Copper Mines In Zambia By: Alex Elizalde
What is Copper? • Copper is a chemical element with the symbol of Cu on the periodic table. • Very ductile and high thermal and electrical conductivity. • Pure copper is soft and is in a pink or peach color. • A transitional metal Google Imigies
How is mined? • Most copper ore is mined or extracted as copper from open pit mines. • deposits that contain 0.4 to 1.0 percent copper. • Copper has been in use at least 10,000 years, but more than 95 percent of all copper ever mined and smelted has been extracted since 1900. • Chile, Peru, Zaire, and Zambia are the biggest producers of copper. wearepower.wordpress.com
How is it taken from the ground? • The most common form of copper ore is chalcopyrite. • Electro refining, Smelting, and Roasting are some methods of taking the copper out of chalcopyrite. • There are a lot of other forms of copper but they aren't as good as chalcopyrite. odyssei.com
Zambia copper • Zambia has one of the best copper belts in the world and now is being overused. • The companies are polluting local rivers and wildlife. • These are also harming the works because of the fumes. kapitro.sarawak.gov.my
working conditions • The working conditions in Zambia are getting worse and worse. • The hours are getting longer and people are dying from the toxic fumes of pure copper and other chemicals used in the making it. • Now the wife's of the miners are protesting against the bad working conditions dhtsv.com
Pollutions in water • The chemicals from the mines are being leaked into the people river water which used to be clean and fresh and now are dirty and undrinkable. • People are getting burns from the acidic chemicals that are being used in the mines. wearepower.wordpress.com
Pollution to plants • The water that is leaking out of the mines and refineries are soaking into the ground and making plants die, • Areas that used to be fertile now are unusable because of the bad soil that wont go away for centuries. http://images.google.com/imgres?imgurl=http://swroc.cfans.umn.edu/S
Pollution to wildlife • Animals are also no exception to the dangers of the copper. • Copper has made a lot of the animals there migrate to a place where they can actually live without being poised. • About 15% of the native animals have left and more will keep leaving if they don’t stop. http://feww.files.wordpress.com/2007/10/water-pollution.JPG
