Newbery–Vautin chlorination process - Wikipedia

The process of extracting gold from ores by absorption of the precious metal in chlorine gas, from which it is reduced to a metallic state, is not a very new discovery. It was first introduced by Karl Friedrich Plattner around 1848, and at that time promised to revolutionize the processes for gold extraction.
