copper extraction using sulfuric acid

  • Sulfuric AcidMining Health and Safety

    Sulfuric acid has many industrial purposes and is produced in greater quantities than any other chemical worldwide. In metal mining sulfuric acid is used to leach copper oxide minerals. In one process a solution of sulfuric acid laden with copper sulfate is stripped of copper via a solvent extraction and electro winning with the used sulfuric

  • Copper Mining and Extraction Sulfide Ores

    The blister copper anodes are immersed in an electrolyte containing copper sulfate and sulfuric acid. Pure copper cathodes are arranged between the blister copper anodes and a current of over 200A passes through the solution. This is driven by a low voltage of about 1.3V and so the process is safe. What happens in electrolysis
