I've watched a few vids of this type over the years. Not my area of expertise but I found this one more interesting. Not just because of the mention of royal vodka I might add. I prefer a cold beer personally.
He reduces the gold via a different process to what Ive seen before.
Thoughts?

I'm not tryi g to cause a contradiction KarlS but up u ntil a year ago l was using nitric acid for my work on the odd occasion.
I just looked online and it does still seem to be available.

Yep, you need some sort of license to buy it. I know that high concentration stuff can be used for no good, but I only need 45% acid to refine gold. Still no go.

Bleach and hydrochloric acid works reasonably well, but gold must be in very small pieces and must not contain much silver.
