Focus on rare earths are so rare

Rare earths in aviation, aerospace, electronic information, steel, non-ferrous metal, machinery manufacturing, petrochemical and other industries widely used. Although the amount is small, but the effect is remarkable, play a modern industrial & other; Vitamins & throughout; Role, produce huge radioactive economic benefits

recently, for public opinion & other; Rare earth could become China's important bargaining chip for the counter & throughout; Problem, the National Development and Reform Commission officials made it clear that & other; If anyone want to take advantage of our exports of rare earth products, the used to curb on the development of China, so I want to but the central Soviet area people, the Chinese people, will not be happy & throughout; 。

at that time, the society of rare earths. So, & other rare earth; Rare & throughout; Where is it? Rare earths have applied? What's the advantage of rare earth industry in China? To solve these problems, the reporter interviewed the relevant experts.

in fact, rare earths are widely used in our life. Watch TV every day, for example, its bright red came from rare earth element europium and yttrium; Carrying a camera, rare earth element lanthanum is in the lens; In the everyday use of mobile phone neodymium rare earth elements; Rare earths in aviation, aerospace, electronic information, steel, non-ferrous metal, machinery manufacturing, petrochemical and other industries widely used. Although the amount is small, but the effect is remarkable, play a modern industrial & other; Vitamins & throughout; The role of the generate huge radiation economic benefits.

first of all, the resources advantage. China merchants securities analyst said that as of 2018 global total of 1 rare earth reserves. 200 million tons, our country has 44 million tons, accounting for more than 38%. At the same time, occupy a more important position in advanced manufacturing of heavy rare earth ( Represented by dysprosium, terbium) Has a unique advantage. In the late 1960 s, China discovered the world in ganzhou rare ion adsorption type rare earth mine, the mine has the complete partition, high economic value, choose don't easily, low radioactivity etc, in the rare earth yttrium, dysprosium and terbium, heavy rare earth elements in China's industrial reserves of 1. 5 million tons, ganzhou in jiangxi province accounted for 36% of these a, contains rich type yttrium heavy rare earth mineral resources are more unique in the world.

second, mining, smelting separation ability. In China, China merchants securities analyst said in rare earth mining, smelting, separation, purification of the absolute leading position, has the strong global rare earth minerals production line years about 19. Output of about 120000 tons, 50000 tons, China, accounted for 62%; Global production about 14 rare earth smelting separation. 60000 tons, of which 12 Chinese production. 50000 tons, accounting for 86%. The reporter understands from ganzhou city bureau of ministry of ganzhou ionic rare earth mining and processing more than 40 years, has been leading in the domestic field of ionic rare earth, rare earth mining in the south, separation, metal smelting technology research in the international leading level, industry accounts for a third of the country's total.

once again, the application of continuous chain extension. Take advantage resources and smelting separation, China's rare earth industry chain extension, with the most widely used rare earth ndfeb permanent magnet materials, for example, at present our country ndfeb production is close to 90% of the world, high-end ndfeb production is close to 60% of the global total.

　　“ However, we also want to see your own shortcomings. ” The original hunan rare earth institute of jia-xiang liu said, because the rare earth technology research in China started late, in many areas has been abroad & other; Throughout the mark &; , on a lot of rare earth products, although the largest capacity, but the technology patent basic it is abroad. As the most widely used rare earth permanent magnet materials, the domestic enterprise production permanent magnet motor is not only to pay royalties, but also export quantity limitation by agreement.

　　“ Such as scandium aluminium alloy, high strength, light weight, is key to the aerospace materials, we have mastered the core technology independently. At present, is located in hengyang city pak sha chau industrial park of annual output of ten thousand tons of high-performance rare earth aluminium alloy casting production line is igniting, the next month will be formally put into production. All three phase of the project is completed, annual output value will exceed 40 billion yuan. ” Jia-xiang liu told reporters.

in addition, the reporter understands from ganzhou city technology bureau, the rare-earth exploration, mining, smelting, the material, the comprehensive utilization of resources, the respect such as mine environmental governance, the city undertaken and completed more than 400 provincial-level projects. “ The comprehensive utilization of resources of ganzhou in jiangxi demonstration base & throughout; “ Rare earths green extraction and environmental protection technology and the integration & throughout; Such as a number of major r&d projects has achieved fruitful results.

the payback period of photovoltaic power generation system of energy EPT ( Years) = all manufacturing photovoltaic system energy consumption/photovoltaic power generation system power generating capacity, namely photovoltaics value-added effect.
