Current Status of Mineral Resources Development in Weinan

Mining plays an important role in the economic development of Weinan. However, the current mining situation in Weinan has problems such as high level of development of mineral resources, low development technology, and low utilization level. The resource advantage has not been transformed into economic advantage. Resource shortage is one of the key factors restricting the development of the national economy. To this end, the state proposes industrial restructuring, takes a new road to industrialization, and promotes the optimization and upgrading of industrial structure. Under the circular economy model, the industrial structure optimization is intrinsically linked with the circular economy. On the one hand, the circular economy promotes the adjustment of industrial structure; on the other hand, industrial restructuring is an important means of developing circular economy, and is the driving force for the sustainable development of the national economy. Source. It is of great significance to choose the research on mining structure optimization under the circular economy and realize the sustainable support of resources for social and economic construction.

   I. Overview of Minnan Mineral Resources

The southern part of Jiangxi is located in the eastern section of Nanling, bordering Wuyi in the east and Zhuguang in the west. It has unique geological structure and favorable metallogenic conditions, and it is rich in mineral resources, especially tungsten, tin , rare earth, fluorite and other minerals. The resources are unique and extremely rich. They are in good condition and high in quality. They enjoy the reputation of “World Tungsten Capital” and “Rare Earth Kingdom”. Weinan has a long history of mineral development and plays an important role in the national economy. It has become a pillar industry in southern Fujian. At present, 106 minerals have been discovered, of which 75 species have proven reserves; 1254 mineral deposits, including 28 large deposits, 60 medium-sized deposits, 712 small deposits, and 454 mines. Among the minerals with proven mineral resources reserves, 10 are endemic minerals in Jiangxi Province, accounting for the top 7 and 12 of the secondary status. The reserves of many minerals occupy a pivotal position in Jiangxi Province and even the whole country. For example, the reserves of tungsten mines account for 7.9% and 5.85% of the national and world respectively.

   Second, problems in the development and utilization of mineral resources in southern Fujian

In terms of resources, the utilization level of mineral resources is not high, and resource waste is serious. The total recycling rate of mineral resources is 30% to 0%, which is 10%-20% lower than that of developed countries. The comprehensive utilization of symbiotic and associated minerals only accounts for the total. One-third of the total recovery rate is less than 20%. At the same time, in order to pursue short-term economic benefits, some mines have a problem of abundance of poverty and abandonment of poverty, and valuable resources such as tungsten and rare earth have been drastically reduced. In addition, due to the backwardness and simplicity of production technology and technical equipment of some high-energy enterprises, the environmental protection facilities are imperfect and the scale is small. In terms of development and utilization, the scale of the enterprises is small and scattered. There are 1266 mining enterprises of various types in the city, no large mines. 12 medium-sized mines, accounting for 1.02% of the total number of mines, accounting for 21.75% of the output value of mining and dressing industry; 843 small-scale building materials, accounting for 68.76% of the total number of mines. There are 115 state-owned mining enterprises, accounting for 9.4% of the total number of mines. The output value accounts for 49.3% of the total mining industry; 327 collective mines, accounting for 26.7% of the total number of mines, the output value accounts for 24.9% of the total output value, and 579 private enterprises account for the mines. 47.2% of the total, the output value accounted for 17.5% of the total output value; one Hong Kong-funded enterprise; 204 other economic type mines, the output value accounted for 8.3% of the total output value. The product structure is low in level, and most of the mineral products are mainly for selling raw ore and primary products. Although the mineral processing industry developed in the 1990s, the scale of the company is small, the starting point is low, the product structure is single, and there are few high-tech and high value-added products. The repeated construction of primary products has resulted in vicious competition at low prices, and the advantages of mineral resources have not really turned into economic advantages. On the one hand, the backward equipment of the enterprise cannot be reconstructed or updated in time, resulting in low conversion rate of scientific and technological achievements and low conversion rate of industry; on the other hand, the industrial technology base is weak, and the development of emerging alternative industries and high-tech industries lags behind.
