Turning Copper Ore into Copper: What are the Processes?
The process of extracting copper for its ore is quite complex and varied. It largely depends on the type of ore in question, particularly whether it is a sulfide or oxide type. Copper mining has typically been performed through open-pit mining, where stepped benches are dug deeper and deeper into the ground over time. To remove the ore, …

Copper Mining and Processing: Processing Copper Ores
Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leachingis the process of using percolating …
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 …

An Introduction to the Chemistry of Metal Extraction
Instead, the usual ore of aluminum is bauxite - which contains from 50 - 70% of aluminum oxide. Copper is much rarer, but fortunately can be found in high-grade ores (ones containing a high percentage of copper) in particular places. Because copper is a valuable metal, it is also worth extracting it from low-grade ores as well.
