Refining advice

[MD]

I have some electronic boards. I'd like to remove and refine the gold. I'm attempting the aqua regia method, but am having a hard time developing or finding a local dealer for the nitric acid. Anyone care to offer advice? Is there an easier way besides aqua regia?

My friend unless you are very serious and have a good number of boards I would melt everythibg to gether and send if off cuse the Nitric Acid will cost you $45.00 HAZ-MET SHIPPING COST. That is for 1 gallon.

Here is a link for the 'recipe'. Beware that it is apparently very dangerous to produce and use.

I saw a post on this forum with links to chemical supplies for gold processing. Sodium nitrate. Sulfuric acid etc. That totse is not a reliable source.
