• Copper Mining and Processing: Processing of Copper Ores

    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 differentThe Advantages of Recycling Copper Sciencing,The more copper recycled, the smaller the need for copper mining. Copper mining involves the usage of time, energy and fossil fuels. According to the Copper Development Association, the United States has no need to import copper. This is mostly due to copper recycling, which provides 95 percent of the copper for domestic usage.
