Where's the biggest iron mine in China?
With the neutral sodium or partial sodic volcano intrusive iron ore related activities, such as Jiangsu, Anhui two provinces of Ningwu ore, Yunnan Dahongshan Iron Mine; sedimentary hematite and siderite deposit in Western Hubei Province, such as the west, eastern regions of hematite; metamorphic sedimentary iron ore, iron ore, iron ore, such as Anshan Jidong; weathering eluvial ore, such as Guangdong Baoshan, Guizhou Kuanyinshan etc. The genetic types of iron ore are the most important in metamorphic sedimentary magnetite deposits distributed in Northeast China and North china. The type of iron content is low (about 35%), but large reserves, accounting for about half of the total reserves, and optional good performance, after dressing containing 65% iron mineral resources in Liaoning province can be rich, reserves of the country's first iron ore, located in Anshan, Benxi area, reserves of concentrate more than about 10000000000 tons. From the metallogenic epoch, the formation of iron ore were from Proterozoic to Cenozoic, but in Proterozoic important force.
In terms of provinces and autonomous regions, Liaoning ranks first in proven reserves, followed by Hebei, Sichuan, Shanxi, Anhui, Yunnan and Inner Mongolia. China in iron ore, rich iron ore less ore reserves accounted for 2.53% of the total reserves, found only in Hainan and Hubei and other places of Daye city. From the point of view of iron ore genesis, according to Cheng Yuqi and Zhao Yiming's opinion, the main iron and basic ultrabasic magmatic intrusive magmatic deposit related activities, such as Sichuan Panzhihua iron ore deposit, and the acidic (including partial mafic and alkaline) magmatic metasomatic hydrothermal activities related to iron ore deposits such as Hubei, Daye, Fujian, Inner Mongolia Huanggang, Ma keng;
China is a country with abundant total iron ore resources and low iron content. At present, the proven reserves of 1834 mining areas, total reserves of 463 tons of ore, ranking fifth in the world. In addition to Shanghai and Hongkong Special Administrative Region, iron ore is distributed all over the country, with the most abundant resources in Northeast and North China, followed by Southwest and Central South china.
