  • Copper Mining and Processing: Processing Copper Ores

    After the copper ore is crushed, liquid is added to make it a slurry. The slurry is a mix of valuable copper ore minerals and “worthless” rock, called gangue (pronounced “gang”). The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue.

  • Copper Mining and Processing: Everything you Need to Know

    The Basics of Copper Mining and ProcessingWhat Is Copper Used for?The 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.

    The modern froth flotation process was independently invented the early 1900s in Australia by C.V Potter and around the same time by G. D. Delprat. All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite), are subjected to smelting. Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachatesolution, but this is a m

  • Copper processing Ores Britannica

    Ores Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.

    May 08, 2015· Sulfide-ore copper mining is a risky type of mining that has never been done before in Minnesota. No matter the method, sulfide-ore copper mines proposed near the Boundary Waters would extract trace amounts of metals from large volumes of rock. Rock is blasted from pit walls and sorted into metal-bearing ore and waste rock.

    Copper is mined and extracted from copper ores. To extract the metal from the ore, the rock is melted at a temperature greater than 900°C, which requires a lot of energy. Extracting metal from rock is so energy intensive that if you recycle just 40 aluminum cans, you will save the energy equivalent of one gallon of gasoline.
