Answer:

Coltan is Venezuela's Oro Azul or 'blue gold'. The price of this blue gold follows an increasing demand for a high-grade metal known as tantalum, processed from refined coltan. Demand for coltan is so intense, it fetches a higher price on the international market than even gold or diamonds.

Hope it helps ☺
