Coltan is mined through a fairly primitive process. Miners work together digging large craters in streambeds, scraping away soil from the surface to get to the coltan underground. The indiscriminate exploitation of coltan is dramatically affecting environmental biodiversity and disrupting ecosystems around mining sites.
As a result, the coltan mining industry, and the prized metal tantalum extracted from it, is a "conflict mineral", closely linked to a range of human rights abuses in a similar way that Africa's ...

Making it a crucial component of an electronic ...
Coltan mining is a relatively crude process, like the California gold rush of the mid-1800s. Teams of workers dig large pits in streams and riverbeds and dig though the surface dirt and mud to reach the coltan hidden deeper underground. Then a water and mud mixture is placed in large tubs, where the heavier coltan settles to the bottom.
