Copper minerals and ore are found throughout the Earths crust. They occur in both sedimentary and igneous rocks. The outer 10 km of the crust contains 33 g of copper for every tonne of rock. This is not enough to make it commercially viable to extract the rock
Malachite or green copper ore CuOH 2 CuCO 3 is an important carbonate ore as is aurite or blue copper carbonate CuOH 2 2CuCO 3 . Other ores include tennantite boronite chrysocolla and atacamite. In addition to the ores themselves several other chemicals are often used to process and refine copper
The host rock of the ore bodies is mainly volcanic welded breccia Fig. 4f with minor hosted in the marlstone. Parts of the ore bodies are affected by structure activity and occur on the west side of fault F21 which forms the contact with the goldcopper ore body on the east side of this fault Figs. 3a b and 5. The sulfur deposit is
The copper ore has to be dug from the ground. The ore contains some copper mineral and lot of waste rock. The copper mine in picture 4 produces 6 tonnes of copper from every 1000 tonnes of ore. Extraction An ore has to be changed chemically into the metal. This process is called reduction
This summer we made several experiments reducing malachite copper carbonate to genuine copper with blowpipes in open fire pits. Now we know that it is MultiElement Analysis of Copper Ore with the Avio 200 ICPOES Learn more today

202041The Copper Queen Mine was a copper mine in Cochise County Ariona United States. Its development led to the growth of the surrounding town of Bisbee in the 1880s. Its orebody ran 23 copper an extraordinarily high grade. It was acquired by Phelps Dodge in 1885. In the early 1900s this was the most productive copper mine in Ariona
Silver Silver is generally found in serpentine trap sandstone limestone shale or porphyry rocks the gangue being quart calc fluorite or silver ores are heavy and many of them are sectile may be cut with the knife. Western men test for silver by heating the ore and dipping it
Aurite is a very popular mineral because of its unparalleled color a deep blue called aure hence its name. Aure is derived from the Arabic word for blue. The color is due to the presence of copper a strong coloring agent and the way the copper chemically combines with the carbonate groups CO3 and hydroxyls has been used as a dye for paints and fabrics for eons
Picture 4 shows the distribution of these deposits. About 80 of all copper extracted comes from sulphide ores. A typical ore contains only to 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
Ore deposits are rarely comprised of 100 orebearing minerals but are usually associated with rockforming minerals during the mineraliation process. These associated minerals or rocks having no significant or low commercial value are called gangue minerals. Pure chalcopyrite having Cu metal in copper deposit and sphalerite with 67 Zn metal in inc deposit are hosted by quartite
Besides as compounds of copper are different in different ores so the process of smelting is also different. Let us consider the malachite the most commonly found ore in the earth consisting of copper carbonate. To separate the copper from it at first the part of carbon has to be driven out. Copperoxide will be obtained as a residual deposit

The mineral Aurite is dark blue in color and soft. It is obtained by the weathering of the deposits of the copper ore. Its other name is Chessylite acquired from the ChessylesMines region adjacent to Lyon in France. Aurites blue color is extraordinarily distinct and dark. Chemical Formula. The chemical formula of Aurite is Cu3 CO3 2

Bornite has a brown to copperred color on fresh surfaces that tarnishes to various iridescent shades of blue to purple in places. Its striking iridescence gives it the nickname peacock copper or peacock ore. Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite
Aurite is a secondary mineral that usually forms when carbondioxideladen waters descend into the Earth and react with subsurface copper ores. The carbonic acid of these waters dissolves small amounts of copper from the ore. The dissolved copper is transported with the water until it reaches a new geochemical environment
Ore is rock that contains economic amounts of a particular element gold ore iron ore molybdenum ore or praseodimium ore. In contrast rock that is not judged to contain economic quantities of an element is categoried as waste rock. The metals in ore can occur in many different minerals compounds in the rock. As an example copper
Sedimentary Copper Deposits Investing News Network May 12th 2011 Not all metal deposits have igneous origins sedimentary deposits can also be a valuable source of many metals including copper
Small flecks and particles embedded in ore veins in rock often together with quart silver come into contact with favorable carbonate rocks such as limestone or dolomite. Above Ore Deposit information relating to the Images and the images
Sometimes the silicified rock even replaces the original country rock. While historically speaking vein deposits were the most productive these disseminated deposits currently yield much of the worlds gold ore. Within gold ores the element occurs in nature chiefly as native gold which is by far the most common gold bearing mineral
Lithium is also extracted from ore processing although the production is not comparable to that of Chiles ndida copper mine. In Australia Greenbushes the worlds largest hard rock lithium mine currently produces about 80 kilotons one thousand metric tons of lithium carbonate equivalent annually
Bornite is an ore mineral of copper and is known for its iridescent tarnish. Peacock Ore which is sold to amateur mineral collectors and tourists is often labeled as a variety of Bornite. However most Peacock Ore in reality is Chalcopyrite treated with acid which produces a stronglycolored
THE SCIENCE BEHIND THE WET PROCESS The copper ore is mostly malachite copper carbonate CuCO 2 and aurite hydrous copper carbonate Spirit vinegar is smelly but not harmful but it is a weak acid which can dissolve the copper salts in the rock
