exploited native copper from discovery of float copper (7). When they saw unusual colored "stones" in stream gravels or on the surface, they gathered them up and experimented on them. The loose copper pieces were formed into shapes by hammering but cold hammering would have made the copper brittle. They discovered ing usfire to anneal them which facilitated them making native copper objects ...

system to leach gold over copper from oxidised ores has been tested successfully using different gold–copper ores (Drok and Ritchie, 1997; La Brooy et al., 1991; Muir et al., 1989). However, this system in the treatment of transition or sulphidic ores gave poor gold recovery and required higher reagent concentrations (Muir, 2011). Moreover, both

Float copper or drift copper is native copper that was plucked from the bedrock by the continental glaciers. When the glaciers melted at the end of the Pleistocene, pieces of native copper were left behind, buried in the glacial drift, the rock material that had been carried in the ice and which was dumped as a moraine sheet when the ice front retreated.
