The Synergistic Copper Process concept
The Synergistic Copper Process route (Hawker et al. 2015) is one that takes advantage of complementary strengths of both the hydrometallurgical and pyrometallurgical routes, and eliminates their weaknesses. In essence, it acknowledges and utilises both the inherent advantages of the leaching of copper from oxide-based and low-grade copper ores ...

Hydrometallurgy: Processes, Advantages, …
Copper, for example, is a primary target of hydrometallurgy since it is easily obtained through electrolysis. Cu 2+ ions decrease at low potentials, leaving other contaminating metals like Fe 2+ and Zn 2+ behind.
