composition of copper ore
Copper
Most copper is mined or extracted as copper sulfides from large open pit mines in porphyry copper deposits that contain 0.4 to 1.0% copper. Sites include Chuquicamata, in Chile, Bingham Canyon Mine, in Utah, United States, and El Chino Mine, in New Mexico, United States. According to the British Geological Survey, in 2005, Chile was the top producer of copper with at least one-third oOre minerals, also called useful minerals, refer to metal or nonmetal minerals that can be utilized in ores, such as chalcopyrite, bornite, chalcocite, malachite Ore, Composition and Classification of SpringerLink

Copper Element information, properties and uses
Copper metal does occur naturally, but by far the greatest source is in minerals such as chalcopyrite and bornite. Copper is obtained from these ores and minerals by smelting, Cooling and fluid–rock interactions serve as the critical controls triggering Cu precipitation from the fluid. The combined textural and compositional data of pyrite and chalcopyrite are suggestive of a syn-orogenic copper deposit model, in which all the ore-grade copper was introduced during the Zhongtiao orogeny.Major and trace element and multiple sulfur isotope composition

Copper Ore Properties and Uses ThePipingMart Blog
Its color ranges from light blue to dark greenish-black, depending on its composition. Copper ore typically contains trace amounts of other elements such as iron, aluminum, magnesium, and sulfur. The presence of these elements imparts unique properties to copper ore which make it ideal for various industrial applications.Clogging or total blocking of tubes in the processing plant can be the result of high amounts of such alteration minerals.

Copper Facts: Chemical and Physical Properties ThoughtCo
Properties: Copper has a melting point of 1083.4 +/- 0.2°C, boiling point of 2567°C, specific gravity of 8.96 (20°C), with a valence of 1 or 2. Copper is reddish colored and takes a bright metallic luster. It is malleable, ductile, and a good conductor of electricity and heat. It is second only to silver as an electrical conductor.Copper processing Ores, Refining, Smelting: 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 Copper processing Ores, Refining, Smelting Britannica

Copper: Definition, Composition, Types, Properties, and
Copper is extracted from natural ores—either a copper sulfide ore (such as chalcopyrite) or a copper oxide ore. These ores are mined, crushed, and processed to make copper. These copper ores are found in parts of North and South America (countries such as Chile and Peru), as well as in areas such as the Ural Mountains in Russia, and The minerals are very small in grain size. Copper occurs mainly as copper sulfide with a small amount of free copper oxide, and the beneficiated copper accounts for 95.21%. Nickel occurs mainly as nickel sulfide, and some nickel silicate and nickel oxide occur in the ore. The beneficiated nickel accounts for 72.03%.Chemical composition of the ore and occurrence state of the

Copper is not difficult to extract from it ores, but mineable deposits were relatively rare. Some, such as the copper mine at Falun, Sweden, date from the 1200s, were the source of great wealth. One way to extract the metal was to roast the sulfide ore then leach out the copper sulfate that was formed, with water.
