13.5.7.3 Flotation of Copper Ore. Copper ore usually contains about 0.5 to 2% copper that occurs in the form of disseminated and stringers. The run of mine ore is reduced from The concentration of copper in ores averages only 0.6%, and most commercial ores are sulfides, especially chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4) and, to a lesser extent, covellite (CuS) and chalcocite (Cu 2 S).

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 In recent times, a low copper content in ores has been observed (ores containing 0.2–0.3% copper are used for processing in Canada and the United States, and ores containing at least 0.4% copper are used in Russia []) owing to the exhaustion of rich copper resources.The flowsheet of processing copper ores is developed for each Current Status of Copper-Ore Processing: A Review

The first exploited ores were copper oxides such as malachite and azurite, over 7000 years ago at Çatalhöyük. These were the easiest to work, with relatively limited mining and basic requirements for smelting. It is believed they were once much more abundant on the surface than today. After this, copperThe copper ores from El Teniente and Andina mines are mainly composed of chalcopyrite (86%–90% and 81%, respectively) [57,58]. It is worth highlighting the presence of molybdenite in Chilean minerals, such as in El Salvador, Andina and Escondida mines, making Chile one of the world’s major producers of molybdenum .Chemical Composition Data of the Main Stages of Copper MDPI
