Copper Mining and Processing Processing Copper Ores
A. Processing of Oxide OreB. Processing of Sulfide OreC. Recycling CopperOxide ores are generally processed using hydrometallurgy. This process uses aqueous (waterbased) 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 chemical solutions to leach out metals. Heap leaching is very commonly used for lowgrade ore, which would otherwise not be economical to send through a milling process. Following mining, tra Chat
