RE protection and efficient use of imminent

"Since the reform and opening up, China's rare earth industry has made considerable progress, rare earth permanent magnet material production accounts for over 80 percent of global output. However, while China has a rare earth resources superpower, but it can not be called powers." Recently, the Chinese Academy of Sciences , a researcher at the Institute of Physics, said Shen Pocan interview with reporters.

Shen Pocan pointed out some of our rare native large ore long-term over-exploitation, resulting reserves the rapid decline; some places open tailings dam accumulation serious, not only exacerbate environmental pollution they cause in which waste thorium resources; at the same time, our research on issues related to rare earth inadequate investment, lack of core technology restricts the sustainable development of rare earth industry.

Shen Bao root appears that China should raise awareness of the importance of rare earth. The rare earth elements such as clear as an important strategic element in the country, strengthen the protection of rare earths and other strategic resources and use as soon as possible in the form of legislation; further improve the approval system of rare earth mining rights licenses; strengthening of rare earth resources, rare earth materials and industrialization process issues related to basic science and technology research and investment, accelerate the establishment of relevant intellectual property system; comprehensively promote the rational structural adjustment and optimization of the rare earth industry chain.

Shen Pocan proposal explicitly main Bayan Obo, Inner Mongolia, East mine for locating rare earth mine, no longer be the main iron ore mining, pay close attention to the assessment, in order to study and implement without rare earth minerals such as limonite Bayan Obo main alternative, the East Mine native ore feasibility; conducted as soon as possible ways to re-use value and technical secondary rare earth resources in Baotou Rare Earth tailings dam, significantly reducing the amount of rare earth ore mined; and strengthening solid waste tailings rare high value the use of Green, resources, to achieve the second rare earth-containing solid waste resource efficient reuse of high value; accelerate resource-saving study were associated with rare new functional materials, expanding the high abundance of lanthanum, cerium, yttrium and other elements in the Rare Earth Functional Materials Applications in achieving balanced and efficient use of rare earth resources, while reducing unnecessary separation of rare earth elements.

"Conservation and utilization of heavy rare earth resources in our country need to be strengthened." Shen Pocan finally stressed the need to re-situ leaching of the existing mine, heap leach mining techniques such as dip and pools caused by environmental pollution comprehensive assessment and audit, in reducing Under the premise of pollution and protect the environment as much as possible to improve the recovery rate of heavy rare earths.
