Minerals Development Management Division: Why the National Rare-earth Iron Mine Planning Mine

Recently, the Ministry of Land and Resources delineated the first batch of rare earth and iron ore national planning mining areas. The planned national mining area of ​​rare earth minerals in Quzhou area includes 11 blocks in the exploration area, mining area, and prospecting area. The total area is over 2,500 square kilometers, and the predicted rare earth prospective resources are about 760,000 tons, including medium and heavy rare earths. The reserve of resources is about 710,000 tons. The identification of resources is expected to increase the current reserve of proven reserves of medium-heavy rare earths by 80%. In 2009, 3,444.95 tons of rare earth oxides were mined in this area, and all rare earth production in Jiangxi Province came from here.

Established an iron ore national planning mining area in Panxi, Sichuan. There are good prospects for prospecting in the deep and peripheral areas of the old mining area in Panxi area. The total area of ​​Panzhihua and Baima mining areas is more than 460 square kilometers, and the prospective resource of vanadium-titanium magnetite is predicted to be 13.6 billion tons. The existing capacity of 16.83 million tons / year.

What is the purpose and significance of delineating rare earth and iron ore national planning mining areas? The reporter interviewed the head of the Mineral Development Management Department of the Ministry of Land and Resources on related issues.

The aim is to strengthen resource protection. Rare earths are one of China's major mineral resources and protective mines. At present, China's rare earth reserves only account for about 1/3 of the world's total, while supply accounts for more than 90% of the world's total. This is obviously not sustainable. At the same time, the mining and processing of rare earths have to pay a great environmental cost. First, the mining of rare earth minerals caused large-scale excavation, the forests were cut down, the soil was bare, the gullies were scattered, soil and water was lost, and a large amount of soil erosion destroyed the cultivated land. The second is that emissions from the mining of rare earth minerals cause serious environmental damage. Therefore, the establishment of a rare earth national plan mining area is aimed at strengthening the protection of rare earth mineral resources. This is not only the protection of rare earths as a depleting resource, the need for long-term sustainable use of resources, but also the need to protect the ecological environment.

Iron ore is an important shortage of bulk minerals in China. In recent years, it has been ascertained that the reserves and extraction volume have continued to grow, but the dependence on imports has continued to rise, and currently exceeds 50%. Therefore, it is necessary to increase the intensity of iron ore prospecting and exploration in the country and effectively increase the ability to guarantee the shortage of mineral resources. The establishment of an iron ore national planning mining area is a macro-vision for iron ore prospecting and mining management, which is conducive to strengthening the macro-control of iron ore resources.

The main purpose of demarcating the rare earth and iron ore national planning mining area is to compile plans for the exploration and exploitation of state-planned mining areas in the prospective areas of important rare earth and iron ore mines in China, and carry out preliminary inspections, census and necessary inspections by the Central Geological Survey or provincial-level financial special funds. Detailed investigation, find out the resources at home. Formulate plans for the establishment of mining rights, place mineral rights in an orderly manner in accordance with economic construction and market demand, conduct reasonable exploration and development in phases, control the intensity of exploitation of rare earth advantageous minerals, increase the supply capacity of mineral resources that are in short supply, increase the efficiency of resource use, and protect the ecological environment. Enhance the ability of macro-control of rare earth and iron ore resources, and promote the sustainable development and utilization of national important strategic mineral resources.

What is the basis for delineation is the importance of resources. Resources that are designated as national planning mines should be particularly important. China's ionic rare earth resources have unique advantages in the world. Zhangzhou is one of the major origins of ion-type rare earths, especially ion-type medium- and heavy-earth rare earths in China. Its mining targets and production accounts for about 70% of the country's medium and heavy rare earths, which occupies an important position in the world. Panzhihua and Xichang are one of the richest areas of vanadium-titanium-magnetite mineral resources in China and even in the world. It has been ascertained that the reserves of iron ore resources are nearly 10 billion tons, accounting for about 15% of the national iron ore resources reserves. Among them, about 9.6 billion tons of vanadium-titanium magnetite accounted for 83% of the country's reserves of vanadium-titanium magnetite; reserves of vanadium resources were 18.61 million tons, accounting for 52% of the country; and titanium resources were about 618 million tons, accounting for the national ilmenite 95% of resource reserves.

The second is obvious geological features. According to expert opinion, most of the Yanshanian granite weathering crust in Yanzhou has ionic rare earth ore deposits. The planned mining area includes the discovered and being exploited ionic rare-earth deposits, and most of the Yanshanian granite weathering crusts that may find large- and medium-sized rare earth deposits in the future. There are many iron ore mines in China and it is difficult to choose more smelting ore. Panxi region is a rare iron ore mine distribution area in China. It has excellent metallogenic conditions, great prospecting potential, is suitable for large-scale mines, is conducive to comprehensive utilization, and has a unified plan. The advantages of implementing scale development.

Third, the conditions are more mature. Ganzhou rare earth mining, production, processing has formed a relatively complete industrial chain, a relatively sound management system. The actual mining capacity of vanadium-titanium magnetite in Panxi area is more than 30 million tons/year, and it has a good foundation for delineating iron ore national planning mining areas.
