What's "mangano"?

Miners call unrefined sand "mangano", but they do not know what it is used for and what can be obtained from it.

The hills of Rubaya are full of manganese and coltan. Coltan is an invaluable mineral for the world's technological industry.
In the past, Bosco Ntaganda, former leader of the M23 rebels, exploited the hills around Rubaya. Minerals in Congo's subsoil are believed to be the cause of the endless war in this region.
