Transcript of Tantalum
By: Ayesha and Kainat
Mining and Processing
Open pit mines
Blasting, crushing, and transporting ore to free tantalum
Ore is concentrated through gravity, electrostatic and electromagnetic processes
Concentrate mixed with hydrofluoric and sulphuric acids at high temperature
Tantalum and niobium dissolve as fluorides
Concentrate broken down into slurry
Slurry=filtered-> tantalum oxide
Tantalum oxide + molten sodium= tantalum metal
Value consumed in 2014- exceed $250 million
Consumption decreased 53% of that in 2013
No tantalum mines in US since 1959
Strong, ductile, grayish silver, heavy, and very hard metal.
Nearly immune to chemical attacks at room temperature
Attacked by hydrofluoric acid, acidic solutions containing the fluoride ion, and free sulfur trioxide.
High melting point
Make components for chemical plants nuclear power plants, airplanes and missiles
Make surgical equipment such as implants (joints and cranial plates)
Used in electronic industries to make capacitors and high power resisters
Also Cars, bridges
" Because of Africa's world war"
"Here let me tell you the story....."
"What? How come? What happened there?"
"Why is tantalum a conflict mineral?"
Rebellion started between Kabila and Rwanda.
The Rebellion ends.
Rebel groups continue to remain active in the four eastern provinces:
New start off of first free elections in the country. Joseph Kabila becomes president but was unsuccessful to carry out international expectations of peace.
The Congo split into different city states, collapsing communication systems and weakening the official justice system.
Rwanda’s post-genocide Tutsi government attacked the DRC in search of Hutu militia who had fled there. Rwanda backed Congolese rebels, threw out Mobutu from office and replaced him with Laurent Kabila.
Dominican Republic of Congo
Andrew Ekeberg was the first to discover Tantalum in Sweden in 1802. He named it after the son of Jupiter, Tantalus.
"What an interesting story!"
We disagree with Congo
Uganda and Burundi
are with us
We would disagree with Rwanda and Uganda!
We have many other countries who support/agree with us
All in alliance with Congo
Marched into Congo and invaded
"Here let me show you through visuals..."
"Yes, Dr Dumble this is all true."
"Tantalum also causes a lot of strife."
DRC= abundant in tantalum = global demand for it.
Trading of these minerals can promote war
Neighboring countries can be greedy and try to control the mines in DRC using physical violence.
"All belligerents in the war were benefiting in one way or another, with the Congolese people the only losers, and now the conflict was mainly about access, control and trade of coltan, diamond, copper, cobalt and gold.”
~ Panel of Experts on the Illegal Exploitation of Natural Resources and Other Forms of Wealth of the Democratic Republic of Congo
Tantalum and other conflict minerals such as tin, tungsten, and gold = valuable to the DRC.
Resources help the economy within the country and outside the country.
Resources are used in every aspect in daily life such as giving people a better lifestyle, increase in jobs, better education, improvement in healthcare system, and trade.
Abundance of resources increases the country's international value and international trade.
