    The "GallCopper Process" was recorded as being used during the Song Dynasty (AD). 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.

    Heap leaching is a metal extraction process from low grade ores where crushed ore is stacked on an impermeable pad and irrigated from the top with a solution of chemical reagents. An enriched solution containing the targeted metal is collected at the bottom. This technique involves complex chemical/electrochemical reactions and transport processes. Among the main features of this method .
