    Copper extraction techniques refers to the methods for obtaining copper from its ores This conversion consists of a series of chemical, physical, and electrochemical processes Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors As in all mining operations, the ore must usually be beneficiated (concentrated) To do thisA process for the extraction of copper from a copper ore or concentrate comprises first subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure in the presence of oxygen and water to obtain a resulting acidic leach liquor which contains dissolved copper The acidity of the resulting acidic leach liquor is then reduced by affecting percolation leaching ofUSA Hydrometallurgical copper extraction processThe process used to treat sulfide copper ores begins at the mine site, where the copperbearing minerals are physically separated from the rest of the rock The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining The smelting stage gives the name pyroprocessingCopper Mining and Extraction: Oxide Ores
