copper ore process by hydrometallurgy

2 Hydrometallurgy is the recovery of metaIs from ores using waterbased solutions As early as 6000 B C native copper–the pure metalwas foundas reddish stones in the Med iterranean area and hammered into utensils weapons and tools Around 5000 B C artisans discovered that heat made copper more malleable
