Perhaps one of the most desirable qualities of gold – especially to those wearing it as jewelry – is its ability to hold onto its bright, shining glow. Gold can resist rusting and tarnishing when exposed to air or water because it's inert, meaning it's one of the least reactive of all metals. But gold has some unexpected properties, too.

The use of thiosulfate to extract gold from refractory ores is promising because of its non-toxicity and high selectivity. Sulfide minerals (i.e., pyrite, arsenopyrite, chalcopyrite), major gold carriers in refractory gold ores, however, hinder gold extraction due to the high consumption of a lixiviant. In this study, a new method to improve gold …

The ore is first converted into pure aluminum oxide by the Bayer Process, and this is then electrolyzed in solution in molten cryolite - another aluminum compound. The aluminum oxide has too high a melting point to electrolyse on its own. The usual aluminum ore is bauxite. Bauxite is essentially an impure aluminum oxide.
