• Copper Mining and Processing: Processing of Copper Ores

    Oxide and sulfide ores undergo different processes to be purified into 99.99% pure copper. 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

  • Copper Mining and Processing: Everything you Need to Know

    The Basics of Copper Mining and ProcessingWhat Is Copper Used forThe Copper Mining ProcessMined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today’s compact mining equipment, copper ore is extracted from the mine.After the ore is crushed, it’s roasted, which helps to convert sulfides to oxides. The oxides are smelted to produce matte, which then undergoes several refining processes.

    Mineral processing can involve four general types of unit operation: comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smalle

    Mineral processing can involve four general types of unit operation: comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smaller the particles processes, the greater the theoretical grade and recovery of the final product, but this however is difficult to do with fine particles as they prevent certain concentration processes from occurring. Comminution is particle size reduction of materials. Comminution may be carried out on either dry materials or slurries. Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition. Compression and impact forces are extensively used in crushing operations while attrition is the dominant force in grinding. The primarily used equipment in crushing are-jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant. Crushing is a dry process whereas grinding is generally performed wet and hence is more energy intensive. Sizing is the general term for separation of particles according to their size. The simplest sizing process is screening, or passing the particles to be sized through a screen or numb

  • Copper extraction Wikipedia

    The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using mineral flotation.
