China is the world's largest consumer of coal and has the largest coal industry. It holds about 13% of the world's reserves, but has one of the worst records in terms of human safety, as thousands die annually.

 The process of smelting copper ore was most likely discovered in China around 2800 BC. China is the largest consumer of copper in the world and second largest producer. Copper ore is scarce in China; most of the ore that the Chinese smelt is imported.
