We see the materials gold, tin, tungsten and tantalum in our every day life. Each of our devices contains at least on of these raw materials, be it gold in the bonding wires, tantalum in the capacitor, tungsten in a traveling wave tube amplifier or tin in a soldered point.

There the profit out of the export of the raw materials does not lead to a wealthy economy but finances the lasting for years civil war.
