Copper is a valuable resource whose intricate steps from initially a raw product to ultimately the final product may be traced. The life of copper can be followed from its extraction, processing, and disposal. All of these steps, including the wastes produced, have an impact on human life and the environment. The developments of resources, such as copper, have helped change history. The environmental impacts of these changes may also be felt. Thus, it is important to understand the in’s and out’s of the process. By doing this, it is possible to see what resources and what waste products come out of this resource. Only then, can proper methods be taken to manage this resource properly.
Copper is an important mineral resource used in many different areas. Its properties of high ductility, malleability, and thermal and electrical conductivity, as well as its resistance to corrosion, make copper very useful as a major industrial metal (http://minerals.usgs.gov/minerals/pubs/commodity/copper). Copper can be refined from metal ores or scrap copper so it can be used as a powder in automotive, aerospace, electrical equipment, in –fouling compounds, and various chemicals and medical processes. Compounds of copper can be found in fungicides, wood preservatives, copper plating, pigments, electronic applications, and specialized chemicals. It can be produced either as a primary product or as a co-product of gold, lead, zinc, or silver (http://nuclear.hazard.uiuc.edu/packets/primmetals/chapter5.htm).
Following after steel and aluminum, copper is ranked third in world metal consumption. In 1990, the major copper-consuming nations we...

- Chile’s economy Overview: Chile’s economy is based on the export of minerals, which is worth about half of the total export of the country. The most valuable resource is copper, and the country is considered the world’s largest producer. Agriculture provides jobs for about 15% of the population; it accounts for about 6% of the national wealth, but produces less than half of the domestic needs. The country’s primary agricultural area is The Vale of Chile; its vineyards are the basis of Chile’s wine industry.... [tags: copper, petroleum]

- Platinum as an Invaluable Earth Resource The advent of the Industrial Revolution sparked worldwide large-scale use of minerals in the mid 18th and early 19th centuries, as well as continued growth during the next several hundred years. Over a period of 150 years from 1750-1900, global mineral use saw an increase of roughly 1000 percent while the world population merely doubled. Since 1900, mineral production has increased roughly 1300 percent (Young 6), and the world has become completely dependent upon the various uses of limited mineral resources.... [tags: Papers]

- Threats to Groundwater The 1/3rd of the world is covered with land. Other sector is in water. Water is one of the most important natural resources for living. It is use for drinking, fertilizing, washing and many other things to do with it. Now the water condition is very bad. The environment suffers the water condition and its purity. The ground water is one of our valuable sources. “The water we drink and use everyday might be called our most valuable resource. Agriculture, manufacturing, brewing, and other day-to-day activities depend on reliable, pure groundwater.... [tags: Soil, Precipitation, Resource]

- Human resource is the most valuable and unique asset of an organization. The successful management of an organization’s human resource is an exciting, dynamic and challenging task , especially at a time when the world has become a global village and economies are in a state of flux. The lack of talented resource and the growing expectation of the modern day employee has further increased the difficulty of the human resource function. Human Resource Management (HRM) can be defined as “the set of programs, functions, and activities designed and performed in order to capitalize on both employee as well as organizational effectiveness....

The transmitting antennas and the receiving antennas are linked such that the quality (the bit error rate (BER), or the data rate) for each user is improved. The viability of implementing MIMO system and the associated signal processing algorithms increases with an equal and corresponding increase in the computational power of the integrated circuits. Figure 3.1 represents a MIMO wireless communication system: The above block diagram illustrates the following discrete time signals: transmitted symbol vector x € XM, channel matrix H € RNXM, additive noise vector n € RN, received vector y € RN, and detected symbol vector x ̂...

Ultraviolet-Visible Spectroscopy Spectroscopy involves the measurement of light absorbed or emitted from a sample. In ultraviolet-visible spectroscopy (UV-Vis), light in the ultraviolet-visible region has the same energy as energy levels for some of the electrons in molecules, so absorption of this radiation will excite electrons in a molecule to higher energy orbitals....

- Introduction International law is a valuable resource for the New Zealand courts. Courts can draw on the expert minds of other judges. Consistency with international law, especially concerning human rights, gives citizens security. Conversely, judges must always prioritise local circumstances. In some situations, deviating from the law established overseas may bring the most justice. The value of international judgements International law is a wealth of expertise and history. The common law in New Zealand is slow to develop due to the limited number of cases that the Supreme Court can hear.... [tags: Law, United Nations, Human rights, Common law]

- Purpose The purpose of this experiment is to use our knowledge from previous experiments to separate a copper compound and from there make calculations relevant to the experiment. The calculations that we had to make in this experiment had to do with finding the percentage of copper in copper compound and from there find the formula weight of the copper compound. Question or Problem The question that was proposed by the instructor for investigation was: Can the % composition of an element in a compound be determined accurately (Lab Manual 61)....

- Support: The most predicted forecasts for climate change are all associated changes in the world’s most valuable resource-water. Although the exact extent of climate change is unknown it is undeniable that the global climate is already shifting. Global modifications will include a rising sea level which will engulf the coasts of many of the world’s cities, which is rising at the current rate of about 3.1 cm per year ; more intense and frequent storm surges, which make an already crumbling infrastructure even more at risk for failure and the likelihood of water pollution and/ or sea water infiltration into existing aquifers more evident; and increased drought throughout the world which affe...
