What minerals are there in Yunnan?

The mineral resources in Yunnan mainly include: lead, zinc, germanium, indium, thallium, cadmium, phosphorus, crocidolite, tin, platinum, silver, potassium salt, arsenic, wollastonite, sandstone for cement, diatomite, copper, nickel, cobalt, antimony, serpentine for fertilizer, salt mine and so on. Mineral resources in Yunnan Province are distributed in Gejiu, Wenshan and Baoshan. The proven reserves of Dahongshan copper mine and antimony mine in Xinping are 6,543,8+556,400 tons, mainly distributed in southeastern Yunnan and western Yunnan. Resource prospect: 2,065,438+/kloc-0,000 tons of tungsten ore: mainly distributed in southern Yunnan and western Yunnan. Except Malipo and Zhongdian tungsten mines have been mined, most of them are associated minerals with low grade, and it is difficult to utilize nickel ore, which is mainly distributed in southern Yunnan. Because 76% of the reserves are nickel silicate, the metallurgical technology of mineral processing is not up to standard, and bauxite is difficult to be used for the time being: iron ore is mainly distributed in Kunming and Wenshan areas; Manganese ore is mainly distributed in central Yunnan and near Kungang. Titanium placers are mainly distributed in southeastern Yunnan and western Yunnan. Extra-large titanium placers are mainly distributed in Kunming and Baoshan areas, and found in Wuding, Luquan and Fumin areas near Kunming, with high grade, easy mining and large geological reserves. At present, it is one of the regions with the best resource prospects in China: gold mines are mainly distributed in western Yunnan and southern Yunnan, and three major gold mines such as Mojiang, Liu Zhen and Yuanyang have been proved; platinum group metal minerals are mainly distributed in southern Yunnan and northeastern Yunnan; platinum group metal minerals mainly include platinum, palladium, osmium, iridium, ruthenium and rhodium, which are rare, rare earth and rhodium in central and western Yunnan. The metal reserves are 4,743 tons of indium, 7,776 tons of thallium and 79,500 tons of cadmium 1, all of which are in China. Germanium 1 1 12.78 tons, ranking second in the country; Beryllium (ore quantity) is 36,400 tons, zirconium (ore quantity)194,600 tons, and strontium (celestite) is 3,573,654.38+000 tons, ranking fourth in the country. Ore types, except strontium as a single deposit, phosphate ore, monazite and zircon as placer, are all associated or biogenic components in non-ferrous metals. At present, most of them have not been developed and utilized: they are mainly distributed in eastern Yunnan, southern Yunnan and northeastern Yunnan, with a resource prospect of 70 billion tons. The proven reserves of anthracite in Fuyuan Laochang mining area are nearly 4 billion tons, and the proven reserves of lignite in Zhaotong Basin are 810.50 billion tons, which is the largest anthracite and lignite phosphate base in southwest China at present. Mainly distributed in central Yunnan, salt mines around Dianchi Lake near Kunming: Anning large-scale salt mine near Kunming, with large thickness and high grade, is suitable for large-scale water mining. Within the scope of 60 square kilometers, the prospective reserves of sodium chloride and mirabilite have been controlled to be 65.438+03.089 billion tons and 6.248 billion tons, respectively, which are ideal potash mines in salt chemical industry base: Mengyejing potash mine in Jiangcheng, nepheline syenite mine in Baiyun Mountain in Gejiu, containing potassium chloride, sulfur and iron, mainly distributed in the east and northeast of Yunnan. Yunnan has a complex geological structure and is rich in metallic and nonmetallic minerals. Non-metallic minerals are most widely distributed in coal, among which Carboniferous and Permian are the most important in Paleozoic coalfields. Mesozoic coalfields are mainly produced in Triassic; Cenozoic coalfields are produced in tertiary strata, mainly lignite. Phosphate rocks were formed in Meishucun Formation of Early Cambrian. Non-metallic minerals such as rock salt, potassium salt and gypsum were formed in Mesozoic. Metal mines are mainly non-ferrous metal mines, with many kinds and large reserves, especially tin mines, copper mines and titanium mines, which rank first in the country and are known as the "Kingdom of Non-ferrous Metals". Iron ore was formed in early metamorphic rocks, and shallow-sea sedimentary iron ore was formed in Devonian sandstone. Metallurgical industry is mainly engaged in the mining and smelting of non-ferrous metals, and it is an important non-ferrous metal production base in China. Among them, tin mines are world-famous, with the national output ranking 1, enjoying the reputation of "tin capital"; Dongchuan, Yimen and Yongsheng are the main copper-producing areas. The copper produced in Dongchuan Copper Mine is silvery white, which is called "Yunnan Copper". Lanping lead-zinc mine has large and concentrated reserves, high grade, easy mining and large smelting scale. In the iron and steel industry, the output of steel, pig iron and steel increased the fastest. Among them, high-quality small profiles are basically self-sufficient. Kunming Iron and Steel Plant near Anning has developed into a medium-sized iron and steel complex integrating mining, ironmaking, steelmaking and steel rolling.
