Ore mining in the Yangtze River

1. The Yangtze River Basin is an important mineral resource area in China. Ferrous metals, non-ferrous metals, precious metals, non-metallic and energy minerals are rich in reserves, some of which are the highest in China and even in the world. Yunnan, Guizhou, Sichuan, Hubei, Hunan, Anhui and other provinces in the basin are all major provinces of mineral resources in China. Mineral resources and related instries have become important pillar instries in these regions

the Yangtze River Basin is the main base of ferrous metals (iron, manganese, chromium, titanium, etc.) in China. Xichang and Panhua areas located in the upper reaches of the Yangtze River are the main mineral bases of vanadium, titanium and magnetite in China
Daye of Hubei Province in the middle and lower reaches of the Yangtze River, Nanjing, Ma'anshan and Wuhu of Jiangsu and Anhui provinces are also important magnetite mineral bases in China. Magnetite is also well developed in Kunming and Wuding of central Yunnan. These areas have become the main ore sources of large and medium-sized iron and steel instrial bases (such as Pangang, WISCO, Masteel, Kunming Iron and steel, etc.). In addition, sedimentary hematite in central Hunan, western Jiangxi and Western Hubei, siderite in Shaanxi Qinling and hematite in Gansu Qinling also have important instrial value. The Yangtze River Basin is also the main procing area of manganese resources in China. Especially in the Sinian, Devonian and Permian strata of Hunan, Hubei, Sichuan, Guizhou, Yunnan and Guangxi provinces, sedimentary manganese ore and manganese oxide ore formed after weathering are the main ore sources of China's metallurgical instry

nonferrous metal minerals in the Yangtze River Basin are relatively concentrated, with huge reserves, especially antimony, tungsten and other minerals. The mineral reserves account for more than 50% of the country, mainly distributed in Hunan, Guangxi, Jiangxi, Guizhou, Yunnan and other places. Among them, tungsten deposits account for 30% and 22% of the total reserves in Hunan and Jiangxi provinces respectively; Tin deposits account for 31%, 27% and 10% respectively in Guangxi, Yunnan and Hunan; Antimony deposits account for 28%, 26% and 17% respectively in Hunan, Guangxi and Guizhou provinces. The above minerals are the perennial export mineral procts of China. In particular, the antimony mine is the most in the world, and Hunan tin mine is known as the "antimony capital of the world". Copper, bauxite, lead-zinc and mercury mines are also in the forefront of the country. The famous Dongchuan Copper Mine in Yunnan, Tonglushan Copper Mine in Daye, Hubei, Dexing Copper Mine in Jiangxi and Tongguanshan Copper Mine in Anhui are the main mineral bases of China's nonferrous metal instry. Bauxite resources are also very rich, its reserves account for about 1 / 3 of the country, mainly concentrated in Guizhou. The lead-zinc deposits are mainly concentrated in the hinterland of Qinling Mountains in the south of Shaanxi and Gansu, and in Hunan, Sichuan and Yunnan. Mercury deposits are mainly concentrated in Guizhou, southern Shaanxi, Sichuan, Hunan and other places, accounting for more than 80% of the country's reserves, and Guizhou alone accounts for about 41%
gold deposits are mainly distributed in the southern Qinling Mountains, Shaanxi Gansu Sichuan golden triangle, Hubei, Hunan, Anhui, Jiangxi and other places. Silver deposits are mainly concentrated in Jiangxi, Hubei and southern Shaanxi

the Yangtze River Basin is also a relatively concentrated area of non-metallic mineral resources in China. China's gypsum mineral reserves rank first in the world, with three gypsum proction bases in the Yangtze River Basin (Yingcheng, Hubei, Nanjing, Jiangsu and Shaodong, Hunan). China's phosphate resources are also in the forefront of the world, and the reserves are mainly concentrated in Hubei, Yunnan, Guizhou, Hunan and Sichuan provinces in the Yangtze River Basin. China's six major phosphate proction bases are located in the Yangtze River Basin (Kaiyang, Guizhou, Kunming, Yunnan, Jingxiang, Hubei, Jinhe, Sichuan, Liuyang, Hunan, Jinping, Jiangsu). China is the world's largest procer and exporter of barite with large reserves and high quality. This kind of mineral resources are mainly concentrated in Guizhou, Hunan, southern Shaanxi and southern Gansu in the Yangtze River Basin, of which Guizhou alone accounts for about 1 / 3 of the total reserves in China. Gongxi, Xinhuang, Hunan and Tianzhu, Guizhou are famous barite mines in China. In addition, sulfur, fireclay and fluorite in the Yangtze River basin also play an important role in China. The high alumina refractory clay in Guiyang is one of the important refractory clay mineral bases in China. Taolin, Hunan Province is an important proction base and export base of fluorite in China. The limestone in the Yangtze River Basin is very well developed and has become the largest cement limestone mineral base in China. China's cement instry has been ranked first in the world for many years. At least half of the cement limestone mining bases are concentrated in the Yangtze River Basin. The Yangtze River Basin is also an important mineral base of granite, marble, glass and siliceous raw materials, diamond and gemstone in China< The limited coal resources are mainly concentrated in Guizhou, Hunan, Hubei, Jiangxi, Sichuan and other places, and their distribution horizons are concentrated in the lower Carboniferous (such as Lianyuan and Shaoyang in Hunan), Permian (such as Chongqing Panxian in Guizhou, Leping Fengcheng in Jiangxi, Leiyang Chenzhou in Hunan, and Eastern Hubei Southern Anhui) In the upper Triassic (such as Pingxiang, Jiangxi Province). The oil and gas resources in the Yangtze River Basin are mainly concentrated in Sichuan Basin, Nanyang Basin and Jianghan Basin. The gas fields in Central Sichuan, East Sichuan, Northwest Sichuan, Southeast Sichuan and southwest Sichuan, Henan Oilfield and Jianghan Oilfield are exploited. In addition to the main energy minerals mentioned above, uranium deposits in the Yangtze River Basin, stone coal in the middle and lower reaches of the Yangtze River, and peat in Zoige area in Northwest Sichuan are also important energy minerals.

It's mineral resources

according to the detailed rules for the implementation of the mineral resources law of the people's Republic of China, river sand is natural quartz sand, which is a non-metallic mineral in the classification of mineral resources

mineral resources, also known as mineral resources, refer to the mineral or useful element aggregates formed by geological mineralization, which are naturally stored in the crust or the surface, buried in the ground or exposed on the surface, in solid, liquid or gaseous state, and have development and utilization value

protection methods of mineral resources:

1. Rational development and utilization of mineral resources, optimize resource allocation, and realize the optimal depletion of mineral resources

To prevent the loss, waste or damage of mineral resources, unreasonable indiscriminate mining should be restricted or prohibited

3. Control the whole process of the development and utilization of mineral resources to minimize the environmental cost

The ecological environment of mining area should be protected to prevent the mine from becoming barren and barren at the end of its life

extended data

classification of mineral resources

according to different classification standards, there are a variety of classification methods:

first, according to the different fields of mineral resources generation and occurrence, it can be divided into land resources, marine resources and alien resources

Second, according to the different uses of mineral resources, it can be divided into 10 categories (classification used in China's mineral resources statistics):

1. Energy minerals: coal, oil, oil shale, natural gas, uranium, etc

(2) ferrous metal minerals: iron, manganese, chromium, etc

Non ferrous metal minerals: copper, zinc, aluminum, lead, nickel, tungsten, bismuth, molybdenum, etc

the Yangtze River originates from the "roof of the world" - the southwest side of Geladandong peak in Tanggula mountains of Qinghai Tibet Plateau. The main stream flows through 11 provinces, autonomous regions and municipalities directly under the central government of Qinghai, Tibet, Sichuan, Yunnan, Chongqing, Hubei, Hunan, Jiangxi, Anhui, Jiangsu and Shanghai, and flows into the East China Sea to the east of Chongming Island. The total length of the main stream is about 6300 ㎞, more than 800 kilometers longer than the Yellow River (5464 ㎞), ranking third in the world after the Nile in Africa and the Amazon in South America. However, the Nile River Basin crosses nine countries in Africa, the Amazon River Basin crosses seven countries in South America, and the Yangtze River is unique to China

the main stream of the Yangtze River runs through central China from west to East. Hundreds of tributaries radiate from north to South and extend to parts of eight provinces and autonomous regions, including Guizhou, Gansu, Shaanxi, Henan, Guangxi, Guangdong, Zhejiang and Fujian. The basin covers an area of 1.8 million square kilometers, accounting for about 20% of China's total land area. Most of the water of the Huaihe River also flows into the Yangtze River through the Grand Canal

the upper reaches of the main stream of the Yangtze River are above Yichang, with a length of 4504km and a drainage area of 1 million square kilometers, of which Zhimen reaches Yibin, known as Jinsha River, with a length of 3464km. The section from Yibin to Yichang, commonly known as Chuanjiang River, is 1040 km long. Yichang Hukou is the middle reaches, 955km long, with a drainage area of 680000km2. The lake mouth to the sea mouth is the downstream, 938 km long, with a drainage area of 120000 square kilometers[ 1]

Jiangxi Dageng, Hunan Shizhuyuan tungsten mine, Jiangxi Dexing Copper Mine, Hunan Lengshuijiang antimony mine, Hunan Shuikoushan lead zinc mine are all famous non-ferrous metal procing areas in China, which provide favorable conditions for the development of non-ferrous metal smelting

10. The middle and lower reaches of the Yangtze River are from Yichang, Hubei Province to the estuary, including Hubei, Hunan, Anhui, Jiangxi, Jiangsu, Zhejiang and Shanghai, which are six provinces and one city in East China. Metals are divided into ferrous metals and non-ferrous metals. Ferrous metals only refer to iron, chromium and manganese. In addition, all of them belong to non-ferrous metals. The middle and lower reaches of the Yangtze River are dominated by non-ferrous metals, among which Hunan ranks first and Jiangxi ranks second (also the top two in China) Hubei has Daye Iron Mine Xiangyang Phosphate Mine Hunan has tin mine antimony Xiangtan Manganese Mine Yuanling Phosphate Mine Anhui has Tongling's Linchuan copper mine Huaibei Coal Mine Maanshan Iron Mine Jiangxi has Dexing Copper Mine Dayu tungsten mine Pingxiang coal mine Shuikoushan lead zinc mine Jiangsu has Xuzhou Coal Mine Meishan Iron Mine Zhejiang and Shanghai are not so good it's not worth saying that resources are tight or not, it depends on the economic development of a region As we all know, the Yangtze River Delta is the economic center of our country, and our country is the "world factory". The second instry is the most developed. Moreover, the economic development speed of our country ranks first in the world. Even if non-ferrous metals are rich, it can not meet the needs of economic development
