Copper Mining and Processing Processing of Copper Ores

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 Leaching is the process of using percolating chemical solutions to leach out metals. Heap leaching is very commonly used for low grade ore, which would otherwise not be economical to send through a
