  • Copper Mining and Extraction Sulfide Ores

    It’s hard to imagine a world without copper We rely on copper for power, lighting, heating, communications, water supply and transport Copper makes our homes, schools and businesses efficient, comfortable and decorative and it lasts for many years In this esource, we’ll look at the ways of extracting copper from the groundMost of the copper ores mined today are oxide or sulfide ores Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important byproduct of this process is used for the extraction of oxide ores Pyroprocessing Sulfide Ores Provides Acid for LeachingCopper Mining and Extraction: Oxide OresFire refined copper; The correct order is: Ore (025 to 05% copper) Concentrate (30% copper) Matte (5070% copper) Blister (98% copper) Fire refined (99% copper) Anode (99% copper) Cathode (9999% copper) 2 Use a periodic table to find the atomic masses of the elements in cuprite and chalcocite Then work out the percentage of copper in eachCopper Mining and Extraction: Sulfide Ores Answers

  • 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 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 Concentration of Ore: The ore is crushed into a fine powder and aIn electrowinning there is no copper anode The electrolyte contains copper ions with minimal impurities The precious metals are left in the leach pad and not recovered This chart shows how sulfuric acid is used to extract copper The main difference between this and the ‘pyroprocessing’ of sulfide oresCopper Mining and Extraction Oxide Ores AnswersCopper Mining And Processing Resources And Glossary For copper oxide ore electrowinning is the final stage in the process of hydrometallurgy in which concentrated copper solution from the heap leaching and solvent extraction processes is used as an electrolyte an electric current is applied through an inert anode resulting in the plating of copper onto 999 pure copper cathodesCopper Mining And Copper Ore E Traction Knowledge
