Transcript of Coltan

COLTAN It deflects unwanted energy and has very good resistance to heat
It is very flexible but at the same time keeps being very strong
Has a shield against corrosive environments
its color is dark grey metallic
Coltan is a metal found in the Democratic Republic of Congo Environmental effects In the Kahuzi Biega national park the Mountain Gorilla population has been cut in half due to people killing them as bush meat because the zoo contains a large amount of Coltan(rebel armies)
After extraction of Coltan on riverbeds, miners dump the toxic waste in some other land contamination even more and can cause death of other animals and plants.
The toxic chemicals produced by extraction can sometimes flow down the riverbed and reach other villages affecting the citizens health.
Since people don't have food, gorillas and elephants are killed for their meat high in protein, they are also killed because they are in the way of getting the Coltan stored in the National Parks.(very hard to bring food from other countries)
Also, in such unique forest like the Congo forest, many rare plants have been removed to get to the Coltan or just because of toxic chemicals
Also, lot of greenhouse gases are released as well as carbon dioxide
Reduction of forests limits the amount of greenhouse gases that the forests can eliminate
After extraction of Coltan on riverbeds, miners dump the toxic waste in some other land contamination even more and can cause death of other animals and plants.
Use of Coltan Tantalum or what coltan contains is used for the production of many electronics such as phones, DVD players, even in the Sony PlayStation
It is used for most electronics because it conducts electricity so well and handles high temperatures Formation Coltan is a igneous intrusive rock
It takes a very long time to form
Forms at the very bottom of intrusions
Has to erode during many years to get to the bottom of the intrusion
It is a granite
Intrusions form when magma comes up digging a hole through the earth which can sometimes form volcanos Formation occurs here Possible countries for relocation of Coltan Congo
Western United States
Thailand My choice of relocation Colombia: This is the best place for coltan to be successful in because it is filled with igneous rocks (among the rocks coltan is formed), and there are many possible formations of intrusions Bibliography Human effects

The average Congo worker is paid 10 dollars a month
Nearly 10,000 people have moved in to work at the Kahuzi Biega National park. Most of these people depend on natural resources in the parks environment because of the lack of employment
The toxic chemicals produced by extraction can sometimes flow down the riverbed and reach other villages affecting the citizens health. Why not Thailand? Thailand is not the best option to mine Coltan because it has very little intrusions nor there are much possibilities for them to form, the only signs of igneous rocks are very little compared to the size of the country. (only the purple spots) Why not Congo? Congo will not have the best coltan future even though today on it produces the 80% of the worlds coltan. First, people have already extracted so much coltan that there are few places with a good amount of coltan. Secondly, the volcanoes that it has are either extinct or dormant meaning nothing good will come out of them and, there are not many possibilities of intrusions forming. Why not Western United States? This country does not have great future in coltan mining due to its lack of volcanoes (compared to such a big continent) and that there are very little chances of enough intrusions forming to be able to be successful.
