Next, to extract copper from Copper Oxide [ce{Cu2O}], Aishu can use a reduction reaction, typically involving carbon (in the form of coke). The reaction can be represented as: [ce{2Cu2O + Cu2S -> [Heat] 6Cu(s) + SO_2(g)}] Combining both reactions, Aishu successfully extracts copper from both compounds. The overall process involves ...

Heap Leaching
Heap leaching is the most important method of hydrometallurgical copper extraction. Heap leaching is used for treating oxide and lower-grade secondary sulfide ores that contain up to ∼2% Cu. The ore is crushed to a uniform particle size (typically 12–50 mm), often agglomerated, and then stacked on large flat-topped heaps in a controlled manner.. Heaps are typically ∼7 m high …
