Abstract
This paper discusses the Ray Copper Mine in Arizona. Arizona is the largest producer of copper in USA. There are some other states where copper reserves have been discovered but Arizona by far remains the leading copper-producing state accounting for 65 percent of the total US copper-production. Copper and its by-products represent over 80 percent of Arizona's nonfuel mineral value.

Abstract
The paper relates that overall, the copper business is a risky one. The paper explains that companies must rely on the development of uses for copper around the world, and they must rely on international growth to continue being profitable. The paper explains that this is not always possible, as changes to the world economy can push down copper demand and prices for years at a time. The paper asserts that in order to compete, companies must have the ability to predict these shifts, and build flexible workplaces that are able to adapt quickly.

From the Paper
"It is difficult for countries to balance the import and export of commodities like copper. To understand why, we need to explore the history of the international trade of this mineral. The need for copper, and its use in different manufacturing applications, has been increasing for the last hundred years. Between the beginning and the end of the second World War, consumption had doubled, but it wasn't the increase in production for the war that was causing copper to be used so frequently. In fact, within another ten years after that war, consumption had doubled again in direct..."

Abstract
This small analytical research project poses the question whether an effective hedging strategy can be devised for copper futures. According to the paper, this is for a hedging strategy that accounts for price volatility in copper futures within the US market as well as the exchange rate fluctuations of the United States (US) dollar. Very few working hedging models exist to account for both price volatility and exchange rate fluctuations relative to the US dollar and copper hedging strategies for the US with respect to the US dollar.

Abstract
This paper traces the history of copper mines in Montana in an attempt to discover the true nature of the ongoing conflict. The author concludes that the violence was likely attributed to the three Copper Kings who fought amongst themselves and became infamous in trying to become the biggest and most powerful, and because of fights between labor unions against the mine owners.

From the Paper
" He then became enamored with the new statehood of Montana and began his quest to become a state senator thinking that that would give him all the power he needed. Montana became an official state, the 41st, on November 8th, 1889. He became a Helena hero by successfully lobbying to make Helena the state capital, instead of Anaconda as Daly wanted. He used his newspaper the Butte Miner as a trumpet for his election campaigns and to criticize Daly who kept growing in wealth and power himself, and had different ideas for Montana's future. Clark was the president of the Montana constitutional conventions of 1884 and 1889 but was defeated in the 1888 campaign to be territorial delegate to Congress (2, 4). Although Clark claimed election as one of Montana's first Senators, the Senate instead seated his Republican opponent (4). It was just the first of several election quests to be suspicious. In 1893 the state legislature was deadlocked and Montana was left with only one Senator, many attributed this to the ongoing conflict in the newspapers where truth became a rare commodity (1). After another deadlock in 1899, Clark was declared elected only to resign when confronted by a Senate investigation into the campaign and a pending resolution to void his election. In 1901 he was duly elected and this time served his term and retired but he went to the Senate amidst one of the worst vote-buying bribery schemes in American History (4). He and Marcus Daly had been amassing huge fortunes and feuding for control of the copper deposits and for political power for many years. In the 24 years of their violent completion they made Butte into the largest copper producer in the World (6). Clark tied the exploitation of copper to eastern capital, winning over such brilliant rivals as F. Augustus Heinze who joined forces with him against Anaconda in 1900(4). After his appointment to the Senate, Clark switched sides, dumping the loyalty of Heinze in favor of Anaconda and the copper mining interests of Montana. Clark was powerful in copper development in Arizona as well as in Montana. "

Abstract
This paper discusses how Chemical Mechanical Planarization (CMP) is one of the most effective methods in achieving adequate local and global surface planarization and how chemical mechanical polishing of copper attracts a lot of interest. It examines the effects of different factors including the slurry, polishing pads and down force etc. on the quality of planarized copper layer in CMP Cu. It also presents, a new CMP copper technique with the name of "Abrasive-free polishing (AFP)".

From the Paper
"Recent years have witnessed the rapid development of using copper (Cu) for low resistivity electrical connections in microelectronic devices.1,2 In fact, copper is one of most commonly used pure metals in the electrical industry because of its low conduct resistivity of about 6-10-8W-m and excellent mechanical properties as well. There are various methods to deposit Cu thin films, for example, electroplating, electroless plating, sputtering and thermal evaporation can be used.3.4 The copper thin films achieved by these techniques, especially those from the electrochemical techniques, are not planar enough to promise a successful multilevel interconnection. However, in fabrication of a logic device with five or more layers, at least one layer should be perfectly planar. Lack of layer planarity may lead to severe problems for photo-lithography (such as insufficient focus depth) and dry etching in sub 0.5 mm 5. Chemical Mechanical Planarization (CMP) is one of the most effective methods in achieving adequate local and global surface planarization.6 Therefore, chemical mechanical polishing of copper attracts a lot of interests in recent years."

Abstract
The paper relates that copper is one of the most in-demand minerals in trade today; as an important component in any mechanical, electrical or conductive technology, it is central to development. The paper discusses how the global copper industry has grown exponentially for the last hundred years, driven by investments in infrastructure. The paper describes the deposit mining in Chile and southern Africa, the ore extraction in Canada and Australia and the mining processes in the US, and shows how the copper industry is a global endeavor. The paper points out that ores extracted are often shipped and processed in facilities far from their original mining locations.

Abstract
This paper discusses the Montana copper mines, which, at the turn of the 20th century, were a focus of desperate conflict very unique for any place and any time. The paper describes the backgrounds of the three Copper Kings - William Clark, Maracus Daly and F. Heinze , and the battle these men waged amongst themselves for control of the mines. The day to day life of the minors, the conditions they toiled under, and the legacy that the copper wars of Montana had on the labor practices we enjoy today are also discussed.

From the Paper
"Daly and his partners bought up as many adjoining properties as they could get their hands on and then imported laborers from around the world. He especially liked the Irish or course because he was born there. What Daly didn't know at the time was that they were sitting on the largest copper sulfide deposit in the Americas (7). He built a smelter at Anaconda which was 26 miles west of Butte and connected it by rail with Butte. In 1882, he decided to mine the copper ore and increase production (3). Daly's decision to mine the pure copper or glance coincided with two major industrial advances, the dawning of the electrical age and the invention of the telephone. In 1876, at the Centennial Exposition in Philadelphia, Alexander Graham Bell introduced the telephone. Then in 1880 Edison began to really develop his ideas for transporting electricity for city lights and both new inventions needed copper wire (7). "

Abstract
The paper looks at the use of copper in history from before the bronze age, including its use as a source for currency making and its use in statues of the Roman emperors. The paper discusses the later uses of copper for ships and as a conductor of electricity.

From the Paper
"Copper is perhaps one of the most important elements for mankind, both due to its multiple uses and to its capacity to replace iron in many cases. Starting with making objects out of copper and continuing, as mankind progressed, with its use as a conductor and building material, copper was part of everyday life ever since the copper age. Even today, despite new discoveries that brought about artificially made compounds and alloys, copper remains an important element still significantly used in practice."
