Chapter 6 Copper Production Technology

2 Hydrometallurgy is the recovery of metaIs from ores using water-based solutions. As early as 6000 B. C., native copper–the pure metal—was 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 malle-able.
