        Based on statistics in the United States Geological Survey (“USGS”) database of worldwide porphyry copper deposits, the median grade of porphyry copper deposits was % copper while the median Mo grade was % (Singer et al., ). Notable deposits include the Highland Valley Copper mine, KSM, Prosperity, and New Afton. This Google Earth compatible map shows the contained metal(s) for each deposit. Larger circles correspond to larger deposits. Clicking on a circle will bring up a table with comprehensive information about the deposit and a link to the deposit webpage in.

Porphyry copper deposits are copper orebodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself.

Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name. In later stages, circulating meteoric fluids may interact with the magmatic.

RV: Deposits of the Revett model are in thick beds of reduced (pyritic) quartzite (properly, metasandstone) near pre-ore redox fronts (Hayes and Einaudi, ; Hayes, ). Orebodies may be stacked, especially near faults (Balla, ). Copper is not associated with solid organic matter in Revett deposits, but copper may have been depositedFile Size: KB.

Porphyry ore deposits are the source of much of the copper, molybdenum, gold and silver used by humans. Porphyry ore typically forms in magmatic arcs above subduction zones.

Porphyry copper deposits account for 75% of natural copper worldwide. They are formed by magma chambers situated between 10 and 15 km beneath Earth’s surface. At this depth, the magma heats to around °C but when it comes into contact with the surrounding rock, it cools and crystallises.

Sedimentary Copper Deposits Investing News Network - May 12th, Not all metal deposits have igneous origins- sedimentary deposits can also be a valuable source of many metals, including copper. Copper is a moderately incompatible chalcophile element.

Its behavior is strongly controlled by sulfides. The speciation of sulfur is controlled by oxygen fugacity. Therefore, porphyry Cu deposits are usually oxidized (with oxygen fugacities > ΔFMQ +2) (Mungall ; Sun et al.

The problem is that while most of the magmas at convergent margins are highly oxidized, porphyry Cu Cited by: chalcosis len'tis a cataract caused by excessive intraocular copper.

search for new ore deposits. The relationships of many metallic deposits to plate boundaries has become increasingly clear, the best example perhaps being that of porphyry copper deposits.

Other plate boundary relationships range through various metallic deposits to concentrations of. Descriptions of major ore deposits world wide. Udokan is a major sediment hosted copper deposit located in Zabaykal'skiy Kray, northeast of Lake Baikal, in the Transbaikal region of eastern Russia, and ~ km NNE of Chita, the capital of the Krai.

Copper toxicity in sheep is more often a problem of nutritional management than it is excess copper intake. The purpose of this paper is to look at such factors as nutrient interactions, animal management, and environmental conditions that may increase the risk of copper toxicity and how the sheep producer can minimize these risks.

Acute poisoning may follow intakes of 20– mg of copper/kg in sheep and young calves and of – mg/kg in mature cattle. Chronic poisoning of sheep may occur with daily intakes of mg of copper/kg when grazing pastures that contain 15–20 ppm. about two-thirds of newly mined copper in the United States.

Significant quantities of by-product molybdenum, silver, gold, and platinum are also produced.

Kirkham. On a cool sunny day in May, I drove New Mexico State Road down the valley of the evocative Dry Cimarron River. For hours I saw no one, aside from ghostly travelers conjured up by “Cimarron”—dusty men on wild-eyed horses, traders with heavily-loaded mules, armed banditos lurking behind the rocks, and gaunt men of God driven by the other-worldly light in their eyes.

Porphyry Cu–(Au)–(Mo) deposits are one of the most important economic mineral associations (Sillitoe,Sillitoe,Hedenquist et al.,Heinrich et al.,Cooke et al., ), hosting most of the world’s copper resources (Ulrich et al.,Halter et al., ).More than 90% of the porphyry Cu deposits in the world are distributed along convergent margins ().Cited by: Porphyry copper deposits: Different types.

In porphyry copper deposits, copper grades can range from percent to more than one percent, while molybdenum grades can range from approximately 0. Probably the natives continued to work the deposits under the watchful eyes of Roman overseers; for the invaders were more interested in lead, the mining of which was an imperial preserve.

There were some small Roman copper mines at Llandudno, where an open-cast on Great Orme's Head yielded a coin of Aurelian (A.D. ) and many more recent. Copper is sometimes found as the free element and is present in many minerals. Important deposits are located in Canada, Chile, Germany, Italy, Peru, U.S.A., Zambia, and Zaire.

The most important copper ores are the oxides, sulphides, and carbonates. One major ore, chalcopyrite (copper pyrite), CuFeS 2 accounts for about 50% of all deposits. Porphyry copper deposit, large body of rock, typically a porphyry of granitic to dioritic composition, that has been fractured on a fine scale and through which chalcopyrite and other copper minerals are ry copper deposits commonly contain hundreds of millions of metric tons of ore that averages a fraction of 1 percent copper by weight; although they are low-grade, the.

Porphyry copper deposits are typically very-low grade with between and 1% copper. The main mineral is chalcopyrite, which is finely disseminated through the host porphyritic rocks.

The only reason these ore bodies are economic is because porphyries are huge, with hundreds of millions of tonnes available in a fairly low-cost mining setting.

Sediment-Hosted Copper Deposits (SHCD) are known to occur in Mexico with the three most recognized localities in northern part of the country: Las Vigas and Samalayuca in Chihuahua and El Jabalí, in Cuatrociénegas area, Coahuila.

Las Vigas was the first SHCD recognized in Mexico in the ´s, initially with Inferred Resources of K tonnes of. Both copper and copper-gold deposits are present near the intrusive center, with gold-silver deposits outboard from these, and lead-zinc-silver deposits present in a distal concentric zone.

The upper levels of the original underground Copper Canyon Mine, the West orebody, and the East orebody are of the central copper-gold skarn type. Porphyry copper deposits account for 75% of natural copper worldwide. They are formed by magma chambers situated between 10 and 15 km beneath the Earth's surface.

At this depth, the magma heats to. Bingham Canyon is located on the east flank of the Oquirrh Mountains, just southwest of Salt Lake City in the state of Utah, USA (#Location: 40° 31' 19"N, ° 08' 53"W).

Introduction Mineralisation was first discovered in the Bingham district in Since then it has been, at various times, a gold, silver, lead-zinc and copper producer. These are produced either by simple dipping or by galvanic methods. Dipping. Copper deposits by dipping are seldom practised except upon iron, and are generally wanting in lasting qualities, since, from the thinness of the deposit, the iron is not protected against atmospheric influences.
