[Congo] Coltan???

Coltan, perhaps these words sound unfamiliar for the first time to hear it. Coltan is black mineral, which is very valuable, which combines niobite and tantalite. This mineral is used in a variety of technological equipment, including mobile phones, computer chips, weapons, etc.

Africa, especially countries of Congo, a country producing 80% of the world's coltan. Democratic Republic of Congo (formerly Zaire between 1971 and 1997), is a country in Central Africa. It shares borders with Central African Republic and Sudan to the north, Uganda, Rwanda, Burundi, and Tanzania in the east, Zambia and Angola in the south, and the Republic of Congo in the West.

Coltan price in world market could reach three times the price of gold, and this triggered a bloody war in this country. And who better to make sad, life coltan miners are still poor, not able to get a decent livelihood from such hard work. And their lives were often exploited and many of them have accidents in the mining process without adequate compensation. It's sad, in addition to technological developments which require us to continue to grow rapidly, it must be coupled with the sacrifice of our brothers in other parts of the world.
