Ok so I have been puttering about with this for the last couple weeks. Working on refining a technique and the quality of where I get my gold metal plated scrap shit jewellery.... and so I did the following.
Nitric acid to remove everything. Dilution and filtered to catch every piece of undiluted gold. Multiple nitric baths to remove material till it didn't react. Using water between steps. I get left with what looks like a spoonful of gold flakes and organic matter. I create a solution of aqua regia and bam it all dissolves. I filter it off. Nice golden yellow. And the inorganic dissolvable crap is left. Little peices of random glass base particles. Exactly what I expected. So I add potassium metabisulfite and bam... nothing. Goes dark then back to yellow ish pale fluid... no precipitate... do I keep adding more? I feel like I've added too much by now. Or what do i do......
