  • Copper Mining and Processing: Processing of

    Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different

  • What ores of pure metal use sulfuric acid in the

    To start, "ore of pure metal" is a bit contradictory. Ore as a term implies that the substance is a metal-containing compound, which is why ores need to be either thermally or chemically (or both) processed in order to extract the metal. For examp
