Copper is one of Australia's top ten commodities, worth approximately $6 billion a year. Copper is an important metal widely used in electrical applications, plumbing and other building applications, as well as in metal alloys because of its high thermal and electrical conductivity and ability to be bent into wires.
Australia is estimated to have about 13%of the world's economic resources of copper, the second largest after Chile. Almost 75% of Australia's copper is mined near South Australia, predominantly in the giant Olympic Dam deposit.
Copper is also involved in the making industrial equipment, such as heat exchangers, pressure vessels and vats, due to its ability to conduct electricity and withstand extreme environments.
All major forms of transportation rely on copper such as the hulls of boats and ships to reduce drag and manage fuel consumption.
Cars and trucks rely on copper motors, wiring, radiators, and more; the average automobile contains two kilometres worth of copper and alloy cables, while in cars can vary from 20 kg for smaller cars,and 45 kg for luxury and hybrid vehicles. Environmental issues of
Copper mining has had a huge impact on Michigan throughout history. Copper mining has had such an impact that the Upper Peninsula of Michigan has a region referred to as “The Copper Country” because of its involvement in the copper-mining industry. The copper-mining industry has also led to technological developments necessary for hoisting and drilling as well as the development of towns and cities in the Keweenaw. In addition, it led to the creation of many potential jobs for residents of the towns that were developed to support these mines.
The objective of this experiment was to perform extraction. This is a separation and purification technique, based on different solubility of compounds in immiscible solvent mixtures. Extraction is conducted by shaking the solution with the solvent, until two layers are formed. One layer can then be separated from the other. If the separation does not happen in one try, multiple attempts may be needed.
Purpose: The purpose of the lab was to perform a series of chemical reactions in order to transform copper within different reactions in order to start and end with solid brown copper.
Stainless steel, especially, Austenitic stainless steel, because of their high corrosion resistance and customizable mechanical properties has become an indispensable part of the regularly evolving modern day technology. Stainless steels of various grades find applications in numerous fields starting from the household to the nuclear reactors; from food and beverage cans to construction of different automobile parts. The formation of impervious oxide layer on the surface makes it suitable for use in adverse environments such as sea water.
The purpose of this lab was to to cycle solid copper through a series of chemical forms and return it to its original form. A specific quantity of copper undergo many types of reactions and went through its whole cycle, then returned to its solid copper to be weighted. We observed 5 chemical reactions involving copper which are: Redox reaction (which includes all chemical reactions in which atoms have their oxidation state changed), double displacement reaction, precipitation reaction, decomposition reaction, and single displacement reaction.
Nowadays this element more active or used for infrastructures, electronics goods, and other services, this element also we call it a Dr. Copper element because of high levels of sense of Ph.D. economic benefits. Copper has 20 protons and electrons with the symbol of Cu. In 21 century the market of this element goes up to 20 million tons a year buy and sell in the world trades scale in three big cities in the world such as New York, London, and Shanghai. Cu more necessary for wire, electronics, and computer chips; Copper also helps us to away bacteria
A huge fascination of arsenic started in the 19th century when people got word of a province in southeastern Austria where people ate arsenic. Women would eat arsenic to help gain weight and fix their complexion to look more beautiful and men would eat arsenic because they believed it helped them breath easier when they were climbing high up in the mountains. One doctor by the name of Dr. Robert Craig MacLagan, was particularly interested in this and visited the town to see for himself what was really occurring. He observed the people and tested their urine to prove that they have been indeed ingesting arsenic. He wrote about the things he witnessed in the Edinburgh Medical Journal. The men in the town would eat 6 grains/dose at least twice a week, sometimes eating it on their bread or just drinking it with their water. As a result many Victorians began self-medicating themselves with arsenic.
Review the effects of arsenic as a soil pollutant on human health. You need to consider the major sources of arsenic (both natural & man-made), pathways for uptake by people and the impacts on human health.
In the book Copper Sun by Sharon Draper the female heroin, Amari struggles with the worst hardships she's ever faced. After the light skin men attacked her village in Africa she was taken captive and brought to America where she was bought by a wealthy landowner as a birthday gift for his son. She was put through many hardships and was treated horribly. Although Amari was forced to work on a rice farm in the kitchen and cleaning during the day, and in her master’s bedroom at night. Amari eventually found freedom from her owner the racism against her never ended. Racism against African Americans and people of other races is still very much prevalent. The way that racism is expressed has changed drastically over the years. Despite the fact that
The Electrolysis of Copper Sulphate Aim Analyse and evaluate the quantity of Copper (Cu) metal deposited during the electrolysis of Copper Sulphate solution (CuSo4) using Copper electrodes, when certain variables were changed. Results Voltage across Concentration of solution electrode 0.5M 1.0M 2.0M 2 5.0 10.6 19.5 4 10.5 19.8 40.3 6 14.3 26.0 60.2 8 15.2 40.4 80.3 10 15.0 40.2 99.6 12 15.1 40.0 117.0 Analysing/Conclusion The input variables in this experiment are; concentration of the solution and the voltage across the electrodes. The outcome is the amount of copper gained (measured in grams) at the electrodes. By analyzing the graph, we can see the rapid increase of weight gained for the 2.0 molar concentration as the gradient is steeper.
Stainless steel is a type of alloy that has a very strong lattice structure (an arrangement/ shape of the crystals or other objects) which in some case can be more beneficial than others depending on the type of application it may be used for. In many cases this structure will make the material more suited to being used in engineering applications such as tools for instance a hammer (stainless steel alloys) , also they can be used for gears, engines, electrical motors and hydraulic systems because the structure makes the material so strong. So when the arrangement of the structure is as above it makes the overall material even stronger which makes it a good for all the applications stated above. I believe its strength and durability are its main properties as these are commonly needed in the engineering industry, although it is also very well known to be used for its corrosion resistance as it is resistant to many types of corrosion. It is used for these properties because the components such as gears need to be strong in order to keep transferring and altering the rotary motion and torque exhibited in the machine that it may be used in, durable to withstand any loads or pressure put onto it and also corrosion resistance to give the components a bigger life span and increase its rate of work throughout its required use.
Though it has had many negative impacts on the environment in the past, mining is a vital industry completely necessary to our economy and lives. Nearly every item we use or encounter in our day to day lives is mined or contains mined products. Without the excavation of such materials things like computers, televisions, large building structures, electricity, and cars would not be possible. Virtually every technological and medical advance uses minded materials, without which millions would suffer. Some examples of minerals in the home include the telephone which is made from as many as 42 different minerals, including aluminum, beryllium, coal, copper, gold, iron, silver, and talc. A television requires over 35 different minerals, and more than 30 minerals are needed to make a single personal computer. Without boron, copper, gold and quartz, your digital alarm clock would not work. Every American uses an average 47,000 pounds of newly mined materials each year, which is higher than all other countries with the exception of Japan, which is a staggering figure representative of our dependence and need for mined minerals. Coal makes up more than half of nation’s electricity, and will continue to be the largest electrical supplier into 2020 & accounting for some 95 percent of the nation's fossil energy reserves – nine of every ten short-tons of coal mined in the United States is used for electricity generation. As the population of the world grows more mineral resources must be exploited through mining in order to support the rising demand for such products. Though it may present a hazard to the environment and those physically located nears the mines, the materials extracted from mines...
‘’The Australian association demand that Australian has enough saves to be to uranium what Saudi Arabia is to oil. ’’ The examination proved wrong in 2011 while it figures that Saudi oil produces 466 times more income than Australian uranium. Export revenue could quadruple and uranium would fall outside of the top 20 list of exporting product comparing with number 1 and 2 iron ore and concentrates 62.7% and coal 47.9% whereas uranium is only 0.6%. Uranium every annum income would add up to around $10 billion and thus would fall short of Iron ore revenue by a factor of 6.5%.
Metals possess many unique fundamental properties that make them an ideal material for use in a diverse range of applications. Many common place things know today are made from metals; bridges, utensils, vehicles of all modes of transport, contain some form of metal or metallic compound. Properties such as high tensile strength, high fracture toughness, malleability and availability are just some of the many advantages associated with metals. Metals, accompanied by their many compounds and alloys, similar properties, high and low corrosion levels, and affects, whether negative or positive, are a grand force to be reckoned with.
It is clear that the US consumption of polluting substances like lead, platinum and rubber has dropped due to improvements in the environmental friendliness of auto manufacturing, since these materials have been in use for cars since the 1950s. By replacing materials with those of a lower density has also made an important impact on fuel economy. Studies show that making 10% reduction in mass yields 5% improvement in fuel economy. Indeed, the US automakers in the last 25 years have responded to the government regulations Corporate Average Fuel Economy by changing materials to lighter ones like aluminum and plastics. Newer developments using other components like Magnesium, polymer composites, and ceramics also are helping to make further improvements to fuel
