Copper can be extracted from non-sulfide 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 solution. Concentration of the copper (II) sulfate solution by solvent extraction.2 天之前Copper for its low-grade ores is majorly extracted by making the usage of the processes of hydrometallurgy. Moreover, the extraction of copper is majorly done by the process of leaching which relates to the use of bacteria. These bacteria leach out the ore and thereby extract copper from the metal compounds.Copper is Extracted by Hydrometallurgy from Low-Grade
