    Extraction of gold and other precious metals from their ores by treatment with mercury is called amalgamation. Gold dissolves in aqua regia, a mixture of hydrochloric and nitric acids, and in sodium or potassium cyanide. The latter solvent is the basis for the cyanide process that is used to recover gold from lowgrade ore.

    Oct 20, 2014· Refractory Ores/SolidSolution Gold: In some ores, Au can be locked inside the sulphide mineral matrix of the ore (so called solid solution), and the cost for the energy required to grind and liberate is simply too high to be viable. These are "refractory ores" and require a chemical, not simply physical, process to liberate gold from the surrounding rock.
