Advantages of extraction of copper of ore

bacterial consortium for copper extraction from sulphidethe mining industry is looking forward for bacterial consortia for economic extraction of copper from lowgrade ores. the main objective was to determine an optimal bacterial consortium from several bacterial strains to obtain copper from the leach of chalcopyrite. the major native bacterial speciesus5223024a hydrometallurgical copper extraction processa 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 ofextraction of copper qs studythe extraction process involves the following steps (i) condensation of ore only 23% copper (cu) is present in copper pyrites (cufes 2 ). after concentrating it by oilfroth floatation process, the amount of cu will be 30%. copper pyrites) and similar sulphide ores are the commonest ores of copper.extraction of copper and zinc chemistry, class may , · extraction of copper. it is mainly extracted from copper pyrites (cufes 2). the sulphide ore is usually of very low grade and contains iron sulphide, gangue and smaller quantities of arsenic, antimony, selenium tellurium, silver, g and platinum. the various steps involved in the extraction are 1) crushing and concentrationcopper extraction overviewhistoryconcentrationfroth flotationhydrometallurgical extractionsulfide smeltingconcentrate and copper marketingsee also

copper extraction refers to the methods used to obtain copper from its ores. the conversion of copper consists of a series of 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). the processing techniques depend on the nature of the ore. if the ore is primarily sulfide copper minerals (such as chalcopyrite), th · text under ccbysa license and arrange in thecopper extraction academic kidsjun , 05· currently, the most common source of copper ore is the mineral chalcopyrite (cufes 2), which accounts for about 50% of copper production.the focus of this article is on the process of copper extraction from chalcopyrite ore into pure metal. processes for other minerals are mentioned. for economic and environmental reasons, many of the byproducts of extraction are reclaimed.extraction of copper mining, concentration, smeltingcopper mining the commonest ore used in the extraction of copper is chalcopyrite (cufes 2) also known as copper pyrites and other such sulphides. the percentage of copper in the actual ore is too low for direct extraction of copper to be viable. the concentration of ore is required and it is done by the froth flotation method.estimated reading time 2 mins
