  • Copper Mining and Processing: Processing Copper Ores

    Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 9999% pure copper called cathodes, which will ultimately be made into products for everyday useThe most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively,Yellowcake (also called urania) is a type of uranium concentrate powder obtained from leach solutions, in an intermediate step in the processing of uranium oresIt is a step in the processing of uranium after it has been mined but before fuel fabrication or uranium enrichmentYellowcake concentrates are prepared by various extraction and refiningYellowcake WikipediaBiomining is the technique of extracting metals from ores and other solid materials typically using prokaryotes, fungi or plants (phytoextraction also known as phytomining or biomining) These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electronsBiomining Wikipedia
