Producing Copper Nature's Way: Bioleaching

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.احصل على السعر
