Three nines possible with Poor Man’s solutions?

[Juan-2-many]

Hi friends,
I read in a Reddit thread that neither poor man’s nitric or poor man’s AR should be used when the goal is to refine to three nines or higher.

Is this true? What do these methods leave behind that won’t refine out?

I personally was planning on poor man’s nitric for some things and AP for others.

There is no reason you can't achieve three nines using the poor man's work arounds. Members here do it all the time.

I'd trust what you read here over what you see on Reddit.

I was wondering why I couldn’t find anything on the subject while searching.

So why does everyone prefer AP over poor man’s nitric if poor man’s nitric is faster? Not that we’re trying to win a race or anything…

Agreed with Dave, Pucky!

It may be more tedious but very possible.

As dave quite correctly said of course it's possible. The trick is in the cleaning!

Poor mans Nitric means making it by mixing the Nitrate and the Sulfuric, then either freezing it and removing some of the salts and using it as is.
Or Distilling it and get pure acid.
When we use AP it is just straight forward and no need for extra steps, and it do not create Metastannic acid.
