    07/06/2021· 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 copperTry this page from The Essential Chemical Industry as a starter The end product of this is called blister copper a porous brittle form of copper, about 98 995% pure Exploring the redox processes in this reaction It is worthwhile spending some time sorting out what the reducing agent is in these reactions, because at first sight there doesn't appear to be one! Or, if you lookcopper extraction and purification chemguideCopper Smelting: Smelting is a metallurgy technique to extract base metals from their ores with the help of heat and a chemical reducing agent (Click here for extraction process) Copper Smelting means that the concentrated ore is heated strongly with siliconExtraction Of Copper | Mining, Concentration, Smelting
