The Gall-Copper Process was recorded as being used during the Song Dynasty 960-1271AD. Copper was precipitated from solution by dipping iron into the blue vitriol solution - a process identified as early as 150 BC in China. 6 Therefore, presumably, the recognition of a natural copper leaching process can be identified as early as that date.
