    Copper - Wikipedia

    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). These minerals are concentrated from crushed ores to the level of 10–15% copper by froth flotation or bioleaching.

    Innovations: Introduction to Copper: Mining & Extraction

    The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

    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.

    Jul 16, 2004· Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved.
