Most countries mine something. China, Australia and the US are the global leaders for production value of raw materials, but extraction makes up a far larger share of the economy for some other nations. In at least 18 countries, metallic minerals and coal account for more than half of all exports; for some of these, it's more than 80%. In a no-mining-of-metals scenario, the entire economies of countries such as Suriname with its industrial gold mining, the Democratic Republic of Congo, where cobalt is king, and Mongolia, a leading exporter of copper, would be at risk.
