Aug 30, 2017· Muriatic acid is a very strong corrosive chemical that can damage surfaces; avoid spilling the chemical onto other items. Step 3 Observe the reaction of the gold once the muriatic acid comes in contact with it. If the metal dissolves completely, then it isn't gold. If some of the metal dissolves, then the gold is not pure, or is mixed with

Nov 19, 2009· If the acid solution containing the dissolved gold is murky, it may contain particles and should be re-filtered with a finer grade paper filter. 6. Slowly, add the water/urea (urine ) to the acid solution containing the dissolved gold. The acid solution containing the dissolved gold will foam with the addition of the water/urea (urine).

Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (H 2 SO 4), water, and hydrogen peroxide (H 2 O 2), used to clean organic residues off substrates. Because the mixture is a strong oxidizing agent, it will remove most organic matter, and it will also hydroxylate most surfaces (add OH groups), making them highly hydrophilic (water-compatible).

Oct 15, 2016· Using only the HCl acid (muratic) will normally breakdown the rock/silca which encases the gold. but HCl is also used to remove/dissolve the base metals associated with plated gold.
