methods used for extraction of copper

The Extraction of Copper Chemistry LibreTextsExtracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (\(CuFeS_2\)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

Copper extraction OverviewHistoryConcentrationFroth flotationHydrometallurgical extractionSulfide smeltingCopper extraction refers to the methods used to obtaining copper from its ores. The conversion of copper 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. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals, the ore is crushed an

Copper Processing InfoHouseIn cementation, the acidic solution of copper is deposited on to scrap iron in an oxidationreduction reaction. After sufficient amounts of copper have been plated, the copper is further refined using the pyrometallurgical process. However, this process is rarely used. Solvent extraction is more commonly used to refine copper.
