Thorium chloride extraction.
Could I produce thorium chloride from lantern mantles by burning them to ashes, producing a mixture of oxides and ashes, then react the mixture with
hydrochloric acid to produce thorium chloride? I have about 200 mantles.

No, since you will form ThO2 wich is very inert.
It´s only shlightly soluble in hot conc. H2SO4.
But you could reduce the ThO2 to Th metal and disolve it in HCl.

Ahh. That is so much easier to type than to do.
I recommend reading the thread by Dan Vizine on the trials of thorium production.

Can´t you just reduce it with lets say Mg powder like:
ThO2 + 2 Mg --> Th + 2 MgO ?

Calcium. Inert atmosphere. High temp.
Read the thread.

In the Holleman Wiberg(best book of inorganic chemistry in austria) is written that ThO2 would react with CCl4 or AlX3(X = Cl, Br or I) at higher
temperatures to ThX4

Ok, thanks. Could I reduce it with lithium? I can't find a figure for how much ThO2 would be in a single mantle, but I guess around 1/8 gram.

I think so.
Btw are your mantles used?
When not, couldnt you just soak them in water sinc they are made with Th(NO3)4 and get the salt?

Good point. I was going to burn them because I thought the oxide would be more useable.

Also often they contain up to 1% Ce(NO3)4

Does anyone know if a carbonate leach (like is often used in uranium chemistry) could be used on the ThO2?
