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

What is copper? Copper is an essential trace mineral, present in all body tissues, which plays a role in the formation of connective tissue, and in the normal functioning of muscles and the immune and nervous systems Why is copper necessary? The human body requires copper for normal growth and health Copper, along with iron, is a critical

About 80 of all copper extracted comes from sulphide ores A typical ore contains only 0 5 to 2 0 copper It is a measure of the value of copper that it is worth extracting it from such small concentrations The ore is a mixture of minerals and rock called gangue The most common copper minerals are:

Copper is an essential mineral that benefits bone, nerve, and skeletal health Therefore, although it is not that common, a copper deficiency can actually harm the body in multiple ways

market, demand for mineral commodities, including copper, has increased In the past 20 years, the Andean region of South America has emerged as the worlds most productive copper region In 2007, about 45 percent of the worlds copper was produced from the Andes Mountains the United States produced 8 percent

Jackling became known as the "father of Utah copper mining," and Kennecott became an important worldwide producer Jackling demonstrated that the mining of low-grade ores, containing only two percent copper, could be economically feasible when mined and processed in mass production

Percentage Amount in the Human Body: 0 0001 Sources Copper is a common element in many minerals and sometimes occurs in pure, native form Most of the worlds copper comes from the minerals chalcopyrite and chalcocite Chrysocolla and malachite also are mined for copper

Copper is an excellent conductor of electricity Most copper mined today is used to conduct electricity - mostly as wiring It is also an excellent conductor of heat and is used in cooking utensils, heat sinks, and heat exchangers Large amounts are also used to make alloys such as brass copper and zinc and bronze copper, tin, and zinc

Copper Ores natural mineral formations containing sufficient copper to make economically feasible the extraction of the metal from these ores Of the 170 known copper-bearing minerals, 17 are currently used on an industrial scale: native copper, Cu bornite peacock ore, Cu5FeS4 chalcopyrite copper pyrite, CuFeS2 chalcocite copper glance, Cu2S

Copper is found in various foods, including organ meats especially liver, seafood, beans, nuts, and whole-grains Additional copper can come from drinking water from copper pipes, using copper cookware, and eating farm products sprayed with copper-containing chemicals

Importance of Copper: Copper Benefits and Signs of Copper Deficiency Copper is an important mineral because it benefits the health of our bones, nerves and skeletal system Its also essential for the production of hemoglobin and red blood cells, and its needed for the proper utilization of iron and oxygen within our blood

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
