    Extracting of Copper from Other Ores Copper can be extracted from nonsulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solutionThe principal ore of copper is copper pyrite and copper is extracted from this ore The different steps in extraction of copper are: Crushing and Concentration: The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized The ore being sulphide ore is concentrated by froth floatation processExtraction of Copper from Copper pyrite | Grade 12 Science

  • Extraction Of Copper | Mining, Concentration, Smelting

    Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulfides 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 Concentration of Ore:Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore Open pit: 90% of ore is mined by this method Ores near the surface can be quarried after removal of the surface layers The ore is treated with dilute sulfuric acidCopper Mining and Extraction Sulfide Ores

  • Copper Mining and Processing: Processing of Copper Ores

    Copper oxides are more abundant near the surface, but are considered lowgrade ore, with a lower concentration of copper Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit On the other hand, while copper sulfide ores are less abundant, they contain higherThe finely crushed ore is concentrated by Froth EXTRACTION OF COPPER IMPORTANT ORES OF COPPER Copper pyrite or chalcopyrite (CuFeS 2) Chalocite (Cu 2 S) or copper glance Malachite green [CuCO 3Cu(OH) 2] Azurite blue [2CuCO 3Cu(OH) 2] Bornite (3Cu 2 SFe2S 3) or peacock ore Melaconite (CuO) etc EXTRACTION OF COPPER FROM SULPHIDE OREEXTRACTION OF COPPER
