Usingonly the HClacid(muratic) will normally breakdown the rock/silca which encases thegold. but HCl is also used to remove/dissolve the base metals associated with platedgold. And then further refined by placing thegoldrecovered into a solution of HCl and bleach, which will dissolve thegoldinto the solution.

Feb 23, 2011· The methods to dissolvegold using muriatic acidand bleach have been discussed at length including proper safety and mixing techniques. Here's one of many such posts:UsingHCl-Cl to DissolveGoldTheuseof ferrous sulfate (copperas) as a precipitant forgoldhas also been discussed at length. It needs to be fresh to work properly.

Alchemy? Whenusingnitricacidto remove base metals ingoldrecovery it is very easy to misplace yourgold. On electronics thatuse goldfor shielding (such as RF shielding) thegoldcan be very thin and instead of coming off in foils will separate into finely divided particles and will get lost in trash.
