Copper Mining and Processing Processing Copper Ores

Oxide 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 oChat

Copper Mining and Processing Life Cycle of a Mine

Prospecting and ExplorationDevelopmentExtractionClosure/ReclamationProspecting and exploration are precursors to mining and often occur simultaneously; together, they can take two to eight years to complete, and may cost from 500, to 15 million overall. Prospecting is the process of searching the region for mineral deposits. Historically, prospectors would explore a region on foot with a pick and shovel. Modern prospecting uses a variety of geological methods. Geology experts use a direct method to discover surface mineral deposits by examining the aChat
