Metals and nonmetals

Iron ore reserves are found in most provinces, including Hainan. Gansu, Guizhou, southern Sichuan, and Guangdong provinces have rich deposits. The largest mined reserves are located north of the Yangtze River and supply neighboring iron and steel enterprises. With the exception of nickel, chromium, and cobalt, China is well supplied with ferroalloys and manganese. Reserves of tungsten are also known to be fairly large. Copper resources are moderate, and high-quality ore is present only in a few deposits. Discoveries have been reported from Ningxia. Lead and zinc are available, and bauxite resources are thought to be plentiful. China's antimony reserves are the largest in the world. Tin resources are plentiful, and there are fairly rich deposits of gold. China is the world's fifth largest producer of gold and in the early 21st century became an important producer and exporter of rare metals needed in high-technology industries.
