestinly this metal is commercially produced by electrolysing the anhydrous RE chlorides mix (in a salt eutectic).

I have a good book on the subject but it seam to be a too big document for the forum. I'm actually working on a similar project that this one and
already have good result for cerium extraction, the problem is that I'm running out of ammonium salt hence the hydrolisis of urea thread.
I never asked for this.

Plante: if you really want make some NH3 for ammonium salts production, get a NPK fertiliser and treat it with strong alkali. And crude (NH4)2SO4
garden grade you should find at any decent garden centre...

If you use ammonium nitrate, the byproduct is sodium or potassium nittrate (and we all know how much fun those are...)
