Dissolving Gold and Precipitating Gold Pyrometallurgy
Regardless of how much gold might be present in our ore, unless the aqua regia (recommended over HCL & Bleach when dealing with ore rather than jewelry scrap) can freely react with the gold present, we will spin your wheels and get “consistently inconsistent” results that will drive us crazy.

Aqua regia Wikipedia
Aqua regia dissolves gold, although neither constituent acid will do so alone.Nitric acid is a powerful oxidizer, which will actually dissolve a virtually undetectable amount of gold, forming gold ions (Au 3+).The hydrochloric acid provides a ready supply of chloride ions (Cl −), which react with the gold ions to produce tetrachloroaurate(III) anions, also in solution.
